Introducing the NMK908 MM300 SKX Conversion Case. Inspired by the immensely popular MarineMaster, the NMK908 MM300 SKX007/SRPD Watch Case in Polished Finish is finished brilliantly with a combination of brushed and polished sides and lugs giving it a distinctive, handsome look. It is definitely one of our favourite case shapes!

It has been designed to fit all OEM and aftermarket SKX007 parts except the bracelet (it will fit MM300 bracelets) and its standard SKX caseback design makes it real easy to assemble.....and mod, over and over!

Pair it with one of our MM300 bezel and it'll make for a great base MM300 homage project.
