OMEGA Chronostop Dial Screw Alternatives

Hello all,

I recently recieved an Omega Chronostop Geneve Driver from my grandfather that got damaged by a bad repair service (supposed to be a crystal replacement but the "watchmaker" had a mind of his own). I've been steadily working on getting it back into order (repairing bent and delumed hands, new gaskets, missing parts), however I've struggled to find a dial screw for the Cal. 865 that is housed inside. I've tried ordering new/old stock, but have had no luck in finding one that fits. Are there any tried and true methods that will secure the dial without messing up the movement or are there any individuals willing to sell a Cal. 865 dial screw? This is a special timepiece and I want to do the best possible job to get it back I order.Thank you all in advanced for your help.

Photo of the watch (before working on it) below for reference.

I ordered a set off of ebay and it didn't fit. I will try again to see if the movement plate's threads were just stripped from the previous "repair" or if I need to reorder from another seller. I saw mixed input from people using dial dots and was wondering if any other alternatives were available that I missed. Thank you so much for your help!

Did you compare the ones you got to any still in the movement?

I've found on the rare occasion. If someone didn't have the right screw. Closest wrong one would be used. Usually damaging the threads and rendering an original screw useless.

Might need to re-tap next size up and find a replacement screw to fit

Don,

Thank you so much for the tip; I will definitely take another look at the screw hole as I continue to work on getting the dial secure. The original screws I ordered looked too big after I took a look at the head compared to the screw already in the movement, and the finishes are completely different. I have another screw coming in that looks closer to the one in the movement and is marked as part #2236 (thank you @Archer for the part reference). Hopefully this one works and if not, I may have to get it re-tapped. If that is the case, I may take the watch to someone that already has the tools to do so as the budget to fix this has been continually increasing. Thanks again and I'll post a finished photo once everything is put back together. Boy does this watch have a story to tell!

Once again, the screws were too big. After some more research I found that I had the Calibre 920 housed in my Chronostop as the 920 had the date wheel that the 865 did not. I have the correct screws coming in and will have the dial firmly secured in a few days. Unfortunately the canon pinion is loose so the entire movement may have to be disassembled...

Thank you all for your help!
