The famous Black Bay family introduced the first TUDOR chronograph, powered by the self-winding Manufacture Calibre MT5813, with a column wheel and vertical clutch. This model is now available in an S&G version.
COLUMN WHEELAND VERTICAL CLUTCH
Since the presentation in 1970 of the Oysterdate Chronograph, its first chronograph, TUDOR has always produced watches that are closely tied to the world of motorsports. In the same way, since 1954 TUDOR has been constantly improving its professional divers’ watches. The new hybrid Black Bay Chrono chronograph dares to combine the aquatic heritage represented by the Black Bay family with the queen of the racetrack, the chronograph.
ENGRAVED TACHYMETRIC SCALE
Remaining faithful to the Black Bay aesthetic with the famous snowflake hands –a brand signature since 1969– the Black Bay Chrono model offers optimum readability against the domed matt black dial.
Its sub-counters are hollowed for optimum contrast and a date aperture is positioned at 6 o’clock. The recognisable characteristics of the Black Bay are preserved in a steel case with a 41-millimetre diameter, fitted with pushers inspired by the first generation of TUDOR chronographs. A fixed bezel in circular satin-brushed steel with engraved tachymetric scale completes this sporty new chronograph.
THE MANUFACTURE CHRONOGRAPHCALIBRE MT5813
Boasting a 70-hour power reserve, a silicon balance spring and certification by the Swiss Official Chronometer Testing Institute, the Manufacture chronograph Calibre MT5813 that drives the Black Bay Chrono model is a high-performance movement. Crafted in the purest watchmaking tradition, it features a column wheel mechanism and vertical clutch. In keeping with the TUDOR philosophy of quality, it presents extraordinary robustness and reliability, guaranteed by an array of extreme tests applied to all TUDOR products.
A RIVETED BRACELET,
A LEATHER STRAP,
OR A WOVEN DENIM-STYLE FABRIC STRAP
The bracelet of the Black Bay Chrono is inspired by the folding riveted bracelets of the TUDOR watches produced in the 1950s and 1960s, which were famous for having the heads of the rivets attaching the links visible on the side of the bracelet. The links also had a distinct stepped construction. These aesthetic details are incorporated into the bracelet of the Black Bay Chrono, integrating modern manufacturing methods using solid links. The watch is also available on a rich brown leather strap with folding clasp.
The fabric strap is one of TUDOR’s signature features. Woven on 19th century Jacquard looms by a 150-year-old family firm from the region of St-Etienne, its manufacturing quality and comfort on the wrist are unique. The Black Bay Chrono model is available with a navy-blue denim-style strap designed by TUDOR.
The history of the TUDOR divers’ watch dates back to 1954 and the launch of reference 7922. The first in a long line of ergonomic, legible, accurate and robust divers’ watches, it perfectly embodies the approach formulated by the American architect Louis Sullivan, according to whom the form of an object must follow its function. Furthermore, it laid down the aesthetic and technical foundations of an ideal divers’ watch, those of an understated, functional and reliable tool. The sixty years that followed the launch of the original 7922 saw the constant improvement of the TUDOR divers’ watch and each model gained unanimous acclaim from professionals in the field, including some of the greatest military navies in the world.
