The Heritage Black Bay Chrono was, for me, an unexpected watch to say the least. Described by Tudor as a hybrid chronograph, it brings together the aquatic heritage of the Black Bay family with the brand’s long-standing association with the racetrack.
The Heritage Black Bay Chrono
The Heritage Black Bay Chrono is offered in the same 41mm steel case as other models in the collection, with a polished and satin finish and comes fitted on your choice of a steel bracelet or a leather strap. As you might expect, the uni-directional rotating bezel found on the other dive watches in the collection has been replaced with a fixed bezel in circular satin-brushed steel, complete with an engraved tachymetric scale.
Ignoring the chronograph for the moment however, it is clear that the Heritage Black Bay Chrono has been designed specifically for the Black Bay family. It features all the hallmarks of the collection, including the iconic snowflake hands, an over-sized screw down crown complete with Tudor rose engraved and lacquered in black and a high-contrast dial for optimum readability in all conditions.
Even the twin sub-dials have been made slightly concave to add depth to the dial and further improve legibility. At three o’clock there’s a 45-minute counter for the chronograph, whilst the sub-dial at nine o’clock is for small seconds. The date is shown in a window at six o’clock, just beneath the 200m water-depth rating in red, which is a subtle nod to Tudor’s vintage dive models.
To start, stop and reset the chronograph on the Heritage Black Bay Chrono, you simply use the fluted, screw-down pushers found on the side of the case at two and four o’clock, the design of which has been inspired by the first generation of Tudor chronographs.
Hybrid aesthetics aside however, it’s the movement inside the Heritage Black Bay Chrono that really got chins wagging at Baselworld. Denoted by Tudor as the Manufacture chronograph Calibre MT5813, it was actually developed and manufactured for Tudor by Breitling and is based on Breitling’s main chronograph movement, the B01 (something that Tudor was very honest and vocal about at the Fair). It features Tudor’s proprietary adjustable moment of inertia balance wheel, hairspring, and finishes. Certified as a chronometer by the Swiss Official Chronometer Testing Institute, it boasts a silicon balance spring, a column-wheel chronograph mechanism with vertical clutch and offers a max power reserve of 70 hours.
As previously mentioned, the Tudor Heritage Black Bay Chrono is available on your choice of either a tan leather strap or steel bracelet with riveted links, with both versions also coming equipped with fabric strap for more casual wear. Pricing is set at CHF$4,500 with the strap and CHF$4,800 with the bracelet.
