Breitling Chronomat B01 42 Steel/Red Gold Green Dial UB0134131L1U1 Breitling Chronomat B01 42 Steel/Red Gold Green…

The Breitling Chronomat B01 42 is one of the most accomplished sport-luxury chronographs in modern watchmaking, and reference UB0134131L1U1 represents the model at its most visually compelling. Introduced as a reinterpretation of the original Chronomat that Breitling developed alongside the Italian aerobatic display team Frecce Tricolori in 1984, the contemporary Chronomat B01 42 retains every hallmark of that aviation heritage while housing a fully in-house manufacture movement. This is a watch built to perform and to impress in equal measure.

At 42mm in diameter, the case strikes an ideal balance between bold wrist presence and everyday wearability. The case and integrated bracelet are rendered in a steel and red gold combination—a warmer, more contemporary alternative to traditional yellow gold two-tone—giving UB0134131L1U1 a distinctly premium character. The signature rider tabs on the uni-directional ratcheted bezel serve as both a functional timing aid and a visual anchor, connecting this reference directly to the Chronomat's storied aerobatic origins.

The green dial is the detail that makes this particular reference truly special. Rich, deep green dials have become among the most sought-after executions across the entire watch industry, and Breitling's treatment here—pairing the color with index hour markers and the warm contrast of red gold applied elements—results in a dial that is simultaneously of-the-moment and destined to remain classic. Legibility is exceptional, as one would expect from a brand whose instruments have served professional pilots for decades.

Powering the watch is the Breitling Caliber B01, an entirely in-house manufacture chronograph movement that demonstrates Breitling's commitment to vertical integration. The B01 is a column-wheel, vertical-clutch chronograph, meaning the chronograph mechanism engages smoothly without the hand-jump sometimes associated with older lateral-clutch designs. This movement is COSC-certified as a chronometer, confirming accuracy standards well above the baseline for mechanical watchmaking.

The steel and red gold Rouleaux bracelet is an iconic design element of the Chronomat family, its cylindrical links providing both comfort and a distinctive aesthetic. The integrated bracelet flows seamlessly from the case, reinforcing the cohesive, purposeful design language of the entire watch. Whether worn against a suit cuff or a flight jacket, this combination projects confidence without ostentation.
