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, a GMT movement is a great way to start into the world of complications.
Featuring a sun-ray brushed dial with lume printed indices and a worldtimer bezel, this kit allows you to keep an overview on all different timezones - a perfect companion for travel! The dial is accompanied by a set of silver polished hands and a black, white fourth hand for the GMT timezone. Inside the stainless steel diver case the automatic movement will keep the time, the date as well as a second time zone, purely powered by the movement of your wrist. This kit is completed your choice of sportive FKM strap or 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.
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.
