I can't say this enough but THANK YOU FOR THIS. If I were just getting into watches right now this would basically be my most anticipated video series on the subject. Your videos are truly awesome and I hope it helps newcomers.
Thanks--you gave me a new appreciation of quartz movements. I just got into mechanicals, and was looking down my nose at my old quartz Seiko and Casios. Now I'm wearing 2 at a time!
Thank you very much Mark ! Your videos on quartz watches make me appreciate my quartz pieces more ! Mechanicals aren't the only ones to be deserving of appreciation !
Just a little thing to note: the automatic Swatch Body & Soul model can be opened and serviced. The caseback crystal is pressure-fitted and held in place with a metal tension ring.
I was looking at mechanical watches a few years ago, but thankfully discovered that the Swiss Certified Marine Chronometer title doesn't mean accurate enough to determine longitude reliably while at sea in the case of a mechanical watch, while the same title does in the case of a quartz watch before I spent any money on an expensive watch that's literally an order of magnitude less precise at keeping time than a $10 Casio. The sad thing is that this level of accuracy was achieved with mechanical watches in the 1700s to win the Longitude prize, but watchmakers both then and now get paid more to make shiny jewellery for the conspicuous consumption crowd than they'd ever get making well engineered, precise instruments.
As someone always drawn to elegant mechanical devices, I now have much more respect for the quartz movement. Quartz tuning forks, pretty sweet! Though not as cool as that Accutron. (Great series!)
I have so much more respect for quartz movements now. I still love automatics because of their complexity, but wow... had no idea quartz used an oscillating quartz tuning fork.
Joe Joe Quartz get a bad rep because cheap watch will have a quartz movement (a low quaility quartz but still battery powered none the less.). There’s also a part of history when quartz almost killed the mechanical watch industry but that’s for hardcore watch nerds. I myself have a few quartz and they have been accurate for years, never have to adjust them except for daylight savings. I still prefer my mechanical and auto movements but Quartz still holds a special spot in my heart because my very first watch was a Timex Quartz watch.
Great video! Thanks for sharing. One thing I want to say is that the automatic Swatch is serviceable. Swatch may not want to do it, but another watchmaker will. They can pop the plastic (or glass) out of the back, and work on it. I have the same basic model and I've had it serviced twice: once by the store I bought it from and once by a different watchmaker.
grew up on long island. moved away at 24. growing older, when i visit family i notice more and more that i hate the accent. thought i would have trouble watching these vids because of that. but the quality of content makes me completely overlook the voice. if/when i buy a watch in the future i'll try to do so from you. thanks for teaching me so much.
Fantastic video. This was super useful to understand the various movements and their history. Even more interesting to discover quartz (although used on most cheap range watches) is actually more accurate than automatic watches.
nutnfancy wow that's cool. Another "famous" UA-cam commenting on one of my favorite pages....I knew you were a 135 pilot but no idea you were into watches!
good video very informative. I new most of the quartz if not all. you have just made me think stronger that quartz movement is the best and most accurate. good video explaining the 2 movements side by side through skeleton watches. some people might not have ever seen inside the watch in it's working state.
21,600 vph is 3hz or 6 ticks per second. 28,800 is 4hz, and 36,600 is 5hz. The number of hz includes clockwise and counterclockwise rotation of the balance wheel, and each direction causes a tick, so that's why a 4hz movement ticks 8 times per second. Great vid! I'm loving these more technical videos.
+Long Island Watch Yeah... :P of course the one time I decide to get technical I make a mistake. I'm looking forward to more videos in this series! Keep up the great work on the channel. Cheers, Grant
Another very good presentation. However, it needs a significant correction: 36 kbph = 5 Hz 28.8 kbph = 4 Hz 21.6 kbph = 3 Hz 18 kbph = 2-1/2 Hz 3.6 kbph = 1/2 Hz (my grandfather clock) Every complete cycle of the balance (or pendulum) has two beats. Your narrative stated twice the actual frequency as if each cycle had only one beat. A good topic would be about adjusting and regulating a mechanical movement, the difference between them and how they're performed, with a little about how some of the mid and high grade quartz are regulated at the factory during final inspection and testing.
