Breitling Chronomat B01 Chronograph 42 (UB0134131L1U1)

Breitling Chronomat B01 42 Chronograph UB0134131L1U1 It is one of the standout models in the contemporary Chronomat collection, blending a sporty spirit with refined elegance and the highest standards of Swiss watchmaking. The Chronomat line holds a unique place in the manufacture’s history, as it symbolically reintroduced mechanical chronographs to the brand’s lineup in 1984, a time dominated by quartz watches. Its creation was inspired by a model developed in collaboration with the Italian aerobatic team Frecce Tricolori—a heritage reflected to this day in the collection’s bold styling and functional character. Reference UB0134131L1U1 offers a luxurious interpretation of this legend, harmoniously combining stainless steel and 18k rose gold with a striking green dial that gives the watch a distinctive personality.

The 42-millimeter case is crafted from stainless steel and accented with 18-karat rose gold elements, adorning the rotating bezel—complete with its signature rider tabs—and select bracelet links. This combination of materials ensures the model retains its sporty durability while exuding an air of exceptional prestige. The surfaces feature a meticulous finish alternating between brushed and polished textures, allowing light to subtly accentuate every structural detail. A screw-down crown and substantial chronograph pushers ensure high functionality, while a water-resistance rating of 200 meters makes the watch suitable for both daily wear and water-based activities. Despite its robust construction, the Chronomat remains perfectly balanced, offering great wearing comfort even over extended periods.

The most eye-catching feature of this reference is the green dial, boasting a deep, saturated hue that shifts from dark forest green to subtle emerald highlights depending on the angle of the light. Contrasting black chronograph sub-dials lend the composition a dynamic character and perfectly underscore the model’s sporty roots. The applied hour markers and hands are coated with Super-LumiNova, ensuring excellent legibility both by day and after dark. The date display at the six o’clock position integrates harmoniously into the dial layout, preserving its symmetry and elegance. The overall design remains exceptionally legible despite the wealth of information displayed—a hallmark strength of the Chronomat collection for years.

A signature feature of the model remains the iconic Rouleaux bracelet, whose rounded links have become one of the brand’s most recognizable symbols. In this version, it is crafted from stainless steel with 18k rose gold central links, creating a cohesive look with the case. The bracelet’s design ensures exceptional wearing comfort and conforms perfectly to the wrist. Its distinctive appearance pays homage to models from the 1980s while remaining an incredibly modern and elegant choice. It is precisely the Rouleaux bracelet that makes the Chronomat recognizable from a distance and sets it apart from other luxury chronographs on the market.

At the heart of the model lies the Breitling Manufacture Caliber 01—an in-house automatic movement and one of the most highly regarded contemporary chronograph calibers. Operating at a frequency of 28,800 vibrations per hour, the movement features a column-wheel mechanism and a vertical clutch, ensuring exceptionally smooth and precise chronograph operation. The caliber offers a power reserve of approximately 70 hours and holds COSC chronometer certification, attesting to its high precision. A transparent case back allows one to admire the meticulously finished movement, complete with its distinctive rotor and decorative details that reflect a high level of in-house craftsmanship. It is a construction valued by both wearers and professional watchmakers alike for its reliability, durability, and ease of servicing.

The Chronomat B01 Chronograph 42 perfectly demonstrates that a sports chronograph can also be exceptionally elegant.
