Available on our fully articulated stainless steel bracelet with quick-adjust clasp. Overview   The anti-fragile, anti-worry, go anywhere and do anything watch. Swiss-powered, anti-shock, anti-magnetic, GMT function all in a brushed stainless steel 40mm case with a bi-directional bezel and 20ATM water resistance. Built to Discover.  Powering the Humboldt GMT is the Swiss-made Sellita SW330, a rugged and reliable movement that combines time-tested dependability and remarkable accuracy. A quick-set adjustment allows you to independently set the 24-hour hand to simultaneously track multiple time zones. With a power reserve of 56 hours, quick-set date, 25 jewels and our iconic 4-star rotor all tucked in securely behind a protective solid caseback, we’re confident this movement will live up to the demands of the Humboldt GMT Owner.  Our stainless steel bracelet sits comfortably on the wrist with a fully articulated link design that gradually tapers from the 20mm solid end links to the 16mm buckle. The bracelet has 7 removable links and a six position quick-adjust, locking clasp. Yup, that means no tools required to adjust the fit on the fly! The bracelet will fit wrists from 6.3 inches to 9.1 inches (160mm - 231mm).
