Shinola 40MM White Stainless Steel Watch. First developed for commercial airline pilots in the 1950’s, GMT watches are the perfect traveler’s companion. The 40mm Shinola Monster GMT automatic watch features a fourth hand that rotates once every 24 hours—meaning the wearer can check against the ceramic bezel marks to track time in multiple time zones. A sapphire crystal case back window reveals the complex inner workings of the Sellita SW330-2 movement inside. An additional #tide® ocean bound plastic woven strap releases easily for on-the-go swapping with the innovative quick-release stainless steel bracelet. Crafted from stainless steel and rated at 10 ATM, this travel watch is fit for both land and sea.
