Whats the differnce in the case...

[Dizzy]

So whats the difference between a Yuki 5510 case and a Yuki 6538 case?

Are they the same other than the 5510 takes a cal.1570 and a 6538 takes a cal.1030??

If i was going to use a Yuki case with an ETA movement, should I get the 5510 because movement adapters for the 1570 to ETA are readily avail? What ETA do you need to put into a case made for a rolex cal.1030?

Actually the 5510 takes a 1530 movement which is earlier than the 1570 and beats at 18,000bph as opposed to the 19800bph for the 1570- 1570 is also chronometer grade, only a few 1530's were certified chronometer grade.

I would think you could put a 2824-2 with a movement ring in a 5510 case. If that didn't work, maybe a 2836-2/2846-2 would do the trick. As for a 6538, I have no idea, maybe you could ask Yuki.
