New here (well been lurking on and off for years) - picked up a nice 6138-0017 chrono a few years ago for next to nothing in a thrift store and finally getting around to restoring it. It needs a new bezel, crystal, possibly pusher springs, and who knows what else. Finally found a good and qualified watch repair guy in So Florida but I need to source parts. I found the bezel but not sure on which replacement crystal to get. Any suggestions on the various various replacement crystals available on eBay? Any better vendor? What about a Sternkreuz?

Also any other sources for parts?

Appreciate any guidance or suggestions offered. Don't have a pic to share right now but will when it's all done.

Thanks - Adam
