Tudor Black Bay Chrono "Blue Boutique" – M79360b-0002 Watch

TUDOR Black Bay Chrono "Blue Boutique" – M79360B-0002

The Black Bay Chrono Blue Boutique edition is one of TUDOR's most considered limited releases — a watch that takes the brand's in-house chronograph platform and dresses it in a palette reserved exclusively for TUDOR boutique retail. The result is a sport chronograph that is simultaneously more restrained and more distinctive than the standard catalogue offering.

Design & Dial

The deep blue sunray-brushed dial is paired with a matching blue bi-compax layout — a two-register configuration that keeps the face uncluttered and legible. The 12-hour chronograph counter sits at 6 o'clock, the running seconds at 9. Applied silver-toned hour markers and TUDOR's Snowflake hands provide the period-correct detailing that anchors the Black Bay Chrono firmly in the brand's heritage. The domed sapphire crystal adds depth to the dial, catching light in a way that shifts the blue between navy and slate depending on the angle.

The 41mm case is fitted with a blue aluminium bezel insert carrying a tachymeter scale — functional, not decorative — and the overall case geometry retains the cushion-influenced profile that distinguishes the Black Bay Chrono from more conventional round-case sport chronographs.

Case & Construction

The 41mm stainless steel case is water-resistant to 200 metres — a specification that places it well above the typical sport chronograph benchmark. The screw-down crown and pushers maintain water integrity without compromising ease of use. Case finishing combines satin-brushed flanks with polished bevels, a balance that reads as purposeful rather than decorative.

Movement

Powered by the TUDOR Manufacture Calibre MT5813 — developed in partnership with Breitling and sharing its architecture with the Breitling B01. The movement is COSC-certified, column-wheel controlled, and features a vertical clutch for cleaner chronograph engagement with minimal hand jump at start. Power reserve is approximately 70 hours. The silicon hairspring ensures antimagnetic performance and long-term rate stability without the need for frequent regulation.

Bracelet & Wearability

Presented on TUDOR's riveted three-link steel bracelet — the period-correct choice for the Black Bay Chrono — with an additional blue fabric strap included. The 41mm diameter is the largest in the Black Bay family, but the lug design and bracelet taper keep it proportionate on a range of wrist sizes. The folding clasp features a push-button release and micro-adjustment for a precise fit.

Boutique Edition Context

The "Blue Boutique" designation marks this reference as exclusive to TUDOR's own retail network — not available through authorised dealers. Production is limited, and secondary market availability is correspondingly tight. For collectors tracking TUDOR's boutique-only releases, the M79360B-0002 represents one of the more coherent executions: the blue-on-blue treatment is restrained enough to wear daily, distinctive enough to hold its own in a serious collection.

Why the Black Bay Chrono Blue Boutique?

Where the standard Black Bay Chrono is already one of the strongest value propositions in the in-house sport chronograph segment, the Blue Boutique edition adds scarcity and a more cohesive colour story without inflating the specification sheet. It is the version for collectors who have already decided on the platform and want the one that will be hardest to replicate.