Thanks! I covered it in more depth in another watch and learn that was published recently. I do realize that a back and forth beat of the balance is one tick, thus the doubling. Why I said it wrong, I'll never know!
Great series, Marc! I've also enjoyed the "round-ups" of field watches and watches under 40mm. I'd LOVE to see a similar video running through a handful of the watches square and rectangular case shapes available from your store. It's hard to get a sense of what size really means for some of those watches, and how they compare to each other or would wear on the wrist. I think it'd be very useful!
another great job. need to get one of those Accutrons. I look forward to video on chronographs and maybe you could explain why vertical coulomb wheel is desirable
When I look at the movement of my Tag Heuer Carrera 1887, the escape wheel moves extremely fast. And being a Chronograph, I love to see the parts moving when I start it. It`s a piece of true craftmanship. To be honest, I gave up Quartz watches a long time ago. Fell in love with the automatics. Simply because of the fact how they work. Yes, Quartz watches have their place. In fact, even I say, if you`re a, let`s say, construction worker, wear a Quartz. It`s most likely tougher than a automatic and more accurate. In the end, get what you like. Very nice video by the way. Very well explained and very informative.
When I was young I used to wear a Sector ADV 4500 quartz powered chrono, (I still got it but never worn anymore) it has an interesting feature to optimize battery consumption: when the battery power decrease, instead of moving the second hand once per second, it moves it once every 2 seconds, to save power and double the remaining duration! A very interesting feature for this (at this time) very inexpensive watch!
Thank you, for a truly interesting and educational video. I did know already the basics of some of he subject matter but the way you presented the evolution of the watches made for a very coherent lesson and really increased my understanding. The only thing that I still don't understand is why the frequency of the quartz "tuning fork" is fixed, constant, invariable, and independent of manufacturing variations in dimensions, mass, etc.. I guess this must be down to the fundamental physics of the piezoelectric effect. It's a wonderfully valuable and surprising fact.
Are there any modern tuning fork watches like the Accutron that they still make these days? I love the sweeping second hand motion for a battery powered watch. Or are there any hybrids like it that exist?
What is a reputable source for getting an old Accutron? eBay certainly has them, but it doesn't seem the most reliable way to get a undamaged working model.
Thank you for the useful info. Until a few months ago, I only owned quartz watches, so I did not realize that even high-quality mechanical watches vary by a few seconds per day.
a question please: how come the balance wheel turn borth ways with the same speed when the spring is coiled at the maximum vs when the coil has little tension in it (power reserve is nearly empty) - cannot figure this one out.. this would mean that we have a slight difference in time measurment when the clock is wound up to the max and when it is almost going to stop? (i read that mechanical movements are less imprecise than quartz, is it because of this?) thanks and keep up the cool videos!!
Great video and very informative.Can I buy one of your very special Islanders anywhere in the UK ? Thanks again for all your help in better understanding all that goes into watches.
With proper lubrication, no. They are built for it. Hi beat (meaning different things for Seiko and rest of the watch world) basically stops at 36000. They use advanced lubricants and materials that make them have the same service intervals. Want really cool? Check out the TAG Calibre 360 in the Mikrograph. That's 360,000 BPH.
Need to create a watch case where all the mechanisms inside the case are sealed in a total vacuum. Still have gravity to deal with but the vacuum would reduce friction. Lubricants would have to change. Temperature would be of no consequence in that state. Just thinking out loud...
Unless you float the gears on maglev bearings heat will still conduct through the case into the watch mechanism. Even at that radiation will still transfer heat in and out of the watch.
