My FXD rep has seen the pool, lake, and snow. Soon it will be in the ocean. (Passed 10 bar after confirming the case back was properly sealed tight.)
Most of the diver reps I’ve personally tested… pass to 6-8 bar from the factories (if you make sure the case back and crown are on tight). A majority of case backs aren’t shipped overly flush and tight from QC checks.
My theory is that’s why so many on the forums are sure a rep can’t swim. VSF/Clean/ZF/M+F and ARF have been able to pass 8 bar up to 12 bar. I do place a slight coat of silicone gasket grease to the case back o-ring when they arrive.
