The Tudor Black Bay GMT comes with three bracelet options: a riveted steel bracelet, black fabric strap with a red stripe, and the “Terra de Siena” brown leather strap. The steel and leather bracelets, both use a safety folding clasp, while the textile strap comes with a pin buckle.
Inside the Tudor Black Bay GMT is a new in-house movement created especially for the watch: the caliber MT5652. This self winding mechanical movement allows the watch to operate like a “true GMT”. That is, with a jumping local-hour hand, where you can jump the hour hand forward or backward and set your watch to the local time after crossing time zones. Meanwhile, the 24-hour hand remains linked to the home time zone.
The movement is also COSC-certified, comes equipped with a silicon balance spring, and offers 70 hours of power reserve.
