Black Bay Chrono 41mm Black Dial / Silver Counters / 5-link Steel Bracelet
The Tudor Black Bay Chrono M79360N-0013 is a 41mm steel chronograph with a black with silver counters, domed, 200m water resistance, fixed tachymeter bezel and Tudor's COSC-certified MT5813 chronograph movement. Its strongest argument is the movement package: column-wheel and vertical-clutch architecture at a price below many prestige chronographs.

Executive Verdict
The Black Bay Chrono is technically strong, but the page must be variant-aware. M79360N alone is not enough to describe one exact watch. For M79360N-0013, the correct package is a 41mm steel case, 14.4mm thickness, black dial with silver counters, 200m water resistance, domed sapphire crystal, fixed aluminium tachymeter bezel and MT5813 chronograph calibre. The watch is strong value for a Swiss mechanical chronograph, especially because of the MT5813 movement, but it is thick, visually busy and not as cleanly focused as a pure dive watch or pure racing chronograph.
Buyers who want a COSC column-wheel chronograph with strong MT5813 substance and can wear a 41mm / 14.4mm case comfortably.
Buyers who need a slim, pure racing chronograph identity, or who dislike mixed dive/chrono design language.

Movement Truth
Tudor Manufacture Chronograph Calibre MT5813
Buyer meaning: One of the strongest reasons to buy a Tudor Black Bay Chrono: modern column-wheel chronograph, 70h reserve and COSC at below many prestige chronograph prices, with the caveat of chronograph service complexity.
The Black Bay Chrono uses Tudor's Manufacture Chronograph Calibre MT5813, a COSC-certified self-winding chronograph movement with approximately 70 hours of power reserve. Tudor describes it as a Manufacture Calibre, while independent technical coverage explains its Breitling B01 connection and Tudor-specific modifications. The right way to frame it is not as a basic outsourced chronograph, but also not as a fully isolated Tudor-only in-house movement. It is a high-spec collaboration movement with column wheel and vertical clutch architecture, and it is one of the strongest technical arguments for the watch.
MovementIntel breakdown
B01-derived automatic chronograph with column wheel and vertical clutch; integrated high-spec architecture.
High confidenceCOSC chronometer positioning with modern regulation hardware.
High confidenceRoughly 70 hours is excellent for an automatic chronograph.
High confidenceModern Tudor/Breitling collaboration architecture with silicon balance spring in source-backed coverage.
Medium confidenceMore complex than simple ETA/Sellita/Valjoux three-hand movements; best through Tudor authorized or qualified chronograph specialists.
Medium confidenceNot Tudor-only, but a real collaboration calibre with distinct technical identity versus generic 7750-family chronographs.
Medium confidenceAttractive industrial Tudor finishing with laser decoration; not haute horlogerie hand-finishing.
High confidenceVery strong inside Tudor Black Bay Chrono compared with many luxury chronographs.
Medium confidencePublic label: Manufacture collaboration calibre
A brand manufacture calibre built on a documented collaboration or shared architecture with another manufacture, such as Tudor MT5813 on Breitling B01. Not generic outsourced, but not fully isolated either.
Source nuance: Tudor officially calls MT5813 a Manufacture Chronograph Calibre. Independent sources identify it as based on Breitling B01 architecture and created through a Tudor-Breitling collaboration. It is not an off-the-shelf ETA/Sellita/Valjoux movement, but it should not be described as a fully isolated Tudor-only in-house calibre.
WatchIntel never overclaims "in-house" without source nuance. Manufacturer marketing language may differ.
Value for Money
Strong for a mechanical Swiss chronograph, but not automatic buy for every wrist. The MT5813 movement gives the watch serious technical substance, but the 41mm case and 14.4mm thickness mean fit matters. Value is strongest when bought at official retail or sensible pre-owned pricing, not when treated like a scarce Rolex substitute.
Hype Tax
Moderate. Tudor benefits from Rolex-group halo and Black Bay popularity, but this watch also has real technical substance. The hype is not empty, but the buyer still pays for brand positioning and Black Bay demand.
Serviceability
Best handled through Tudor authorized service. A column-wheel chronograph is more complex than a simple three-hand movement, and servicing should not be described as cheap or simple.
Resale & Liquidity
Good for Tudor, but variant-sensitive. Panda, reverse panda, bracelet type, condition and full-set status matter.
