An Elegant and Robust SKX mod case

I paired this exquisite case with the MM300 coin-edged bezel, Tuna Solar Style insert, double domed sapphire crystal, Seamaster black dial and sword hands to homage the original Semaster 300’s - the build is my favourite watch of all time. The parts are very well finished and expertly packaged. Pricing for the European customer is inclusive of shipping and VAT and shipping is fast (less than one week)! What an amazing build. You can watch the video of the build here: https://youtu.be/5Kg67uI1JNQ. Keep up the good work Namoki

NMK930 Nautical w Crown Guard SKXSPRD Watch Case

This case feels VERY solid. I'm excited about this watch being a super strong daily wearer. The only difficult aspect of the build we cutting the stem to fit the integrated crown. Once I got that done everything worked perfectly. I really like this case a lot.

Best MM300 case Available

I've purchased quite a few MarineMaster style cases in the last year and a half. Couple from Namoki, one each from CrystalTimes and Watch and Style. All are great cases in their own right. However, Namoki's steel MM300 was my favorite. I had always thought about picking up the titanium version when they released it. The price kept me away. What finally sold me on it was the different finishing and increased durability.

So far I'm very happy with the case. I've made about 10+ mods since February 2021. It's a pricey hobby. I told myself if I ever found a genuine blue marine master dial, I'd drop the money on the Titanium case - kinda like an ultimate personal build. Go out with a bang kinda thing. That's exactly what I did. Honestly though - it's my favorite watch and the one that consistently gets the most use. Thanks Namoki!
