Fits better than the OEM.

Added this to my SSK build to use a flat crystal from NAMOKI mods. Absolutely love the quality and fit of this LX bezel, couldn’t be happier with how it looks.

I am very happy with the bezel. It looks so much better than the stock bezel!

I really wanted to put a lumed 24hr ceramic bezel insert on my Seiko GMT, but couldn't find one. They were however available for SKX007 watches, so this bezel solved my problem. I think it looks great. Also, my Seiko Samurai came with a knurled bezel, and I like that very much, so I was happy that Namoki had a knurled bezel that would fit my GMT. I purchased a SKX007 24hr lumed bezel insert from another vendor, and it fit perfectly. I am very happy with how the watch looks with the new bezel and insert.
