Rolex Sub 116610 & Explorer II 266570 - Two Questions
Hi,
Why do water resistance ratings for the current Sub (300m) and Explorer II (100m) differ? I know the Sub has a Triplock Crown and the Explorer only has a double-lock crown, but is that the only reason for the different ratings? Or is there something else (case construction, perhaps) that contributes to that difference?
Also, apart from the GMT function on the Explorer II, are the underlying movements fundamentally the same?
Thanks.....
