NMK308 - SKX/SRPD Slim Domed Sapphire Crystal for Sloped Inserts (NH34 Compatible)


AR Color

We all know how much of a chonky boy the SKX is and over here at namokiMODS we’re a little obsessed with making it as slim and sleek as possible so we designed a range of Slim Bezels and Crystals to shave off some much needed extra pounds off the SKX007/SRPD.

This NMK308 SKX007/SRPD Slim Domed Sapphire Crystal is designed to be installed with our SKX007 Slim Bezels and a sloped bezel insert to give you the slimmest SKX mod possible.

Paired with a sloped bezel insert, our Slim Domed Crystal and Caseback, you can have a SKX007 build that comes in at a thickness of 12.6mm, much slimmer than the stock SKX007 that’s 13.3mm thick. Check out our Slim Line collection for all our slim parts!

Parts Compatibility:
Movement: Compatible with NH35/36/70/71 etc and NH34 movements for GMT builds.

Crystal Gasket: The NMK308 requires a custom crystal gasket size which is supplied with the crystal - Select either the SKX007 or SRPD option accordingly for the correct crystal gasket size. Need more? Simply select the appropriate gasket under Add-Ons above!

Hard to install

Kinda hard to install, probably because of different gasket. Maybe skill issue on my end.

Slim sapphire doesn't even fit

The only mod part which was totally useless was this slim sapphire which doesn't even fit. While the stock oem hardlex was perfect in it's dimensions the namoki slim sapphire was small, to make things worse the gasket provided was too big to even fit into the case. Thinking they gave me the wrong gasket I ordered another 3 piece srpd gasket for the slim sapphire and it was the same story. The gasket being too big to fit into the case and with slim sapphire too small. It would one those reasons or the combination of both which make the slim sapphire unusable for me. I had to use the use the stock hardlex just to complete the mod but it doesn't look with the upgraded slim bezel and slope insert.
