  • Winding crown

    The winding crown is used to set the time and to wind the watch if it has not been worn. The winding crown is screwed down onto the case to ensure water resistance. It must be fully tightened after each manipulation.

  • Seconds hand

    The hand indicating seconds.

  • Hour and minute hands

    The hands on the watch that indicate the time.

  • Bezel

    The unidirectional rotatable bezel allows precise measurement of dive times. For safety, the bezel rotates in one direction only. It is deliberately harder to turn when the zero marker (triangle) is in the 12 o'clock position to avoid inadvertent rotation.

EMBLEMATIC LOOK

The Black Bay remains one of TUDOR’s most recognized and recognizable lines. In its latest 43mm iteration, the new case keeps the proportions of the original design while now being slightly thinner. The unidirectional rotatable bezel offers very prehensible sides and its insert shows subtly curved numerals aligning with the outline of the outer ring. However, the aesthetic details don’t stop at case dimensions and bezel. The seconds hand recalls the look of the early diving watches of the brand with a lollipop design, while the silver or TUDOR Blue dial is softly radial-brushed for a very subtle shine under direct light. Ergonomics have evolved as well, with a redesigned crown, reminiscent of the curves found on the crowns of the brand's historical technical watches, that is set flush to the middle case band so that its tube is not visible.

  • The build of the Manufacture Calibre MT5601-U is designed to ensure robustness and precision. To do this, the variable inertia balance wheel is maintained by a sturdy traversing bridge with two-point anchoring. It is certified as a chronometer by the Official Swiss Chronometer Testing Institute (COSC), with its performance going beyond the standards set by this independent institute. Not only is the Manufacture Calibre MT5601-U certified to be more accurate, it is also rated as anti-magnetic, making it impervious to magnetic fields below 15,000 gauss.

  • The Black Bay comes fitted on an entirely satin-brushed 3-link stainless steel bracelet that features smooth flanks on the links, departing from the "rivet-style" bracelet typical of the Black Bay range. Additionally, the taper is gradual, contrasting the "ladder-style" taper that is also typical of the Black Bay. The redesigned bracelet was developed with wearing comfort in mind to match the aesthetics of the largest Black Bay in the line-up. It also features the TUDOR "T-fit" rapid adjustment clasp. Easy to use, requiring no tools and offering five positions, this practical system allows wearers to carry out a fine, instant adjustment of the total length of the bracelet along an adjustment window of 8mm. The clasp also features ceramic ball bearings that ensure a smooth and secure closure in addition to adding a pleasing tactile element to the action of the clasp.
