Great Horology in a Very Affordable Watch

- This is great. I have one watch with dual barrels in parallel, and a couple of watches with the sweet ease of 18,000 semi-oscillations per hour - BUT I don't have one watch with both. Now I can have one for under $100.

That is an awesome find that Favre Leuba, thanks Bill 👍🏽
I'm recommending this guy to everyone I know who is wanting to learn about watches.
What guyz that Dude? Take care, Bill
Bill you are man of the people, thinking about us poor people ❤
Ali, I'm just thinking of myself! Watch poor! Horology rich! Take care, Bill
@@watchartsci I just order one from Etsy as you suggested. Thanks Bill again ❤️🙏
@@AliReza-do5my Ali if you're not part of 'Pretentious Watchmakers' FB page, you might want to join us there... some of use are getting the FL Twin Power too...
@@watchartsci wonderful! I just requested to join you
Just grabbed a Farv'e Leuba Twin Power in green $95 Thanks Bill !
Good move--the supply might dry up pretty soon Breca. Take care, Bill
I just recently picked up a white gold Favre Leuba with the calibre 272. (no seconds varient of the movement you mentioned) Just a incredible watch. Has a very interesting textured case and milanese bracelet
That’s a great looking watch!
Thanks Ced! Take care, Bill
Thanks for another great video, Bill. Favre Lueba certainly made some great watches and they represent excellent value for money these days when found in good condition.
Ever since your mention of two mainspring barrels in parallel in your recent video about constant force mechanisms, I’ve been pondering just how two barrels in parallel helps to even out the force provided by the mainspring(s) over the wind cycle.
With no further mechanism beyond two barrels in parallel, each spring is at peak power when fully wound. The power of each spring follows the power curve common to modern mainsprings, staying level for much of the wind cycle and then it tapers off towards the end.
Combining the torque of each barrel by connecting them in parallel will result in a power curve of the same shape, with a higher peak, plateau and dip towards the end.
All the horology theory books and resources I’ve consulted say that two barrels in series extends the length of the wind cycle, and two barrels in parallel increases the torque available. There is no mention of constant force, only higher torque throughout the wind cycle.
So having two identical mainsprings in parallel (assuming perfect efficiency) doubles the torque available to the movement, but the power output will still vary in the same way it does with a single mainspring.
I was under the impression that dual barrels in parallel was used to supply extra torque to a movement where geometry and availability of space means it’s easier to accommodate two smaller barrels in parallel than a single larger barrel of the same power. In fact, I’ve read that this is the very reason the Favre Lueba 253 was designed with twin barrels.
I’d be very interested in any explanation for how two barrels in parallel could help to provide constant force. I can find nothing beyond bold statements by manufacturers, without any explanation or justification of why it is so.
I found others asking this same question online, too, but no attempts to answer these questions.
Love your videos, always learn something new. Thank you.
As your video suggests, collectors would be well advised to open themselves up to exploring vintage references.
Howard, my advice is to be open to constant force mechanism where they're affordable! Take care, Bill
Great vintage finds Dr.!
Dear GOD that FP Journe movement is beautifully decorated and designed. It's amazing how much just using Rose Gold elevates the appearance of a movement, plus Rose Gold goes so well with Steel.
I want to thank you for getting me into Vintage Watches, I'm a horology fan but don't have the most technical mind so having access to a channel that can casually explain the qualities, peculiarities and rarities of older watches and their movements/etc is so informative and useful.
What’s crazy is that FPJ’s bronze movement models are more valuable on the market. Watch collecting makes no sense but we can’t get enough of it!
Hey Paddy, thanks man! Take care, Bill
Great vid Bill. Thanks
Hey Bob! Thanks man! Take care, Bill
Great video Bill. Double barrels in parallel, what a great example of Constant Force. If only I was lucky enough to have one in a few weeks. Unfortunately, not the Lang and Heyne or the FP Journe.
Best regards, Brian
I am of short attention span lol. I appreciate the 5min format.
Thanks Bill
You're welcome John. Take care, Bill
love the twin power
These are completely under the radar! But incredible 👌❤️👍
That's what I thought too, John. Take care, Bill
Thanks for the tips….
