A Bold 39mm Chronograph With Yellow Dial and Manufacture Movement

Introducing the new TUDOR Black Bay Chrono 39 “Bumblebee”, a vibrant new addition to its Daring Watches collection that brings a fresh interpretation to the brand’s iconic chronograph line. Featuring a new 39mm case size, a striking yellow “Bumblebee” dial, and the in-house Manufacture Chronograph Calibre MT5813, this latest release reinforces TUDOR’s reputation for combining robustness, performance, and bold design.

Positioned alongside the “Pink” and “Flamingo Blue” editions, the Black Bay Chrono 39 “Bumblebee” expands the playful and expressive direction of the Black Bay Chrono family.

A New 39mm Case for Everyday Wear

The TUDOR Black Bay Chrono 39 “Bumblebee” introduces a more compact and refined case size, measuring 39mm in diameter and 13.1mm thick, offering improved wearability while maintaining the collection’s strong presence on the wrist.

Crafted from 316L stainless steel, the case features a combination of satin-brushed and polished finishes, highlighting the model’s sporty yet premium character. A fixed bezel in stainless steel includes a black anodised aluminium insert with tachymetric scale, reinforcing its chronograph functionality and motorsport heritage.

The redesigned proportions give the watch a more versatile fit, suitable for both daily wear and sport-oriented use.

“Bumblebee” Yellow Dial With High Contrast

The standout feature of this model is its domed yellow “Bumblebee” dial, contrasted by bold black sub-counters that enhance legibility and visual impact.

TUDOR’s signature “Snowflake” hands, a hallmark of its divers’ watches since 1969, return in a redesigned format for improved readability across the chronograph registers. All hands and markers are filled with Grade A Swiss Super-LumiNova, ensuring excellent visibility in low-light conditions.

The layout includes:

• 45-minute chronograph counter at 3 o’clock
• Small seconds at 9 o’clock
• Date window at 6 o’clock

This balanced design maintains strong visual clarity while adding a playful, high-energy aesthetic.

Manufacture Calibre MT5813

At the heart of the TUDOR Black Bay Chrono 39 “Bumblebee” is the Manufacture Calibre MT5813, a COSC-certified automatic chronograph movement developed in collaboration with Breitling and enhanced by TUDOR.

The movement features:

• Column-wheel construction
• Vertical clutch system
• Silicon balance spring
• 70-hour power reserve
• High precision certification beyond COSC standards

Operating at 28,800 vibrations per hour (4 Hz), the MT5813 ensures smooth chronograph operation and long-term reliability. The movement is visible through a sapphire crystal case back, showcasing its technical finishing and tungsten rotor.

Improved Bracelet With T-Fit Clasp

The watch is fitted with a three-link stainless steel bracelet, featuring polished and satin-brushed finishes for a refined yet sporty appearance.

It is equipped with TUDOR’s T-fit rapid adjustment clasp, allowing the wearer to adjust the bracelet length by up to 8mm without tools. The system offers five adjustment positions and uses ceramic ball bearings for smooth and secure operation.

This ensures optimal comfort throughout the day, regardless of wrist conditions.

The Black Bay Chrono 39 “Bumblebee” continues TUDOR’s long-standing connection to both motorsport chronographs and professional dive watches. By combining these two worlds, the model reinforces the Black Bay Chrono identity as a versatile sports chronograph with strong historical roots.
