A Defined and Technical Chronomat

The Chronomat B01 Chronograph 42 (AB0158101A1A1) delivers a sharper and more structured interpretation of the collection through its high-contrast dial and proven manufacture movement. With its combination of chronograph capability, durable construction, and distinctive design, it stands as a modern execution of a professional sports watch built for continuous use.

White Dial with Reverse Panda Chronograph Layout

The dial is executed in white with contrasting black subdials, creating a classic reverse panda configuration that enhances legibility and visual structure. This high-contrast layout separates chronograph functions clearly, allowing elapsed time to be read with precision.

Applied indexes and luminous elements maintain clarity in varying light conditions, while the date display at 6 o’clock preserves symmetry across the dial. The overall composition balances technical readability with a strong, recognisable aesthetic.

Manufacture Chronograph Movement Performance

At the centre of the watch is the Breitling Manufacture Calibre 01, a self-winding mechanical chronograph movement engineered for precision and durability. Built with a column wheel and vertical clutch system, it delivers smooth chronograph engagement and consistent timekeeping under regular use.

The movement provides an approximate 70-hour power reserve, allowing for extended operation without winding. Designed for reliability, it supports both technical performance and practical daily use within a robust sports chronograph framework.

42mm Steel Case with Signature Rider-Tab Bezel

The stainless steel case measures 42mm, delivering a strong presence while maintaining comfort through refined proportions. Its construction is engineered for durability, with water resistance rated to 200 metres for use across a range of conditions.

The bezel features the Chronomat’s distinctive rider tabs positioned at the quarter-hour markers, a defining characteristic of the design that enhances grip and recognisability. This element reinforces both functionality and the collection’s long-standing identity.

Rouleaux Bracelet with Integrated Construction

The watch is fitted with the Rouleaux bracelet, an integral component of the Chronomat design. Its rounded links provide a flexible and stable fit, ensuring comfort across extended wear.

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