Very nice explanation of the evolution of watches as a function of the oscillator. Note that Bulova quartz watches is based on a frequency 8 times that of the average quartz watch, that is 262,144 which keeps its time plus or minutes 10 seconds per year. I'm sure you already know that and the scope of this video is to go from balance wheel, to metal tuning fork, to quartz crystal. The national time clock is based on an atomic frequency of cesium, which is approximately 9 billion oscillations per second.
Awesome video, thanks for the explanation! About that automatic Swatch - it would be such a cool and beautiful watch if it didn't have Swatch written all over it. Oh well, they were different times when it released
With a typical Japanese automatic (let's say Orient Bambino), how often does the watch need to be serviced to remain accurate? How much does this typically cost and what is involved?
Most say about 5 year intervals, but I say, if it ain't broke, don't service it. A general overhaul is a complete disassembly, degrease, re-assembly and re-lube. Costs vary, I'm going to say it will start at around $100.
Hey, just stumbled on ur channel, great videos. I have a 20yr old Movado quartz that stopped working and brought it to a jeweler and he said it's worth fixing. ..so I'm thinking from ur video that it is jeweled also and 14k.gold plating inside. ..should I fix it?...
21,600 bph is regarded as 3 Hz (Hertz), 28,800 bph equals 4 Hz and 36,000 bph would equal 5 Hz. I was confused about this at first, but apparently there are 2 beats in a Hertz (Hertz is one complete cycle, not a beat).
do you know if it's possible to open up a swatch skin watch by removing the crown and using pressured air through the crown hole to pop the plexiglass off?
Moving hand needs energy. The counter in a quartz watch is designed to count up 32,768 beats before sending power to the motor to move the second hand. Normally in analog quartz watch battery lasts in 3-4 years. If we design the watch to sweep the second hand like a mechanical watch, the battery will last in 6 months. Some quartz watch have sweeping second hand but they need something special to do that.
Nathaniel Wilson - I knew Bulova Precisionist. It uses CR2016 battery that has 3 time capacity of SR626 and it can run only for 2-3 years. Most of watches run on smaller SR626 battery for 3-4 years without replacement. Do you see the point?
What's the average lifespan for a good quartz movement? I have a Seiko that has lost reliability lately. It's 18 years old, battery tests fine, but occasionally it stops for no reason. Thanks! Great videos!.
very nice video Marc. I'm a fan of qwartz and treat mechanical as a novelty of sorts. However, I can see the value of mechanical in a military setting when everyone needs to be on the same page with no chance of battery's going dead
The problem with mechanical in a military setting is that mechanicals are very sensitive to shock. I'm no watch maker but I wouldn't think the repeated recoil of a gun would be good for accuracy.
What about elevation changes effecting movements? I'm living at sea level, but in March I'm heading to Nepal (3,000-4,000m elevation where I'll be). I'll be bringing a Seiko SKX007 for the ride and was just curious. Thank you for these great videos!
Hi great vids! Thank you for the time and effort you put into them! Just a quick question that I hope hasn't been covered here too much (maybe I missed it in your vid?). We saw how the second hand moves several times per second, appearing almost smooth in its movement as the number of beats increase per second....Why then do quartz watches tic, given they beat many thousands of times per second, far far more than any auto? Is it impossible to have a "smooth' moving second hand on a quartz? Thanks
I see. I have a battery operated wall clock that runs with a smooth moving second hand. Wondered why quartz watches didn't. I realize probably apples and oranges, still I wonder why a quartz watch could not be designed to do the same. Looks quite elegant in my opinion.
When a battery operated quartz watch with hands, has a hackable feature, does it disconnect the battery from the stepper motor or the entire movement ?
Hi there I liked your video. I am looking to buy a clock where the hand constantly moves and not ticks ? like the first watch. the constant move. what type of clock am I searching for ?? online ? thanks
It's so refreshing to see a watch enthusiast that actually understand watches to this level of detail
"Thank you very much for watching"
On the contrary: thank you very much for making these videos, they are great.
:)

