Tudor Black Bay 79500

The 79500’s chronology is best understood as a series of independent additions rather than a sequence of formal marks. Tudor launched the 36 mm watch in 2016 with a black semi-gloss dial, applied round markers, batons at three, six, and nine, an inverted triangle at twelve, and the snowflake hour hand. The fixed polished bezel established that this was a Black Bay in family language but not a smaller version of the rotating-bezel diver.

Blue was added in 2018 as an additional configuration. The reason for the color expansion is not documented, but the case, hand set, dial architecture, and ETA-based movement remained the same. Silver arrived approximately in 2021, generally described as a silver or sunburst execution, again without changing the basic case or time-only layout. These color windows should not be used as movement dates.

The movement and dial-text story is separate. Early examples use Tudor’s ETA 2824-2-based execution and are recognized by the curved “Rotor Self-Winding” wording above six o’clock. Later straight-text watches are associated with the replacement generation and a Tudor/Sellita-based movement description, but the precise changeover is not established by a reliable serial cutoff. That is why a straight-text watch deserves a reference and movement check rather than a confident date assignment.

The original production boundary is similarly approximate. Public evidence supports a run around 2016–2022, while the redesigned M79640 was phased into the collection around 2023. The successor changed more than the movement, adding crown guards, a redesigned case and bracelet architecture, COSC certification, and approximately 70 hours of reserve through the MT5400 family. In a few years, the Black Bay moved from a single compact configuration to a small set of independently datable choices, then into a new manufacture-movement generation.

The closest comparisons show what the 79500 changed and what it later gave up. The 79220 family supplies the direct visual ancestor, a larger rotating-bezel diver, while the M79640 is the true successor, not a late 79500 suffix. The two-tone M79503 is a useful sibling only because it demonstrates how far the redesigned 36 mm concept moved beyond the stainless-steel original.

Buying a 79500 is less about finding a rare mark than about separating a correct configuration from a loosely dated listing. The reference has several factory dial colors and bracelet or strap arrangements, but no authoritative serial cutoff for the later dial-text and movement discussion. A buyer should therefore treat “early,” “transitional,” and “rare” as claims to verify, not as automatic premiums.

The safest purchase is one where the reference, dial, handset, movement, case finishing, and accessories agree. The 19 mm lugs can complicate replacement straps, while the 150 metre rating makes seal and crown condition more than cosmetic concerns. Original bracelet, complete links, sharp case geometry, documented service, and coherent paperwork generally matter more than dial color alone. For someone who wants a compact Tudor with the Black Bay’s snowflake hand but without a rotating bezel, the 79500 offers a direct, wearable expression of that idea. It feels purpose-built for daily use, provided the watch has not been polished soft, fitted with incorrect parts, or sold with an unsupported story about its date.
