*** 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 7 different SKX007 bezels in the hope that you may consider purchasing your bezel from us.
