“Some watches become interesting because they marked a break with the past. Others because they managed to bring a memory back without turning it into imitation. The Black Bay belongs to this second family: a modern watch carrying, in its dial, its hands and the colour of its bezel, something of Tudor’s historic diving watches without ever pretending to be an old watch.”

The 2015 Tudor Heritage Black Bay 79220B occupies a very particular place in Tudor’s recent history. It belongs to the first generation of Black Bay watches, the generation that re-established the brand’s heritage identity in the early 2010s and laid the foundations for a collection that would become one of Tudor’s major pillars. The 79220B, immediately recognisable by its blue bezel, is particularly sought after because it still belongs to the period when Black Bay watches were powered by ETA movements, before Tudor introduced its manufacture calibres. It therefore combines an aesthetic that has already become emblematic with a simple, robust and thoroughly proven movement, giving it an identity quite different from later generations.

Introduced after the first red-bezel Black Bay, the blue version has a colder, more nautical and arguably more versatile personality. The blue bezel contrasts with the black dial without becoming overly demonstrative. It naturally evokes the sea and also recalls certain historic blue Tudor divers, particularly those associated with the French Navy. This modern Black Bay should not be confused with a military-issued watch, but its visual language clearly belongs to the diving heritage that Tudor has used with remarkable intelligence.

The 41 mm stainless-steel case gives the watch strong but balanced presence. Its proportions are those of a modern diver, with a solid case, substantial screw-down crown and easily operated bezel. The domed sapphire crystal creates a slightly vintage impression while retaining the resistance expected from a contemporary watch. This is one of the great successes of the Black Bay: it adopts the proportions and details of older diving watches while translating them into a watch designed to be genuinely worn today.

The black dial is immediately legible. Large luminous hour markers, a simple minute track and especially the Snowflake hands give the watch an instantly recognisable Tudor identity. This hand design first appeared historically on Tudor divers in the late 1960s to improve legibility. On the Black Bay it once again becomes a strong, almost graphic signature, clearly separating Tudor from the Rolex universe while recalling the shared history of the two houses. The blue unidirectional bezel strengthens this identity. As on any genuine diver, it allows elapsed time to be followed by aligning the bezel marker with the minute hand. Unidirectional rotation follows a classic safety principle: accidental movement can only indicate a longer elapsed time than reality. Outside the water, the bezel also becomes a useful tool for timing a journey, exercise session or cooking period, reminding us that a diving watch remains first and foremost a tool watch.

The original 200-metre water resistance confirms this vocation. Screw-down crown, screw-down caseback and overall case architecture allow the Black Bay to be used in an aquatic environment, provided of course that a recent water-resistance test confirms the actual condition of the individual watch before immersion. The presence of a recent service invoice adds further interest here because it documents recent maintenance and provides additional transparency regarding the watch’s technical history. Inside is the ETA 2824-2, a well-known Swiss automatic movement celebrated for robustness and serviceability. It operates at 28,800 vibrations per hour, contains 25 jewels and provides approximately 38 to 42 hours of power reserve after full winding. In this first generation of Black Bay, the movement contributes greatly to the charm of the reference. Later versions moved to Tudor’s manufacture calibre, offering more modern performance and greater autonomy, but the 79220B retains the mechanical simplicity many collectors appreciate: a proven movement familiar to watchmakers and entirely coherent with the spirit of a robust watch designed to be worn.

It is precisely this distinction between ETA Black Bay and manufacture Black Bay that gives the 79220B a special place in the range today. The first generation now appears as a turning point: Tudor was rediscovering its historical identity, returning to the aesthetic of its old diving watches and unknowingly preparing one of the great watchmaking successes of the decade. The 79220B therefore belongs to the birth of the Black Bay phenomenon, and that gives it an interest beyond that of an ordinary modern diver.

The blue NATO strap perfectly suits this philosophy. It reinforces the nautical and military-inspired character of the watch without becoming a caricature. It also makes the watch feel considerably lighter on the wrist and visually reduces the presence of the 41 mm case compared with a steel bracelet. On a watch designed for the sea, NATO remains a coherent practical solution: simple, durable and easy to replace.

The Full Set of this example is particularly appealing. The watch is accompanied by its original box, original papers, original purchase invoice and a recent service invoice. For a collector, this documentation provides genuine continuity in the history of the watch. The original invoice places the piece clearly within its initial commercial context, while the recent service invoice documents its mechanical follow-up. On a first-generation Black Bay, this degree of documentation is becoming increasingly appreciated.

A 2015 79220B can be worn in many different ways today. It works as a diving watch, travel watch, weekend watch or simply as an everyday watch. Its black dial and blue bezel provide substantial versatility, while the NATO strap adds a more relaxed character. It can accompany city clothes, denim, a polo shirt or nautical equipment without feeling out of place. This ease of use explains much of the Black Bay’s success: it has enough history to interest a collector, yet remains simple enough to be worn without excessive concern.

For a Tudor collector, this reference is especially interesting because it comes from a period when the brand had rediscovered a genuine identity of its own while still retaining some technical elements from an earlier generation. The 79220B ETA is therefore now a transitional model, combining modern styling with more traditional mechanics. That mixture is probably what makes it so appealing: neither entirely old nor entirely contemporary, it captures much of what made Tudor successful at the beginning of the 2010s.

The Tudor Heritage Black Bay 79220B ultimately represents one of the most interesting periods in Tudor’s modern history. It tells the story of the moment when the brand rediscovered its tool-watch roots while creating a new, contemporary and immediately recognisable aesthetic. Its blue bezel, Snowflake hands, ETA movement and complete 2015 set make it an especially appealing piece today, historical enough for the collector and robust enough to continue being worn. A modern Tudor that has already become an important transitional reference, and a watch that perfectly captures the brand’s resurgence at the beginning of the 2010s.
