What happens if, somehow, there were a perfect rep?
And how about the problems with synthetic sapphire sometimes being mineral crystal, while genuine sapphire denotes genuine sapphire? Not much fun when the "synthetic sapphire" crystal gets scratched!
Try getting a cheap watch from narikaa (EU-based) and see if it gets through. It may be cheap enough to use as a test run.
Otherwise give me a ticket out there (from the UK) to visit a pretty Swiss girl and I'll bring them across for you
I have one already but paid around the price you paid just for one of them
And yes it does work. I also tested glass in a window, and also genuine watches with and without AR coat.
Good luck....
2892 is a centre seconds movement as Jonathan said... it would require heavy modification, and I would agree, a 7750 with a power reserve module is what you need.
I'm not 100% sure if they are making a new case or getting an existing case and adapting it.
Only reason I would think for a new case is that it may be cheaper than buying a ready made one that has their own profit built in to the cost.
