DIY Vintage Dive Watch Kit | 40mm Diver with Sapphire Crystal & CTS FKM Rubber Strap, tools and full video guide
Meet the sapphire version of our 40mm Vintage Diver.
The case is inspired by classic vintage divers like the Rolex 5512/5513. At 40mm with a slightly slimmer case body, it sits nicely on most wrists.
This time we've fitted it with a sapphire crystal. You still get that vintage diver look, but the crystal is much more scratch resistant, so it's easier to wear every day without worrying. The screw-down crown helps keep everything nicely sealed too.
It comes on our CTS FKM rubber strap. It's cut-to-size, so you can trim it for a fit that feels just right, and it closes with a push-button butterfly clasp. FKM rubber is soft, comfortable and happy around water.
Flip it over and the exhibition case back shows off the TMI movement you've put in yourself. Choose NH35 or NH70.
Everything you need is in the box: the parts, the tools and our step-by-step video instructions. Take your time and enjoy the build :)
