The Black Bay GMT is instantly recognisable by its 24-hour graduated rotating bezel with two colours: deep blue and burgundy or in brown and black for its steel & gold version. The Black Bay GMT features a 41mm satin-brushed steel case, which is waterproof to 200m (663ft). Luminescent hour markers are set against its dial to ensure legibility at night ? and in all conditions. The TUDOR Black Bay GMT sports an incredibly useful multiple time-zone complication ? also known as a GMT function ? that establishes local time without losing sight of the time in two other time zones.

TUDOR has added an all-new opaline dial that perfectly complements the iconic colour scheme of the Black Bay GMT, in addition to the existing Black Bay GMT with a black dial and Black Bay GMT S&G. The Balck Bay GMT is available with a stainless-steelbracelet inspired by the folding riveted bracelets made by TUDOR in the 1950s and 1963s or a black strap with a woven burgundy accent matching the bezel. The Black Bay GMT S&G version comes with a choice of a riveted steel and gold bracelet, a ?Terra di Siena? brown leather strap with folding clasp and safety catch, or a black fabric strap with a beige band.
