Tudor has officially introduced a compact model of Black Bay Chrono by downsizing its signature stopwatch aesthetic into a much sleeker and wrist-friendly format, Black Bay Chrono 39 “Bumblebee” M79310N-0001. This latest collection features a vibrant yellow dial reminiscent of the Bumblebee robot from Transformers.
This striking timepiece belongs to an exclusive line “Daring Watches”, designed for enthusiasts who appreciate highly expressive color choices. The bold visual concept pays direct homage to the iconic racing spirit and historic sports chronographs of yesteryear.
Specifically, the vibrant color scheme draws creative energy from the colorful classic racing chronographs of the nineties. This aesthetic creates an energetic, high-contrast look that quickly earned the playful nickname among watch enthusiasts worldwide.
It represents a proud extension of historical identity mixed with a completely modern, forward-thinking approach to design. The watch serves as an artistic statement, proving functional tools can also be incredibly vibrant and fashion-forward.
Specification
The biggest news about this reference centers entirely on the major changes made to the steel case. The outer case has been downsized to 39mm, a sweet spot that offers widespread appeal and excellent wrist presence. This choice marks a substantial decrease from the 41mm diameter found on older family members.
Furthermore, engineering advancements allowed the brand to reduce the overall case thickness down to just 13.1mm. The resulting profile sits noticeably lower on the arm, eliminating the top-heavy feel of previous editions.
A compact lug-to-lug length of 47mm ensures the watch hugs smaller and average wrists beautifully. The case combines satin-brushed surfaces on top with highly polished bevels running along the elegant sides.
Securing this high-end sports timepiece to the wrist is a beautifully engineered 3-link stainless steel bracelet with brushed finish on top and polished flanks that mirror the casework. The bracelet is completed by TUDOR “T-fit” rapid adjustment clasp.
This micro-adjust mechanism allows the wearer to easily extend or shorten the band length by 8mm. This practical addition provides instant comfort changes as your wrist size fluctuates throughout hot or cold days.
Fans will be happy to notice the complete absence of the older faux-rivet design details here. The bracelet sides are completely smooth, creating a contemporary and clean look from every viewing angle.
This latest model also features a fixed steel bezel with a black anodized aluminum insert featuring a tachymeter scale, white numerals, and a strip for clear legibility. The collection features a domed sapphire crystal to protect the dial. A screw-down crown is located at 3 o’clock, while screw-lock pushers are placed at 2 and 4 o’clock.
Dial
The most captivating feature of this watch is undoubtedly its beautiful and eye-catching domed face layout. The background is covered in a rich, matte yellow color that eliminates harsh reflections in bright sunlight.
This smooth, non-shiny texture allows the dark details to stand out with incredible clarity and contrast. Two deeply recessed black sub-counters sit across the face, at 3 and 9 o’clock, forming a classic and highly balanced design.
These sub-dials provide a distinct contrast against the yellow background. The hands and applied hour markers are fully blackened to maximize readability during daily activities.
The iconic Snowflake hands receive a slight modification to ensure they never block the underlying timing dials. White Super-LumiNova fills these hands and round markers, ensuring excellent visibility during dark nighttime conditions.
Movement
This watch is powered by automatic chronograph movement caliber MT5813 (base Breitling B01) with column-wheel system and COSC-certified. The movement operates on 28,800 vph, providing an impressive 70 hours power reserve, accuracy -2/+4 seconds per day.
A non-magnetic silicon balance spring helps protect the movement from the disrupting effects of modern magnetic fields. The mechanism ensures daily accuracy stays well within stringent chronometer standards for reliable everyday timekeeping performance.
The Tudor Black Bay Chrono 39 “Bumblebee” M79310N-0001 is a regular production model rather than a limited edition. However, as part of the exclusive “Daring Watches” series, availability remains relatively limited at global retail points. The retail price for this downsized, yellow-dial sports chronograph is set at EUR 6,200.
