Movement spacer ring was missing from kit

I just got my Diver40 kit and the movement spacer ring was missing. Also the video said the movement was either a 8N24 or a 82S0 movement, but my movement is stamped NH72A.

Hi @sean1722, I can confirm that NH72 is the correct movement for the Diver 40 series. The video that introduces the movement uses another movement to illustrate the function and handling of mechanical movement, and those are common among most mechanical movement.

Regarding the spacer ring, could you send me an email at so my team can assist you there?
