We are here to help
Our Diver One watchmaking kits are now also available with an additional complication - the GMT hand. Allowing you to track two time zones simultaneously, this new movement is a great way to start into the world of additional complications (sophisticated movement functions).
Featuring a classic matte dial with applied, lume filled indices the dial merges seamlessly into the classic case design. Inside the stainless steel diver case the four hand automatic movement (NH-34A) will keep the time as well as the date as well as a second time zone, purely powered by the movement of your wrist. The GMT design is completed by a bi-coloured 24 hour bezel and your choice of strap or 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.
All our kits contain a detailed instruction booklet as well as access to our step-by-step video guides available on our homepage to assist you throughout the assembly.
Our kits are available as Full watchmaking kits or as No tools variants:
- Full watchmaking starter kit includes watch components (case, dial, hands, movement, and strap), a full tool kit (watch hand levers and press, movement cushion, friction ball, cleanroom products, dust blower, Rodico, precision tweezers, table mat, screwdriver (pilot watches only), watchmaker’s loupe and headwire) and detailed instructions (printed booklet in each kit and access to our step-by-step video guides via our homepage)
- No tools kits include only the watch components and the instructions (we recommended to start with a full DIY kit to ensure you have all the right tools for your first assembly)
Safety notice: Please note that these kits are not toys and are unsuitable for children of any age. They contain small parts which can be swallowed as well as sharp tools.
