THE DIVER ONE GMT
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.
