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!

Nice case

A nice smaller 62MAS style case for more authentic vintage style builds.

Great case from Namoki!

Fit and finish is gray making the assembly process go smoothly. This results in a great finished product.

Having looked at a few options for one of my designs I think this has to be the best case I have handled. The finishing is excellent with a nice mix of brushed and polish. Great work guys! Thank you, Dan
