You got your watch... now what?

My $.02...
I have local a watchmaker who is both Omega and Rolex certified. He is a graduate of 2 different watchmaking schools, attending the Rolex school in Switzerland in the seventies. He's serviced a number of my reps, and spent a lot of time with me on some very useful education, as I like to tinker. He looks forward to the gen ETA's, hates the 7750's. His opinion: the Asian 7750's are filthy, shipped dry and bound to fail, and parts he orders do not fit on a routine basis. Especially the jewels. They are almost never the correct size. He's asked me not to take him any more. "They're not worth screwing around with".The bottom line, the Swiss ETA's I'm pretty sure any watchmaker outside of an AD will work on. The majority of the watches shipped from Switzerland have ETA movements in them (although a lot are modified to varying extents).The Asian movements you may get some push back on. I often wonder when I read posts that say that this Asian 7750 has been completely serviced. That to me means a complete tear down, cleaning lube and reassembly plus timing and regulation. I doubt it. But, I digress. I think you'll find that ETA movements won't be a problem with most independent WM's.

I haven't yet disassembled one of the chrono movements and probably won't either anytime soon but that is the opinion of most of the people that work on the A7750. They aren't built to the standard of the ETA but if properly looked after they should last.
I'm sure the likes of Rex, Francisco, SpeedyG, Domenico, etc will completely disassemble, clean, oil and reassemble the A7750 without many problems.

Point well taken. There are guys on this and other forums who specialize in the A 7750's. Most independent watchmakers have an aversion to them. Certainly didn't mean to call into question the integrity of the guys you mentioned!
