Jewel Bearings - Elgin National Watch Co. WWII Production 

Consider that at the beginning of the process, one round of work pushed through 40,000 individual piece at a time.. by the time that they were completed the process, one jewel at a time was examined, by hand, individually for exact perfection in all aspects by a person! THAT amount of dedication, precision, concentration and mental steadiness needed means that I would have put a brick into my face in a short period of time.. how did these folks do it back then? The tiny size of the dang things! Today it's mostly all done with electronics, remotely and with little human interaction throughout the whole process. I watched this video in it's entirety muttering under my breath in amazement how they got from a blob of man made material to a precise sized and shaped tiny little jewel... Gob smacked... yes, you have to watch this video!

Thanks for posting this. Fascinating process. I wonder if anyone would make a modern version of the film. I imagine the process today is much more automated and the technology involved is way more advanced.

Wow that is a lot of Shellac.

Good documentary! The most important steps have not really changed very much even today, and we still use similar wire laps and centerless grinders to manufacture jewel bearings.

I wonder where all those machines are today. I wonder if they destroyed or are sitting in the dungeons of one of the larger businesses 🤔

Shellac, olive oil, and benzene.

Wow. How many times is each jewel individually handled and shaped by a person. So many steps. Some of them done on mass and in bulk. But so many steps require 1 person to individually shape each jewel. 15-16 jewels in a single watch. Hundreds of thousands of watches. Impressive.

WoW !!!

Boop

Excellent knowledge gained! You have my gratitude!

*leaves for the restroom then comes back* “The fishes are served in the traditional way” *???*

So tedious… Awesome though.

Amazing video. If only it wasn't in such a miserable low quality :(

My question is how they used to do that before the industrial revolution 🤔
