Finding the "correct" crystal for an Omega C 2576-7

This is an ongoing project for me. I have just replaced the hands and dial on this watch, as well as servicing and replacing some damaged internal parts.

When I got the watch, it had a very poorly fitted crystal that dropped out with very little pressure from the inside.

I have installed a generic crystal that is nice and snug so it is working for now. But I would love to find the right NOS crystal for it. Ebay has many listings for crystals, with the diameter listed, and usually Omega part numbers form the paper envelope, but I am currently lacking the research knowledge to figure out what the correct part number would be.

I know I need a 29.6mm crystal with a silver ("white") tension ring, or at least I am reasonable sure that is correct. 

I have found images of the parts breakdown for the movement parts but nothin similar for the case.

Can anyone point me to a good reference for the case parts?

If you go to cousins battery on the case number in the document search you'll get the PDF I have attached

Cousins says part number PX5000. But that’s a gold ring type,

Based on the PDF your number is more or less correct you just have to change one of letters. Then it looks like there's a seller on eBay  not cheap of Although cheaper than what Omega would sell it to you for

63PZ5000  GLASS PLEXI ST RING D29.62 H4.3

      There is one Oris there at least, and if you could get a Unicorn for this price!??! 😄 It says that they don't work though, you might need to figure out what a Unicorn eats then. 😉

      Rolex Cal 1570 Balance wheel rubbing

      By Jon · Posted

      Here's a quick Gif I made to show truing the balance using callipers. This has such a slight wobble, but is within acceptable parameters. The important thing is the balance doesn't touch or rub anything when in operation. This is an Eterna Tank. Here's a pic of the balance freshly rivetted with a new staff in the movement

      I just poked an inflation calculator, and $5 in 2020 would be about $6 in 2024. Doesn't fit very neatly into any status codes, which stop at 5XX, but that's honestly somewhat arbitrary outside of a clever pun for those that dabble in such things. Back during the pandemic, I would spend a good chunk of idle time in the evenings scanning through hundreds of listings a night, and I would only land 1-2 a week max. I would often go months without finding something suitable. A very small percentage of the watches in the price range are worth pulling the trigger on for my purposes. The number floating through the thread here may be somewhat deceptive.

      Balance cock stud screw

      By Zedster · Posted

      Hi, guys I got there in the end after several attempts using a screwdriver and Rodico, I couldn't wait for the tool to arrive and was getting pretty confident handling the stud screw without it flying away. At first, I was using far too much Rodico, and then realized you only need the smallest amount inside the screw slot. Putting the cock back onto the movement also helped as it gave me more to hold onto while my shaky hand tried to align the screw wobbling away at the end of the screwdriver😁 Anyway, job done and I can move on. Thanks again for all the advice it's really appreciated for a beginner.
