  • 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.
