Since it was introduced in 2012, Tudor’s Black Bay has become not just one of the watchmaker’s most successful models, but also one of the most coveted timepieces on the market. A diver’s watch with an elegant retro aesthetic, it combines the best of classic styling with the very latest in watchmaking innovation. Inspired by the appearance of the dials of Tudor diving watches from as long ago as the 1950s, including the unmistakable “snowflake” hands, it is distinctly modern in its accuracy, its robustness and the sophistication of its movement, powering all sorts of sought-after horological complications. One such complication is available on the dial of the new Black Bay Pro, introduced at this year’s Watches and Wonders – a piece that also represents a daring aesthetic overhaul of this much loved line. Tudor has long been the watchmaker of choice for the most adventurous among us, valued for its timepieces’ accuracy, robustness and reliability. That tradition dates back to when brand founder Hans Wilsdorf personally supplied watches to the 30 members of the British North Greenland Expedition in the early 1950s, and the rugged Black Bay Pro takes its inspiration from those pioneering explorers and the timepieces they wore. STYLE Edit: Mark International Women’s Day with Tudor’s Clair de Rose watches Its most immediately striking feature is the 24-hour graduated satin-brushed fixed bezel. But the watch is as smart as it is beautiful, with the MT5652 manufacture calibre featuring built-in GMT function at its heart. A yellow 24-hour snowflake hand, with Super-LumiNova applied to it, shows the reference time, with a shorter snowflake hand indicating the local time. The applied hour markers on the dial are made from monobloc luminous ceramic for the first time. The watch comes in a 39mm case, with a redesigned crown set flush to the middle case band for maximum grip. STYLE Edit: How the new Tudor Pelagos FXD marks a historic collaboration Also unveiled at Watches & Wonders this year was another coveted model from the collection with the same complication, the Black Bay GMT, given a warm, romantic new appearance in the form of the Black Bay GMT S&G. Those letters stand for “steel and gold”, and the timepieces come wrapped in a satin-brushed, polished 41mm case crafted in a winning combination of 316L stainless steel and yellow gold. This version of the Black Bay comes adorned with the bidirectional rotating bezel typical of diver’s watches , in black and brown anodised aluminium, with the two colours representing day and night, offset by yellow gold. Again it is powered by the MT5652 manufacture calibre, which here offers three time zones from its GMT complication, and again it deploys the trademark snowflake hands coated with Super-LumiNova to indicate the different time zones. STYLE Edit: Tudor celebrates 50 years with the new Black Bay Chrono Both the Black Bay Pro and the Black Bay GMT S&G come with a particularly ingenious feature in which the date function and local time hand work together in harmony, with the date instantly jumping back a day when the time hand is wound backwards beyond midnight. Both are also offered in a choice of a steel bracelet, a leather strap or the brand’s signature jacquard woven strap. Want more stories like this?
