Team favorite? Definitely the black dial Humboldt GMT followed closely by any white dial watch we've ever made. You can't go wrong!\nCustom-designed, 20mm tapered matte rubber strap featuring topographic ventilation channels to keep your wrist cool. Our rubber straps will fit a 6.2 inch (158mm) up to an 8.7 inch (220mm) wrist. The strap is 130mm / 75mm in length, without the buckle.\nOverview\n\n\n\n\n\nEach 20mm strap is tapered and includes an 18mm stainless steel buckle with a tang that is engineered to sit level with the buckle. The buckle is signed on both the top and bottom and has a grooved channel on the underside to allow the strap to sit more flush and comfortably on the wrist.    \n\n\n\n\nFREE SHIPPING FOR DOMESTIC ORDERS! \n* International buyers are responsible for any customs duties.\n\n","images":["https://cdn.shopify.com/s/files/1/0261/8002/6421/files/OO_04012023_Straps_0311.jpg?v=1712176136","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/OO_04012023_Straps_071.jpg?v=1712178543","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/OO_04012023_Straps_077.jpg?v=1712178550","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/CB_01222024_174.jpg?v=1712178562","https://cdn.shopify.com/s/files/1/0261/8002/6421/files/CB_01222024_269.jpg?v=1712178570"],"price":85,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:43.322Z"},"share_url":"https://firestarter.network/l/lst_qrhSQVXY","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
