Tudor Black Bay Chrono 39 Ref. 79310N “Bumblebee Yellow”

The Tudor Black Bay Chrono 39, reference 79310N, from 2026—aptly dubbed “Bumblebee” among collectors—marks a milestone in the Swiss manufacture’s modern sports watch collection. As a long-awaited, more compactly proportioned evolution of the previous 41 mm chronographs, this model combines vintage-inspired motorsport character with a radically fresh color aesthetic. The bright Yellow dial, contrasting with the deep black totalizers and matching bezel, gives the robust stainless steel case an unmistakable, dynamic presence on the wrist.

• Ergonomically optimized 39 mm steel case: Crafted from satin-brushed and polished stainless steel. With its reduced 39 mm diameter, slimmer height of just 13.1 mm, and shorter 47 mm lug-to-lug distance, this model offers significantly improved wearing comfort compared with its predecessors.

• Fixed bezel with black anodized Aluminium insert: The polished stainless steel bezel features a tachymeter scale on a matte black background with silver indices, evoking the classic look of historic racing chronographs.

• Bright Yellow “Bumblebee” dial with Panda totalizers: The striking domed dial in vivid Yellow is perfectly complemented by two contrasting, recessed black subdials (Bi-Compax layout with small seconds and a 45-minute counter).

• Practical date window at 6 o’clock: Harmoniously integrated into the lower half of the dial, the discreetly positioned date display ensures absolute symmetry in the dial design.

• In-house manufacture Calibre MT5813 (COSC-certified): Inside, the high-precision automatic chronograph movement with column wheel and vertical clutch (based on Breitling Calibre B01) beats. It features an antimagnetic silicon balance spring and delivers accuracy of -2 to +4 seconds per day, with a power reserve of approximately 70 hours.

• Domed Sapphire Crystal: A heavily domed Sapphire Crystal protects the striking dial and underscores the classic domed case aesthetic of the Black Bay line.

• Screw-down crown and pushers: The stainless steel screw-down winding crown, embossed with the Tudor shield in relief, along with the screw-down chronograph pushers, ensures maximum security.

• Outstanding water resistance (200m / 660 ft): Thanks to its hermetically sealed screw-down case back, the chronograph offers exceptional diving capability for a sports watch of this kind.

• Three-link stainless steel bracelet with “T-fit” clasp: The reference is worn on a satin-brushed and polished three-link Oyster steel bracelet, featuring Tudor’s innovative, tool-free “T-fit” rapid adjustment for a precise fit.

• Striking performance statement (2026 edition): The reference 79310N in the “Bumblebee” version boldly breaks with convention, combining uncompromising Swiss manufacture technology with a daring, polarizing design statement.
