That's from Gabe's How to Buy a 7002 Diver article. So I guess it's 31mm after all.Librarian1 said:...the two generations use different sized crystals. First generation 7002s use a 32mm diameter crystal, while the second generation models use a 31mm diameter crystal.
Perfect, thanks!7s26b said:The buyers guide is in error - the late 7002 crystal is 31.5mm -same as SKX 0020 case. The early 7002 uses a 32mm crystal -same diameter but different thickness as a 6309.
