TUDOR Black Bay Chrono 39 Bumblebee

Causing a Buzz with the New TUDOR Black Bay Chrono “Bumblebee”

TUDOR’s Black Bay Chronograph line, first launched in 2017 with the reference 79350 of the same name, has seen myriad variations of dial, strap, and design over the years since. The Maison’s latest release, however, marks an exciting first for the collection, as the new TUDOR Black Bay Chrono “Bumblebee” becomes the first of its name to feature a slimmer 39mm diameter. 

As visually striking as it is versatile and practical, the latest iteration of the TUDOR Black Bay Chrono represents an exciting step forward for the collection, expanding its offering to a much wider range of wrists and sensibilities. It joins its “Pink” and “Flamingo Blue” cousins as another colourful addition to TUDOR’s Daring Watches lineup, injecting this classically sporty timepiece design with a sense of contemporary character and personality. Bright, compact, and astonishingly yellow, this handsome new model is sure to cause a buzz wherever it goes. 

Small But Mighty: A Slim Yet Striking Watch Face 


The star feature of this new TUDOR Black Bay Chrono release is indubitably the domed, bright yellow “Bumblebee” dial, its vibrant hue offset by two contrasting circular black sub-counters – hence the nickname. In fact, the entire face is a veritable sea of juxtaposition, with vivid yellow paired against white and black accents throughout – the result is one of expressive refinement, visually arresting without appearing overwrought or busy. Faithful to the Black Bay aesthetic, the model boasts two of TUDOR’s ubiquitous “Snowflake” hands, a brand signature for their divers’ watches since 1969, here further honed to ensure optimum readability against the watch’s bright yellow dial. 

TUDOR has completely reimagined the classic Black Bay Chrono case for this slimmer 39mm diameter, measuring 2mm narrower and 1.3 mm thinner than its 41mm-wide predecessors for a sleeker and more refined wearing experience. Crafted from 216L stainless steel and presented with a combination of satin-brushed and polished finishes, this compact new addition to the TUDOR Black Bay Chrono line feels suitably sporty without dominating the wrist entirely, offering presence and poise in equal measure. 

Although it has been sized down in proportion with the rest of the watch, the TUDOR Black Bay Chrono "Bumblebee"’s case still retains much of its collection’s iconic design codes, such as the large crown sat between two chronograph pushers. In all, it represents a bold statement of intent for the future of the TUDOR Black Bay Chrono collection, reengineering these esteemed models to suit a wider range of wrist profiles and preferences. 

New Look, Same Manufacture Movement


The significantly slimmer proportions of the new TUDOR Black Bay Chrono “Bumblebee” belie the Manufacture Chronograph Calibre MT5813 that faithfully powers it. As of now it remains the movement of choice for the entire TUDOR Black Bay Chrono collection, and so boasts impressive functionality: individual hour, minute, second, chronograph, and date functions, as well as a healthy 70-hour power reserve and a silicon balance spring, which helps to protect the watch against dramatic temperature changes and magnetic interference. 

Its movement is COSC-certified to an accuracy within -2/+4 seconds a day, and the diving heritage of the TUDOR Black Bay Chrono is honoured by a water resistance rating of up to 200m, making this an excellent all-weather companion for daring and adventurous wrists. 

A Stylish Steel Bracelet


The TUDOR Black Bay Chrono "Bumblebee" arrives on a new three-link stainless-steel bracelet with smooth link sides and TUDOR’s T-fit rapid adjustment clasp, allowing for quick, on-the-fly changes within a generous 8mm window. It also features ceramic ball bearings, which ensure a smooth and secure closure while adding a pleasing tactile element to the action. The refreshed proportions of the tapering three-link bracelet allow for comfortable ergonomics whilst the integrated end-links add a sense of refinement and elegance, affording the watch a more ‘mature’ character than its predecessors.

As with every TUDOR timepiece, the watch is covered by a five-year transferable guarantee, with no registration or mandatory maintenance checks required.
