Hello.  Frliends, I need some advice about how to install a crystal in a bezel.  I consulted you over the last few days about a certain Omega in which the mov'mt exits through the crystal.  As I mentioned then, the crystal was a VERY tight fit in the delicate gold bezel.  How in the heck can I get the crystal installed without risking distortion of that bezel? I have this Omega tool and I can see how it would make installation in a more conventional case easier but can it lhelp me in this case? Thanks.

Oh, I forgot to mention this.  The inner dimension of the bezel through which the crystal must pass is 31.5 mm.  What size should the crystal be? In other words, what should be the interference factor? Cheers.

That tool comes from a complete set for removing Omega crystals. They are re-fitted after with a press.

 

I have documented this in a couple of videos you may find helpful:

Thanks Mark. The pneumatic method for case opening was very interesting! I'm not really surprised that my tool is for removals; just hoping. Unfortunately, I'm no further ahead since my bezel is a mere ring of gold and even if I had a press such as the one in your vid I don't think it would work without special dies.

    • All watches are repairable a few oven duff tools knowledge skills. But I was just agreeing that it be easier to get a movement.
    • First of all, thank you for the pdf file of the book on how to replace a gem. So, if there is a problem with the ruby in the movement, should I buy a new or used movement and replace it? When I watch videos on YouTube of people fixing used watches, I feel like there should be a way to buy a gem. Is there no way to buy it?
    • I suppose @donutdan is not forced to earn his living by repairing watches.  I suppose he does it as a hobby and wants to gain experience, to get better in watchmaking and time is not the issue. Then @donutdan should rather try to repair the damage instead of swap parts from a maybe intact other movement. Swapping parts is not watchmaking. And often swapped parts are not the expected solution of all problems. All mentioned damages are repairable. Frank  
    • Yeah I figured that one out when I googled and realized that my spindle is actually from Horia. It's smooth with no screwable cap.
    • I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.
