If you like the look of a Black sports fake watch, the Tudor Heritage Black Bay Dark might be right up your alley. Cheaper than an all-black ceramic watch, this factory black PVD-coated steel Tudor diving watch is a modern dive series inspired by the brand’s vintage models. 
At first glance, the Tudor Heritage Black Bay Dark (ref. M79230dk-0006) looks very much like a Rolex Submariner. This is because the history of vintage Tudor Submariner is very close to that of its brother, vintage Rolex Submariner.
We have a 41mm steel case with a black physical vapor deposition (PVD) coating. The top of the case is a unidirectional rotating steel bezel, also coated with PVC, and equipped with black anodized aluminum inserts. The bezel includes a red inverted triangle, a luminous pearl at 12 o ‘clock, and a mark of 60 minutes.
Although the modern Tudor Heritage Black Bay Dark is significantly larger than 37mm Tudor Sub ref. 7924 from 1958, it borrows the ” big crown” from that vintage model. As a modern fake watch, the winding crown is closely connected to the case, forming a waterproof barrier. The crown, with its rose design – a symbol of Tudor – is a good design touch.
Also, notice the red text on the dial, this is another vintage Rolex /Tudor divers. Finally, there is a “snowflake” style pointer, also from an old Tudor diving watch from the 1970s. In addition to the glowing hands, there are a dozen glowing hour markers that provide adequate visibility in the dark.
The special Black Bay Dark comes with a grey fabric strap, Tudor also offers a PVD-coated steel bracelet and a Black leather strap to choose from. The fabric strap is secured to the wrist by a matching black PVD coated steel deployant buckle. In true Tudor style, the buckle is comfortable and durable.
In 2015, Tudor announced their first self-developed movement, MT5621, which was firstly used in the North Flag model. The MT5602 caliber is a variant of the movement made specifically for the black bay model. COSC certified automatic MT5602 movement that drives the Heritage black bay dark hands for hours, minutes, and seconds provides the wearer with a generous 70-hour power reserve. Tudor’s MT5602 beats at 28,800 BPH (4Hz) and is controlled by a variable inertial oscillator with a silicon spring that is more resistant to temperature fluctuations, shocks, and magnetism than other materials.
All in all, it is a well-made modern mechanical movement with the added prestige of being built in-house. The movement is hidden under a sturdy watch case, which is waterproof for 200 meters.
The Tudor Heritage Black Bay Dark checks off a large number of boxes with a well-proportioned case and a striking black design with white and red accents and a self-developed movement. Coupled with its relatively affordable price, this booming watch brand offers a reliable choice of modern high-quality diving replica watches.
