Jack Mason is a well known name in the watch making business and have been since their start in 2013. In those four years, they never offered a dive watch, something their customers have been asking for almost since day 1. But now they’re remedying that with the JM-D103. It’s completely stainless steel, with a reliable Japanese automatic movement and the ability to withstand 30 ATM, all with a rotating bezel so you know exactly how much air you have left in your tank. It can stand up to pretty much all recreational diving and a great deal of professional diving, while also looking good enough to round out your best suit on a formal night out. The JM-D103 is a versatile watch that will stick with you through all your undersea and overland adventures.
