The NMK927 62MAS SKX013 Conversion Case is our take on the grandfather of all Seiko dive watches, Seiko's first professional dive watch launched in 1965 - reference number 6217-8000 or more fondly known in the collecting community as the 62MAS. It's taken on a cult status in recent years, with Seiko launching multiple reissues and it still has a look that's as sharp and sleek in 1965 as it does today.

We've designed this case to be compatible with all SKX013 parts (except the bracelet because of the lug design, but the 62MAS is better on a rubber strap anyways!). Build your very own dream baby 62MAS mod with the NMK927 62MAS SKX013 Watch Case today!
