When the modern version of the Tudor Black Bay was launched in 2016, it had a burgundy bezel and a 41 mm case. After several iterations since then, the newest model revisits the iconic burgundy bezel and case proportions, but there is one big difference: it contains an evolved, elite movement that is tested according to METAS
Master Chronometer certification standards. In order to qualify, a watch must be able to function within a 5-second range of variation each day (0 /+5), that is to say 5 seconds less than the Swiss Official Chronometer Testing Institute (COSC) (-4 /+6) carried out on a single movement. Also, it must guarantee that accuracy in the presence of magnetic fields
of up to 15,000 gauss. The caliber MT5602-U meets all these criteria and has a power reserve of 70 hours. Another modern touch on this vintage-style watch is the Tudor T-fit clasp on its rubber strap or steel bracelet, which is equipped with a system for rapid length adjustment in five positions.
