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.
Combining a GMT movement with 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 and 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 available with either a flexible and soft 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.
