A Chronograph Designed for Every Environment

The Chronomat B01 Chronograph 42 brings together professional-grade chronograph functionality, strong visual identity, and everyday versatility. With its green dial, in-house movement, and robust construction, it represents a modern interpretation of a tool watch built not for a single purpose, but for continuous use across every setting.

Green Dial with High-Contrast Chronograph Layout

The dial is defined by a rich green tone that immediately distinguishes this model within the Chronomat collection. The colour adds depth and visual intensity while maintaining the clarity required of a professional chronograph.

Contrasting subdials provide a clear separation of chronograph functions, allowing elapsed time to be read quickly and accurately. The layout is balanced around a date display positioned at 6 o’clock, preserving symmetry while enhancing practicality for daily wear.

The dial design prioritises visibility and structure, ensuring that each element supports function as much as visual identity.

Manufacture Chronograph Movement Performance

At the core of the watch is the Breitling Manufacture Calibre 01, a self-winding mechanical chronograph movement developed for precision and long-term reliability. Built around a column-wheel architecture, it delivers smooth chronograph engagement and consistent performance under continuous use.

The movement offers an approximate 70-hour power reserve, allowing for extended operation without winding. Its construction supports stable timekeeping while maintaining the robustness required for a sports chronograph, making it suitable for both professional applications and everyday wear.

42mm Steel Case with Signature Chronomat Design

The 42mm stainless steel case defines the watch’s presence, combining strength with controlled proportions for balanced wearability. Its construction is engineered to withstand demanding conditions while maintaining a refined finish that transitions easily between settings.

The bezel features the Chronomat’s distinctive rider tabs, reinforcing both visual identity and functional grip. These elements contribute to the watch’s recognisable design language while supporting practical use.

With water resistance to 200 metres, the case is built to handle a wide range of environments, from daily use to more demanding conditions, without compromising structural integrity.

Integrated Rouleaux Bracelet with Technical Comfort

The watch is fitted with Breitling’s signature Rouleaux bracelet, a defining feature of the Chronomat collection. Its rounded link construction provides a fluid fit that adapts naturally to the wrist, delivering both comfort and stability.

The bracelet integrates seamlessly into the case, reinforcing the cohesive design of the watch while maintaining the durability expected of a professional sports model.
