We are here to help
Building an automatic watch is a challenging task, but with our complete sets you will receive the prepared components for assembly, a full tool kit and detailed step by step instructions. All you need is a steady set of hands and a bit of patience, to complete this kit!
The D1 GMT is a GMT diver watch with an NH-34A automatic watch movement. Inside the 41mm stainless steel case, you will find an easy-to-read diver dial with date window and silver polished hands with the additional coloured GMT hand to track a second time zone. Hour markers and hands are filled with extra strong lume to increase legibility in low-light environments. The watch comes either with a fully water resistant, soft and comfortable FKM strap or a stainless-steel bracelet.
Containing all parts, tools and instructions our kits are an ideal start into the world of horology. Learn more about the way a watch ticks, the origins of watchmaking and how to assemble your own automatic watch at home.
