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 (use our NMK926 Solid End Link for it to fit our SKX013 bracelets). Build your very own dream baby 62MAS mod with the NMK927 62MAS SKX013 Watch Case today!

An Excellent Case for Almost Any Build (NMK931)

This is an excellent case that's versatile enough to work with a lot of different build styles, and its easy to use since the crystal is already installed and you don't need a chapter ring. The overall proportions and finishing are just excellent (especially the delineation between the brushed top of the bezel and the polished chamfer). I was using a Lucius Atelier Grand Seiko 39mm case before, but I like this NMK931 a lot better. My only complaint is that the fit between the case and movement holder is reeeeally tight, so tight that I don't think I could get the movement out without breaking something.