Nice video mate 🥃
Hi Bill,
I would really like it if you explained how two barrels in parallel keep constant torque because as the spring unwinds torque will drop and so will amplitude. On the other hand, two barrels in series when one spring winds down and you get a drop in torque, the other “kicks in” and torque/amplitude increases. In both cases the springs will be shorter, so at the end of the wind the drop won’t be as significant as it is with just one barrel (which normally has a longer spring).
This is my understanding but I would really like to hear what you think of this perspective.
Good point Ben. Double barrels in series do not share the power needed to move a gear train through the main torque of the spring as consistently as two working together. If a spring in series is allowed to 'dip' before the hand-off to the second power source (the second barrel), there could be two added surge/dips in the sequence instead of the ones at the beginning and end of single barrels or two working in concert. However, your point and the points for automatic winders have merit. Take care, Bill
@@watchartsci hi Bill,
To my knowledge, when you have 2 barrels in series there isn’t really two dips because the second one kick in before there is a significant drop in torque from the first barrel.
Interesting watch, similar twin mainspring barrel setup like my Nomos Lambda
J. there are twin barrels in parallel and ones in serial. I believe the Lambda DUW 1001 is serial for a longer reserve. Take care, Bill
I've got an old Farve-Leuba Harpoon ll in my bottom draw. I'm going to get it out for some wrist time.
It does not have double barrels, it has a humble FL-1134 movement.
Very beauty mvmts!
Hi Bill. This brand often pops up on Ebay. I never would have guessed that such an unassuming watch would share so much in common with some of the greats. And to me at least, 35mm is a sweet size.
Great video.I am glad to hear you mention favre leuba its one of my favourite less known brands. Its has a long history but quartz crisis got it good. I am thinking to buy a sea raider 2 daymatic,i would like to hear what you think about the watch if you're familiar with it.Thank you!
Thanks for sharing Chris. Take care, Bill
I'm still old school learning all of the new terms and the oscillations mentioned lead me to believe they are regulated by Quartz. Am I correct? Thanks
No ET. The swing of the balance wheel is an oscillation. Each 'tick' is a semi-oscillation and the 'tock' is the other half of the oscillation. Take care, Bill
Found this exact movement in a Sea-King, which is amazing. How much would it cost to service the movement if its in a not bad condition?
Bill, by looking at the movement, can you see the difference between two barrels in serie or in parallel?
Where do you have to look at?
It might not be visible, depending upon the movement architecture, but dial barrels in parallel will be mechanically coupled such that they must turn simultaneously.
Check this out Ronan: watchesbysjx dot com /2024/03/explained-barrels-power-reserve-energy.html? If both barrel gears are linked to the same top gear in the gear train; then it's parallel. Otherwise series. Take care, Bill
@@watchartsci Thank you! I will read it.
I have had vintage favre leuba watches for the last 30 years.
Dont buy any from India.
Favre leuba was big in the Raj , but now there is a thriving industry in repainted dials and non original cases and movements.
And they have spread all over the world to people who seem unaware .
If there are littes signs of wear , or a brand new looking dial i would steer clear.
Too late S McL-already bought two. One arrived, and the other is winding its way through the India mail system. Both I plan on oiling and re-gasketing and give them my the benefit of my limited talents as a 'Pretentious Watchmaker!' Take care, Bill
Dangit, now I want one. At least they’re cheap. I can sell a G-Shock.😅
Let me know if you get one CT. Take care, Bill
Very nice option, Bill. Never heard about Favre before.
I wonder if you thought about linking your videos with others on related subject, in this case constant force.
UA-camrs do this to increase engagementz
I'll look into it Cesar. My problem is introducing too many users who want nothing but cheap, flippable watches or Rolex-All-The-Time hypnotized. Take care, Bill
Hey Bill
Hey Wayne!
Who would you get to service this?
I'd do it myself, Dino. Take care, Bill
Just checked your website link and it does not work, just a mention👍
Which Website link was that?
@@watchartsci The one in your profile - perhaps an older vid?