Excellent episode. Love technology. Please include digital quartz watches (pluses, minuses) and hybrids such as spring drives.
Got it.
I've been glued to the chair watching video after video on this series. Absolutely amazing. Thank you so much for making these
After this video I can much more appreciate my little quartz watch, thank you!!

Really enjoyed and learned!
Love the automatic moments way more than quartz..
Thanks so much Mark!!!
Excellent series, extremely informative and well presented! Thank you so much for creating this!
Great video and well presented information, thank you! Why did the little plastic Swatch quartz die btw?
Not really sure. It wasn't the battery
nutnfancy wow that's cool. Another "famous" UA-cam commenting on one of my favorite pages....I knew you were a 135 pilot but no idea you were into watches!
Gavin Ball he started to get into them, he has like 8 videos about watches.
Aha
Funny, I watch nutnfancy's video's too. Turned me on to the Springfield M1A Scout....

Just started collecting watches. Came across your video by youtube recommending it. Awesome video. Keep it up love it.
These videos are awesome. Thanks Mark. I`m considering dropping out of my teaching degree to study watch repair.
I know it's been 4 years since this video came out but it's still very interesting and helpful.

Its amazing how much we don't know. I've learned soo much watching these videos.
Great episode and that's a great Swatch Mark. I have never seen it before.
the digital clock in my honda civic looses almost 2 minutes a week. i don't know why.
Probably needs unleaded. LOL
Matthew G Check the wiper fluid. :P
Needs a 800 CCA lead acid battery to excite the liquid crystal faster.
That's the tachometer. Not the clock.
that happen because you drive fast and travel in time
This is great content. I'm watching the whole series from the beginning. You've won a subscriber

Thanks so much for the terrific education Mark. I’m watching all your videos. Lori
Great Video Mark, my wife plans on educating her kids @school with info from this video. Take care!
Shinta0SaINt That's great, thank you!
Another outstanding video Mark! Keep them coming! I really enjoy the technical aspects of watches
Thanks!
swatch watches are heavily collectible, the quartz one shown here is awesome.
you should have continued with the spring drive and pendulum technology.
mariamik104 for the price they are cool watches shame them being sealed and thus doomed to die :(
Thank you, for a truly interesting and educational video. I did know already the basics of some of he subject matter but the way you presented the evolution of the watches made for a very coherent lesson and really increased my understanding.

Another great informative video. Keep uploading Marc.
Just finding these videos now and I’m loving them. Thanks so much!
Thanks!
I like how you used see through cases to highlight the differences- it's visually easier to tell them apart!
Yes, thank you. Fortunately I have a deep collection to draw from.
Another fantastic video!!! Perhaps you can do a video on the various watch brands and what makes them special...
Thanks, great idea!
Are there any modern tuning fork watches like the Accutron that they still make these days? I love the sweeping second hand motion for a battery powered watch. Or are there any hybrids like it that exist?
Great video. Didn't know that we had something in-the-middle between quartz and mechanical. Going to get myself a nice Accutron...

Quite informative. Thanks to you, I now know how my watch works.
Great video!
I have a question. Do high-beat watches suffer from higher wear than regular beat watches?
With proper lubrication, no. They are built for it. Hi beat (meaning different things for Seiko and rest of the watch world) basically stops at 36000. They use advanced lubricants and materials that make them have the same service intervals. Want really cool? Check out the TAG Calibre 360 in the Mikrograph. That's 360,000 BPH.
what is seiko's definition as opposed to the rest of the watch industry? thanks for the great video
Need to create a watch case where all the mechanisms inside the case are sealed in a total vacuum. Still have gravity to deal with but the vacuum would reduce friction. Lubricants would have to change. Temperature would be of no consequence in that state. Just thinking out loud...
Unless you float the gears on maglev bearings heat will still conduct through the case into the watch mechanism. Even at that radiation will still transfer heat in and out of the watch.
Yepperz. I recon so.

