Roller for 19" Omega Pocket Watch


Recommended Posts

I have a 100 year old Omega pocket watch with a 19" movement. The plateau is broken. Huge crack in it and now it's broken in half! Does anyone have a spare I could buy? Or know of a good source? Nothin on eBay sadly.

There were some different variants of the 19 ligne movement, they al had a bit or bob different so you might have to specify which one you have.
Here is an example of an Omega 19''' LOBNN I happen to have lying around.

Yes with a quick look at the serial numbers , mine 5543286 and yours 5557368 indicate they are made at the same time period around 1919-1920.
The movement is not for sale but I can donate it to you. I have a couple more in my stash so I dont have any use for this one.
If you haven´t changed adress I'll send put it in the mail for you tomorrow.

Wow. You are so kind to me! I really am happy to pay for these parts and postage if you ever want me to. It’s very generous of you. But rest assured that one day I’ll pay the favour forward to somebody else learning the trade.

The address is the same. Thanks again HSL. I’ll post some pics when this one is up and running. I’ve ordered a leather Albert. Let’s try and bring the pocket watch back into fashion. I always wondered what that tiny pocket in my jeans was for!

And here it is completed. It's been a long process. Lots of cleaning and polishing, a new balance staff, replacing 2 cracked jewels, all kinds of escapement issues. Thanks HSL for the roller! Everything is running great now after 12 rounds of dynamic poising. It's within 30 seconds per day in all positions which I can live with. But most importantly within 8 seconds dial up and pendant up. Pretty good for a century old watch.

    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong. 
    • Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
    • this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.  
    • OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.
    • Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
