Stainless Steel TUDOR HERITAGE BLACK BAY DARK Swiss Made Watch

This Stainless-Steel TUDOR Heritage BLACK BAY Dark Swiss-made wristwatch sports a customary 41mm stainless steel case. To achieve its all-black look, the ref. 79230DK is treated with a black Physical Vapor Deposition (PVD) coating with a satin finish. On top of the case sits a unidirectional rotating bezel (also made from PVD-coated steel), and fitted with a black anodized aluminum insert. The bezel includes a red inverted triangle with a luminous pearl at 12 o'clock and a 60-minute timing scale for divers to keep tabs on how long they've spent underwater. 

The first 15 minutes of the insert’s scale includes marks at every minute followed by a marking every 5 minutes for the rest of the insert. The winding crown screws down onto the middle case to create a waterproof barrier. A closer look at the crown reveals an engraved rose emblem, which is the brand’s earliest logo. The only use of colour on the Black Bay Dark is the red text for the depth rating (200m, 660ft) on the dial and an inverted red triangle on the bezel. These touches add a throwback to vintage Tudor (and Rolex) dive watches. One of the signature design details of all Tudor Black Bay watches is the angular snowflake hands, allowing the white lume of the hands and hour markers to pop against the black elements while the lack of a date window allows the dial layout to remain uncluttered and appealingly symmetrical. It embodies a domed sapphire crystal. 

The watch is attached to a sporty black leather strap with buckle and comes with an aged black leather strap fitted with a black PVD-treated steel folding clasp, for an optional look. Plus, the Tudor Heritage Black Bay Dark comes with an additional Jacquard fabric strap. Earlier models of the Heritage Black Bay ran on ETA-based movements but in 2015, Tudor announced its first in-house movement, the Caliber MT5621, which made its debut in the North Flag models. Since the Black Bay Dark was released the year after, it benefited from the addition of a Tudor-made movement: the Caliber MT5602. The automatic MT5602 movement that drives the hour, minute, and seconds hands has a 70-hour power reserve. The watch beats at a frequency of 28,800 beats per hour (4Hz), and it is regulated by a variable inertia oscillator fitted with a silicon hairspring (which fares better against temperature swings, shocks, and magnetism than other materials). 

The movement is COSC-certified and as a result, Tudor includes the “Chronometer Officially Certified” designation on the dial of the Black Bay Dark. All in all, the Tudor Caliber MT5602 is a well-made modern mechanical movement that has the added cachet of being made in-house by Rolex’s famous sibling company. The Black Bay Dark has recently disappeared from Tudor’s current collection. Therefore, the pre-owned market is now the go-to source to find this sleek Tudor dive watch, and due to only remaining in production for about 5 years, there are not all that many examples available compared to its standard stainless steel siblings. The watch was produced from 2016 - 2021 and given that this all-black model is no longer available at a retail level and there is now a fixed number of examples in existence, prices should be expected to increase in the future. The model is #79230DK and serial # is I602244. The watch comes with the original box and papers, as well as the aforementioned watch straps. The original purchase date was 07/13/2019.

Tudor watches, founded by Hans Wilsdorf, the same man behind Rolex, was initially known for producing watches for the military and professional divers. It is a sister company to Rolex offering high-quality watches at a more affordable price point. Tudor combines Swiss craftsmanship with accessible pricing, providing a range of watches from professional diving instruments to elegant dress watches. Tudor's purpose was to offer a more affordable watch than Rolex while maintaining Rolex-like quality.
