Hi All, looking for some help identifying the correct crystal type for a Tudor Advisor Alarm ref 7926 circa 1958. The watch has a retaining bezel over the crystal which is .5mm thick with an outer non stepped diameter of 29.4mm. Overall height is 3.7mm. Any help would be much appreciated.

I would use a fine sanding block, sponge type or paper on wood. A so small difference is done easily, check often the bezel fitting to not remove too much.

Big thanks to JDM for the idea with the sanding block. Ended up 3D printing a holder to support the crystal in a drill press so i could reduce the outer diameter while it was rotating. Worked perfectly.

    • 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.
    • 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.
    • 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
