The best quality fake Tudor Heritage Black Bay Chronograph profits from a collaboration with Breitling while drawing deeply from Tudor’s own history. In this feature from the WatchTime archives, with original photos by OK-Photography, we give the watch an in-depth review.
Our photographer appreciates high-quality products that have a story to tell – like his Leica camera that’s been around since 1954, attached to a leather strap from Cyprus that has a unique, well-worn patina. As he’s staging the copy Tudor Heritage Black Bay Chrono for our photo shoot for this review, it occurs to him that he prefers classic objects with no “sell-by date.”
Tudor draws characteristic elements of this watch from models in its past. The curved sapphire crystal and dial recall the first Tudor dive watch. The oversize “Big Crown” is a design feature of the Reference 7924 from 1958, the first Tudor replica wristwatch to be water-resistant to a depth of 200 meters. The water resistance is printed in red on the dial of this watch, just as it was on historical models. And the new model’s “snowflake” hands are like those on the Tudor wristwatches that were supplied to the French Navy in the 1970s. History also connects the new fake Tudor Heritage Black Bay Chrono Ref. 79350 with the world of motorsports – represented here by the chronograph with its fixed tachymeter bezel, which has been a feature of all Tudor stopwatches. Tudor introduced its first chronograph, the “Prince Oysterdate,” equipped with an ETA/Valjoux 7734 movement, in 1970.
This new model’s movement is the result of a collaboration with Breitling. The two brands are now sharing expertise in the design and production of mechanical movements with the aim of developing more in-house capabilities. Using Breitling Caliber B01 as a base, Tudor has installed an in-house regulator with a silicon hairspring – a joint patent of Rolex, Patek Philippe and the Swatch Group – and then placed its own rotor on top. Tudor calls it the MT5813 caliber and it has been certified by the COSC as a chronometer. (In turn, Breitling is using Tudor’s MT5612 caliber as a base movement.)
Tudor clone has made another technical modification to the original base movement. Like its first chronograph, the subdial at 3 o’clock has a 45-minute range instead of the usual 30 minutes.
The Big Crown sits inside a long tube. After releasing the screw by turning it counterclockwise, the crown jumps out for the purpose of manual winding. It can also be easily pulled into the correct positions for quick-date adjustment and hand setting, and then returned securely to its screw-down, locked position.
The date mechanism is designed for quick and easy date correction. When the watch is running, it advances to the next day precisely at midnight. It makes a strong impression in black and white at 6 o’clock. The resulting omission of a luminous dot here and at 3 and 9 o’clock is no problem, since the remaining eight glowing dots and the triangle at 12 o’clock, along with the substantial hands, make it easy to read the time day or night. The chronograph function of Tudor copy with stainless steel case retreats modestly to the background during the day and disappears at night.
