we are here to help
A rough, brushed case carved out of stainless steel and completed by a sapphire crystal and screw down crown - no fuss, no games. A true tool watch ready for everyday wear above and below water.
This watch is comprising our Voyager GMT dial and GMT hands (both lume filled and silver polished), powered by the NH-34A automatic GMT movement made in Japan. To maximise suitability for any situation, the GMT Toolwatch is equipped with an FKM/Sailcloth hybrid strap. Utterly resistant to water and easy to clean, while the sailcloth top layer ensures a modern, but not too sporty look.
This watch is ideal for anyone who likes the durability of a diver watch, but prefers to skip the rotating bezel in favour of a sleeker, cleaner design.
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 (click here for an example) 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.
