it'll be interesting to know what movement is inside this 7928. As Snowflake hands only came on the 7016 & 7021 ref onwards, which had an ETA movement. From what i recall, the 7928 was a cal 390, and there was never any snowflake hands configuration, so I'd be surprised to learn that 7928 cal 390 would have SF hands to fit during service replacement. I could be dead wrong, but I'm rather skeptical about having SF hands on a 7928.
