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. \nPowering 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. \nOur 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).\n\n\n\n\n\n\nSpecifications\n \n\n\nSellita 330 automatic 25 jewel mechanical Swiss movement\n\n\nAnti-magnetic enclosure\n\n\nAnti-shock bumper technology\n\n\n56-hour power reserve\n\n\n28,800 bph / 4 Hz\n\n\n316L Stainless steel\n\n\n39.5mm case diameter with 40.0mm bezel\n\n\n24-hour, 120 click bi-directional black pvd bezel with ceramic ball bearings\n\n\n20 ATM water resistance (200 me","images":["https://cdn.shopify.com/s/files/1/0261/8002/6421/files/HumboldtNoir_0687Sunrise1-2048.jpg?v=1783648142","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/HumboldtNoir_0766Records-2048.jpg?v=1783648144","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/HumboldtNoir_0854Caseback-2048.jpg?v=1783648146"],"price":2350,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-10T03:59:28.973Z"},"share_url":"https://firestarter.network/l/lst_nkm76Kpv","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
