CASE BACKS IMPORTANT NOTECT231 or CT239B with built in spacer are for use with NH35/36 movements with thinner grey movement holder – no need to do anything the movement can drop straight in. If you are using a movement with the thicker black spacer you MUST use an oem case back or our CT200 or CT239A

Dimensions – The same dimensions as the SKX007 0020 case – 22mm lug width, lug to lug dimension, thickness, width, height all as SKX007.Moving the crown guard to 3 adds nothing to the width.

**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