Excellent, informative and really facinating, and great work.
Thank you.
Awesome video, thanks for the explanation! About that automatic Swatch - it would be such a cool and beautiful watch if it didn't have Swatch written all over it. Oh well, they were different times when it released

excellent. pls provide a list of the cosc quartz watches in a future video
Sweet looking cuff link! Where would I find something like that?
I think it was cufflinks.com
Long Island Watch Thx.
Were you a KC-135 pilot as I saw in a remark below? I used to repair the navigation systems on them in the early 70s.
Great video. Do you happen to know the specs of that swatch body and soul. Case diameter, lug width...etc? Thanks.
Total gear head and dig these videos, I’d love to see a breakdown of the original Hamilton electromagnetic watch movement.
Fantastic video - love the series.
Thank you.
Once again great watch & learn video Marc
thank you.
Thx Mark! Waiting for watch and lear 5!
Thanks for making these videos, Mark!
Excellent information, Marc, well explained.
Why is it that if quartz watches have far more movements per hour the second hand still jumps, rather then a smooth motion?
Because the quarts is seperate to the mechanism. The energy is stored until 1 second passes then transfered thorough the mechanics 😁
Moving hand needs energy. The counter in a quartz watch is designed to count up 32,768 beats before sending power to the motor to move the second hand. Normally in analog quartz watch battery lasts in 3-4 years. If we design the watch to sweep the second hand like a mechanical watch, the battery will last in 6 months. Some quartz watch have sweeping second hand but they need something special to do that.

That swatch automatic looks awesome. Which model is it?
What's the average lifespan for a good quartz movement? I have a Seiko that has lost reliability lately. It's 18 years old, battery tests fine, but occasionally it stops for no reason.
Thanks! Great videos!.
With service, 10 or 20 years.
Long Island Watch Thanks you!
Wonder if Bulova would make Solar ver Accutron. If they do, I'd b interested in getting one.
that bulova looks amazing can the swatch irony be serviced
burger6599 no. It is not serviceable.
very nice video Marc. I'm a fan of qwartz and treat mechanical as a novelty of sorts. However, I can see the value of mechanical in a military setting when everyone needs to be on the same page with no chance of battery's going dead
Absolutely; or, go Solar!
The problem with mechanical in a military setting is that mechanicals are very sensitive to shock. I'm no watch maker but I wouldn't think the repeated recoil of a gun would be good for accuracy.
What about elevation changes effecting movements? I'm living at sea level, but in March I'm heading to Nepal (3,000-4,000m elevation where I'll be). I'll be bringing a Seiko SKX007 for the ride and was just curious. Thank you for these great videos!
Won't matter! Air pressure doesn't have that much of an effect,and that altitude is only a few psi different from sea level, so no worries.
Swatch Irony Body & Soul is a long time favorite of mine.

Because the quartz second's hand is driven by a stepper motor that ticks at one time per second.
I see. I have a battery operated wall clock that runs with a smooth moving second hand. Wondered why quartz watches didn't. I realize probably apples and oranges, still I wonder why a quartz watch could not be designed to do the same. Looks quite elegant in my opinion.

This is so interesting. Thank you for sharing your deep knowledge.
Thank you for watching.
Very good. Hope you can compare in a video what makes Patek Philips cost thousands time more than others
What kind of quartz swatch is used in the video?
Excellent informative video,learnt a lot,keep up the good work.
When a battery operated quartz watch with hands, has a hackable feature, does it disconnect the battery from the stepper motor or the entire movement ?
The entire battery is disconnected, "lengthening" its life.
Ok thank you
My quarts watch is closed back. Is there anyway I can Make it glass back?
Are there any other watches with aesthetics alike the sfk100? Would live any recommendation pls, thank you
Definitely love your videos!!! I have been learning so much
Hi there I liked your video. I am looking to buy a clock where the hand constantly moves and not ticks ? like the first watch. the constant move. what type of clock am I searching for ?? online ? thanks
woww the Accutron is a sick watch
Do you jnow the model name of that quartz swatch?
Marc how accurate is the Acutron tunning fork watch? Better than quartz?
No, + _ 1 / 2 seconds a day .
No, in general, the higher the beat, the more accurate, with a Cesium clock being the most accurate : )
It must be more expensive than the quartz??
"How do you keep a SKX007 wound?" You either have to wear it or put it on a winder. Mine stops after about a day and a half if I don't wear it.
