Hi,

I wanted to repair and service an Omega Seamaster DeVille with a monobloc case. It has a two-piece stem so I pulled the crown.

Turns out I pulled the crown to bits :gym: That has never happened before LOL. The rubber snapped in the process.

Did I just ruin a perfectly fine original crown or can it be fixed?

It just gave way after many years. Replace the gasket if possible and put back together. Put it back together, maybe you will have to slightly press the outer rim of the washers with a staking tool before fitting so that it so slightly widened to make a good fit.

Just replace it with a new one.

New crown.

I would but this is the original signed crown. These are expensive and the watch will be worth quite a bit less if I fit a generic crown.

Can't find a gasket though and a new original crown is 20 GBP. The reference number is the 14915 by the way.

Correct. Beside, a good principle in watchmaking is to repair where possible. Otherwise we could be just called parts swappers.

Would you happen to know where to find a new gasket for the crown?

I didn,t think a new original crown would be this inexpensive.

Yup, it's less than I expected as well. Bought original crowns for 50 GBP before.

Neither price is expensive and well worth for a valuable watch.

I would say if you are really set on using that particular crown JB weild is worth its weight in watch crowns. Cold weld and a new gasket.

?!? Promising cold weld is the same as promising cold fusion - physics doesn't allow that. Read above to learn how it can be repaired without using gluse.

Jdm I think you mean modify the omega winding stem to get a friction fit right...

No I didn't meant that but never mind, I'm done with this topic anyway.

      Looking for Pocket watch to wrist watch conversion cases

      By mbwatch · Posted

      I am aware of one eBay seller who does cases for some American pocket watch sizes and also sells a case tube & sleeve assembly to work with American negative set keyless https://ebay.us/m/qa0ubk Also I have seen this seller many times but have never been clear on how they handle stems and crowns. https://ebay.us/m/4mhfEr I general though I don't think there are a lot of these cases out there, just a few sellers custom making them or adapting AliExpress cases somehow.

      I haven’t seen glue here before…

      By Nucejoe · Posted

      What type of glue you figure it was. I wonder if acetone dissolves super glue.

      What's the movements so we know what size cases you're looking for and what are the setting requirements.

      Bezel for 1954 Rolex 6581 Oyster Perpetual

      By LittleWatchShop · Posted

      As I am getting close, I would like to know the total thickness of the bezel (top to bottom).  I am working on two solutions--one is thinner than the other.  The crystal sits pretty proud relative to the bezel, and seems consistent with the pictures I have seen.  But, actual measurements would be nice.

      A little bit of superglue and you'll be good to go Although maybe if you had a laser welder you can weld the spring back together. Typically I've only seen it on blued steel Springs and on one occasion a modern spring? The modern watch was a Rolex watch that came and that was literally filled with rust including the barrel was filled with rust in the spring was in a whole bunch of little pieces. I have to wonder if that was an aftermarket mainspring . Then I'm attaching a PDF the Elgin watch company as you can see instigated a study in the 30s find out why mainsprings were breaking. I do though wonder if perhaps there may be a flaw in their study? One other things I wonder about is the metallurgy of the early steel Springs versus the later generation of blued steel Springs whether the metallurgy as part of the problem but in a case they did a study and have attaching a PDF. Because of the study any time I do anything with the blued steel spring when I actually cannot get something that's not blued. Once the spring is cleaned I'm very careful to not to touch the spring with my fingers because I don't want to have a problem with the chemicals on your fingers causing rust and I very carefully get lubrication back on the spring as fast as possible just to avoid these unpleasant situations. Then yes it is interesting one minute you of functional spring and the next minute you have lots of little pieces of spring. For my own personal Elgin pocket watch I put a steel spring and in this happened I'm also guessing that when one layer breaks it sends a cascading shockwave through the spring and that's why it breaks all the way across because after all there is a lot of energy in the spring when it breaks. Oh and my theory on the metallurgy is based on things have improved and for the most part I don't think I've seen a shattered spring in quite some time.   Elgin_Mainsprings.PDF
