I'll try and show what I mean... Oh it worked. See,in the upper photo which I think is the 145.022, the sub-dials are obviously saucer shaped with a chamfer going down from the OD to the flat of the face, whereas in the lower image, 3570.50.00 the sub-dials seem to be flat and just a bit lower than the face of the main dial. Borrowed these photos from Fratellowatches.com (top) and Watchfinder.com
Anyway, it's a bit academic now as I've decided to buy new or virtually new, possibly from Swisswatchesdirect.co.uk as there seems to be so much of a minefield out there on vintage watches and, as I say, I'm not a collector, I just want another great watch.
