  • *This case was tested to 300M during development and subsequent testing of actual production cases – no failures were recorded.
  • Suitability
  • A great basis for a custom build – a mass of SKX007 aftermarket mod parts are available for you to build your DREAM MOD
  • INFO – Crown stem length same as SXK007 OEM with 0020 case
  • **Drilled Through Lugs for easy bracelet and strap changes reducing the risk of scratching/damaging your case
  • *** We can pretty much guarantee 100% our CT manufactured parts and Seiko OEM SKX007 parts will fit. Most reputable aftermarket manufacturers parts will also be ok, but we cannot 100% guarantee this as in some instance’s tolerance build up/variation exists that can be problematic – bezels being a particular area that can be tricky. We now have many different SKX007 bezels in the hope that you may consider purchasing your bezel from us.
  • Additional info – Ideal for building a complete custom 1 off mod


  • Hi Polish/Brushed as oem 0020 case
