You have to use a combination of judgement, a vernier gauge, and a little trial and error, even experience professionals often order in more than one glass for any given replacement.
I'd be very impressed if anyone knew offhand the right size crystal for this watch. 

Do you have a crystal lift?

Also it does not look broken to me, worn and scratched, unless the crystal is loose? but polywatch and cotton could fix most cosmetic wear to acrylic crystals.

Welcome the forum. Looking at the pictures of your watch, the crystal only looks scratched. If this is the case, you can remove the scratches with 800 then 1000 grit wet or dry paper used by car paint finishers. Once you have rubbed out the scratches, finish off the job with a good quality metal polish such as Solvol Autosol.

Do not rush the job and take great care not to rub the case with the abrasive paper during in the process.

Thanks for comments. By the way these pictures are old and before the crystal got broken. I just wanted to show you the exact type of the watch. I have already bought a 27.8 mm crystal but I am not sure that's the correct one or not. So I wonder 27.6 mm or 27.8 mm fits. post-942-0-42974200-1429704022_thumb.jpgpost-942-0-90498100-1429704581_thumb.jpg

Ah I see your problem.

Using vernier callipers measure the diameter of the broken one. Order two new ones, one the same size or 0.01mm larger, and also order the next incremental size up. One of them will fit, but you will need to have a crystal lift to compress the new crystal to allow it to enter the case.

      About repair watch's jewel.

      By jhoho202 · Posted

      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?

      Parts sourcing for FHF 180 movement

      By praezis · Posted

      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.

      Parts sourcing for FHF 180 movement

      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.

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.
