Watch Jewels 

The best explanation on jewels I have ever seen. Great video, this channel is gold :)

I feel like I have attended a Master Class for watches. Your calm and clear presentations make it enjoyable and easy to understand. So now when I watch restoration shows or a watch presentation I know what is going on. Many thanks to you for your videos! Jewels in watches are no longer a mystery to me🎉. Thank you. Peace 💫

The production value of this is awesome. Well done!

I was completely uninterested in wrist watches until I took a closer look and did some history research. The things mankind are capable are truly mind-boggling.

The production quality in this video is amazing. Thank you

In the later 80’s when I dove full deeper into Watchmaking, In a brief conversation with an older gent, I told him of my persuit. He replied “You need to be careful when sending a Watch in for service. Some Watchmakers will steal the jewels from your Watch”. I replied “So you’ll get it back and it’s running fine … “. He say’s “Yeah, you’d never know”! HA. Very well done video, BTW, thanks.

Excellent, excellent presentation. I've recently developed an interest in mechanical watches and have several modern automatics but including a 1940 Bulova American Eagle. I never thought about how they work until now. I always owned electronic/digital watches for their accuracy. As a lifelong mechanical engineer, spent developing heavy equipment, I am blown away by the scale of these parts, and the precision. It's fascinating. I can't fathom how they were able to make timepieces in the 18th and 19th century. The concept of thread infused with diamond to hone the sapphire is mind-blowing. The design of the pallet fork system is pure genius. My life was spent dealing with the comparatively wide design tolerances of machined and welded components... and signing off on many non-conforming parts! Crude by comparison. A watch is on a totally different level and a thing of absolute beauty. I hope it is not a dying art.

Second Time I am Here To Watch Your Relaxing way of Telling Complicated Things Simpel Thanks Mate Keep them Coming ;-)

Very interesting and insightful video; thank you for taking the time to make it. I feel smarter now after I watched it!

Really nice video! Thanks a lot! Perfect explanation!

I got my first mechanical watch a few months ago and just came across your channel. Super interesting video and very well presented! I enjoyed every bit of it. Beautiful shots and I loved the soothing music!

Great content

Thank you so much for this fantastic presentation and easy to understand explanation as well! AMAZING!

WATCH THIS VIDEO AT 1.25 SPEED. YOURE WELCOME.

Amazing camerawork!

Brilliant. Thank you

Fantastic video! Thank you!

Proud to see a true American craftsman at work. Thanks for all you do. - Chris

Thanks, very interesting!

Amazing presentation, thank you!

Absolutely amazing

Very well explained. Thanks!

Beautiful ❤

Well done indeed! Thank you for explaining this in layman’s terms.

this video is so interesting tysm

very informative. Thank you sir! :)

Another great video, so we’ll explained. Thanks!

Nice channel and great explanation! Thank a lot you for sharing.

14:09 I would agree in the sense that crystal bearings don't "make" a watch complex. Manufacturing crystal parts is an incredibly advanced chemical, mechanical, and often electrical demonstration, but their function is in the very simple quality of their hardness; resisting wear and efficiently deflecting friction. Great vid BTW

Great video. Love a US based watchmaker.

Thank you for the video. There is a video on utube of the process of making jewels that was made by Elgin during WW2 Shows process from cutting bule to final polishing of the jewels. Jewel bearings- Elgin national watch co WW2 production.

Now a complicated question by a devoted amateur to a professional. I already have acquired significant experience by making a jewel for a Domina pocket watch 1920. Actually I made it from sintered white ceramic from a kitchen knife and also rediscovered how the opening is made by reciprocating movements and diamond powder. Why the effort? Coz Cousins does not sell such huge jewels any more. I also made the pellet stones this time using rubis from Cousins. The important thing is that now I know that for a mirror surface the diamond powder should be 0.5 um. And now I have to make a 0.58mm roller D-section pin from a 0.6mm roller pin coz this is what I have. It is easier to buy a new roller pin of course but I want to also technologically cover the roller jewel domain. Given the complexity of the holders I used on the watchmaker lathe for the previous tasks I now invest time to figure out how to proceed with the roller pin. There is no info from La Pierrette company on the roller pins manufacturing process so I would appreciate if you share some idea on the subject as to how to approach this task.

Just bought an open heart automatic watch and got really curious what are jewels for, didn't expect to find a high-budget documentary about it 😂😂😂

One thing shappires and rubies are the same base mineral (corundum) with different inclusions

The information and presentation of this video is amazing. but if i could offer some feedback, i had to watch it on 1.25x speed.

I'm a bit older than dirt and came across a timex 400 owned by my father in law. 1960 era actually. 17 jewels west Germany made. This schooled me thanks . Now tell me what military watch you are wearing please . Thanks, Coma

I had to 1.5x to make it look normal

Play at 1.25x. Thanks me later.

I wouldn't say corundum is almost as hard, a better statement would be that corundum is second to diamond in the Mohs scale of hardness. In actually diamond is harder than corundum by multiples. That's like saying a car that goes 100mph is almost as fast than a car that goes 200mph.

Than, why are jewels always red (or pinkinsh) colored, and not blue, green, yellow, or other colors...? Aren't they all synthetic corundum...?

Please give this guy a cup of coffee before another interview.

You said everything twice, do you know that ?

07:30 Nobody should talk that slow. Is this guy for real? It's ridiculous that I have to watch this at 1.5x speed just to follow along. Imagine trying to take notes in class and having to wait 2 minutes for this guy to finish one sentence. I'd fail. It's hard to keep track of people who talk too slow for my brain. He's using SO much slowwwww emphasis that's I can't even keep up with wth he's talking about. This could have been a 5 minute video. Did the director specifically ask this guy to speak that slow? Idgi. It's like he puts a period after every word.

I like the guy but he speaks very slow!! and because of that, I am giving it a thumbs down.

Can you slow it down a bit I keep dozing off
