I can sleep nicely knowing that I have learned something useful today
This is why pilots love this watch. During pilot training, you're trained to use a circular slide rule for fuel consumption, wind correction angles etc. The Omega Speedmaster has a similar feature called a Tachymetre, which can measure distance and speed, but because it lacks a rotating bezel and three other scales, it isn't quite as versatile as the Navitimer when it comes to calculations. Great video.
I once owned a watch with slide rule bezel. I have used a linear slide rule a lot so I was able to use the watch bezel. I had ideas that I could use the watch in a restaurant to calculate the tip. At some point I realized that in the dim lighting of a restaurant I couldn't read the small numbers of the bezel so I eventually sold the watch.
What a great overview of the slide rule bezel! Thoroughly entertaining to watch and very informative too! Thanks Jayson!
Thank you sir.
I have watched many Navitimer slide rule tutorials BUT this is THE best video on how to use this tool. Thank you!!!
Definitely a robust review of the slide rule - thank you for this! Your content is always so thoughtful.
Great video. Thank you for making - especially with a Breitling. Just one comment for your next, (and I'm sure you have already caught this), at 8:50 when you convert 88 miles into km you would slide the 88 on the outer ring to STAT inner ring. Then read the outer result from inner KM marker. Not over MPH then read from 10. Great video. Think of this as a test to see how many focused on your slide rule instructions. Did anyone else catch this?
No, I think he's correct. If you go back to 8:20 where the outer bezel reads the red 60 and take the reading of the blue inner 10 marker, it reads 10 thus equating to 100 km/h.
Thanks for thinking about this. Appreciate the comment, but just to be sure I understand your thinking, are you saying 60 miles is equal to 100 km? Breitling's were set up to include this conversion quickly by applying a marker called STAT which stands for statute miles which is known as the US miles measurement. If you align 60 to the inner STAT you get 96.x from the km marker. The real answer is 96.56 km. In my original comment, the same applies. 88 Miles is equivalent to 141.6km. He says the right number, 141.62. But look closely at the dial. He's showing 144.x. His dial is wrong because his method for conversion is wrong. Just like 60 miles is not 100 km. It is close, but his slide rule has the KM marker for a reason and it is not intended to be compared with the inner 10 but with the inner STAT. One could always memorize the conversion, Like memorizing 60 is to 96.56. But the KM and STAT already do that for you. He does present it very nicely, I just wouldn't want folks to make this error when the correct approach is available on the dial. @@milk-it
It's decades ago since I used a slide rule (or logarithmic table), but this video brings back memories. I am currently waiting for my Citizen Nighthawk, and I cannot wait to play around with the slide rule on this watch. I still have my old slide rule, btw ... just never use it with a HP 11C calculator on my desk.
I remember seeing a sliderule in my Highschool library. It was a relic already by the time I was born.
Such a fascinating description of how to operate Slide Rule bezels on watches here. I am going to have to rewatch this several times to master the use of the Slide Rule on my Seiko Flightmaster. A great educational video here my friend. ✊
Another great video Jayson. Very interesting.
Excellent review and instruction. I will have to watch a couple more times to get it and practice but i understand the basics now.
Very good, a start to make my new watch more useful.
Really great video!
Great video! The math nerd inside of me loved it.
This is the best I’ve ever heard it described, thank you
Love the avatar man. Haha unicorn gundam
I never paid much heed to Breitling as a brand but the Navitimer fascinates me and has become my next acquisition target... very collectible and a really useful gadget as well as a conversation starter!
Great video! Thanks a lot!
Glad you liked it!
Educational videos, I like it.
Slide rule advantage gets better if you have multiple questions about a similar ratio.
Calculator can only give one result at a time..
Slide rule will give you all answers related to that ratio all at ounce.
Ugh….i have a headache. I’ll have to re-WATCH this again few times.
You'll get it, it's not hard!
Awesome video. I’ll make sure to rewatch when I finally pick up a Navi!
You will in time my bro. Waiting for mine too.
@@DesignAtelier oh awesome! Definitely hit me up if you do! Have a great night my friend.
I 100% agree. I have my smart watch which discharges the more I use it and is pretty much paper weight by end of the day. Yet my mechanical automatic watches just keep ticking as long as I am moving them. They tell the time, Have chronographs, navitimers and just wont die. Which I think is awesome.
Being a computer nerd I have a newfound respect for old outdated systems as you said.
My main issue with smartwatches is that they all look like black squares when worn... Irrespective of whether it is a $20 Chinese junk or a $2000 special edition. They all look the same. The dial comes to life only when I look at it.
I don't understand why smartwatches have become a craze.
Citizens Nighthawk has a slide rule, and it has eco drive so you don’t have to change the battery and the accuracy is excellent.
I’m seen those. Love them too.
@9:25 if i want to get to my destination in 45 mins and it is 1 mile away i need to travel 92mph ? i must be missing something , a speed of 92mph would travel much more than 1 mile in 45 mins? Does he mean if the destination is 77 miles away and i want to arive in 45 mins i should be traveing 92 mph because that makes much more sense.
You are absolutely right! Thanks for catching that.
@@DesignAtelier i just found out what a slide ruler was from another navitimer watch vid and am completely fascinated by it . great vid !
Thank you for video @@DesignAtelier . Using @greek42069's interpretation, what speed do you need to travel 77 miles in 45 minutes, we can slide 77 over 45 and lookup inner MPH and read the answer 102.7 mph.
Very
interesting.
At the 10 minute mark you write 0.3 Gallons per Mile, but say 0.3 Gallons per Hour. I'm afraid my consumption is much closer to the former :)
Very interesting video, thanks for posting!
are you good bro I have bought a model of this watch, but it is not a navimeter, but a tourbillon model. Are the numbers engraved on the rotating ring the opposite of the numbers on the dial? How is this item calculated?
سلام دوستان دفترچه راهنمای این ساعت روازکجاباید تهیه کنم؟
Where can I find the interactive slide rule Breitling that you’re using?
I custom built that on my ipad
@@DesignAtelier Ah…perhaps you can post a video with instructions on that process? 😁
A M A Z I N G ! ! !
Wish I had this in school
I wish I could say I was smarter having watched this, but I fear I'll never master my Navitimer's slide rule. But I still love love love my Navitimer. Thank you for this video.
its the true collectible smartwatch. I would love a navitimer nonetheless if I had one
Get an inexpensive standard slide rule, and use the slide rule geek sites to learn how to use it. Once you realise that there is no meaningful difference between the way in which you use a straight slide rule and the way in which you use a circular one, you will use your watch rule with ease. I would recommend a circular Concise N28, and a "modern" plastic straight pocket rule, six inches or so in length.
I still don’t get it 😢
My head just can’t keep up. I so want to understand this but I’m so stupid. Urgh.
I have a rotary clone of this watch in the picture. The numbers are reeeaaaallly small. Hard to see but they are there.
If it’s one mile away and u want to get there in 45 minutes u should be traveling at least 92 miles per hour 😂🎉 LOL I think the slide ruler just broke his brain. Omg this is hysterical. How bad every video is on the use of a slide ruler
