Interchangeable Casebacks?
I know this has been asked once before, but I was really curious to know whether the casebacks of a Submariner Ceramic 116610 and a GMT IIC 116710 are interchangeable?

They both have the same case size so I don't see why not? But I'm no expert.

The Sub case-back is almost half again as thickas the GMT, and the back of the Sub case is machined flatter while the GMT IIc is recessed slightly and so fits flatter on the wrist..

Why would anyone want to swap casebacks?

But if the extra thickness is also on the inside of the Sub's caseback, and this was to be screwed to the GMT's case, the gap between the 3186 rotor and the caseback would reduce. Then, is it not possible that the GMT II 3186's rotor would touch the caseback? Given the varying heights of both GMT's and Sub's cases, I am guessing (experts, please correct me!) that the Sub's case compensates for this caseback thickness in some way... |

Since most of the other things such as the crystal thickness, triplock-crown and probably the gaskets are the same across the GMT IIC and the Sub C, the only thing that allows the Sub to withstand greater water pressure is its extra thick caseback. So I was wondering whether it is actually possible to make the GMT IIC more water resistant by swapping a Sub's caseback onto it...

i would probably just swap the Sub for the GMT? seriously, do you have occasions to need greater diving depths?

The caseback is integral to water resistance and pressure. The Sub is indeed much thicker

However, at 100 meters, the GMT is already more waterproof than any person wearing one can physically free or scuba dive to..

Thanks guys for all the replies!
Absolutely agree to this!! That's why I have always felt that the GMT II and Explorer II are amongst the most versatile rolexes out there! |
