Tudor’s more playful side is becoming hard to ignore.
After the candy pink Black Bay Chrono in 2024 and the soft turquoise Flamingo Blue edition in 2025, the brand’s colour-led chronograph story now gets a sharper, more graphic chapter with the Black Bay Chrono 39 “Bumblebee”.
The formula is simple but effective, with a bright yellow dial, black sub-dials and a 39mm steel case that keeps the whole thing wearable rather than theatrical.
At a glance
- Tudor introduces the Black Bay Chrono 39 “Bumblebee” as the third vivid entry in its Daring Watches series.
- The watch pairs a bright yellow dial with black azuré-finished sub-dials, a black bezel insert and signature snowflake hands.
- It uses Tudor’s in-house MT5813 automatic chronograph calibre, COSC-certified and rated for a 70-hour power reserve.
A brighter turn for the Black Bay Chrono
The Black Bay Chrono has always carried a certain visual tension, sitting between Tudor’s dive-watch language and the more technical requirements of a sports chronograph.
With the Bumblebee, that tension becomes the point.
The yellow-and-black palette is far more direct than the pastel mood of the Pink and Flamingo Blue models, giving the watch a higher-contrast, almost instrument-like presence.
It’s not a quiet dial, but Tudor has kept the design grounded through a familiar Black Bay silhouette and a restrained two-register layout.
The 39mm diameter is especially important here, as it prevents the colour from overwhelming the wrist.
At 13.1mm thick, the steel case still has the substance expected from an automatic chronograph, but the proportions should make it approachable for a broad range of wrists.
Yellow dial, black registers and snowflake hands
The centre of the watch is all about contrast.
A saturated yellow dial sets the tone, while the black sub-dials at 3 and 9 o’clock pull the layout back into classic chronograph territory.
The register at 3 o’clock handles the 45-minute chronograph counter, while the small seconds sits opposite at 9 o’clock.
That symmetry gives the dial an easy read, even with a colour this bold.
Tudor’s signature snowflake hands remain in place for the hours and minutes, a design cue tied to the brand’s dive watches since 1969.
Here, they sit above applied geometric hour markers that have been blackened and filled with luminescent material.
A date window at 6 o’clock displays black numerals on a white disc, adding a practical note without breaking the dial’s main two-colour rhythm too aggressively.
The fixed bezel continues the dark framing effect, using a black anodized aluminium insert with silver numerals.
It gives the watch a crisp outer edge and reinforces the motorsport-adjacent personality that has long made chronographs so adaptable in daily wear.
MT5813 chronograph calibre inside
Behind the vivid exterior is Tudor’s in-house MT5813 automatic chronograph movement.
The calibre is COSC-certified as a chronometer, which places accuracy at the centre of the watch rather than leaving the dial colour to do all the work.
Its 70-hour power reserve is one of the more useful details for real ownership.
Leave the watch off the wrist for a weekend and it should still be running when Monday arrives, assuming it was fully wound beforehand.
That combination of strong mechanics and extroverted colour is what makes the Bumblebee more than a novelty dial.
It’s a serious Black Bay Chrono wearing a less serious suit, and that balance is exactly where Tudor has found momentum with this recent run of expressive models.
