The smallest sub dive watch case on the market!!

Fit a bezel insert and this piece will look huge on a wrist.

Now in DLC BLACK EDITION!! The god tier coating in the market.

What is DLC?
Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. As the name suggests, diamond-like-carbon means that the layer is as scratch-resistant as diamonds. DLC coating has 5 times the hardness of a 316L stainless steel. With DLC being harder than steel, this means that a DLC coated watch will have a very high resistance to scratches that you will not have to worry about scratching your watch. This coating will not disappear if you accidentally do something that would otherwise leave a huge mark on some PVD-method coated watches. A feature that is highly coveted by many watch enthusiasts.

Originally designed after a vintage Rolex Submariner 5513 with drilled through lugs and slightly pointed crown guard with a unique small 36mm size and is GMT NH34 Movement READY!!
