A Refined Chronomat for Everyday Wear

The Chronomat B31 Automatic 40 (AB3114101C1A1) reflects a modern direction for the collection, prioritising clarity, comfort, and long-duration performance. With its streamlined dial, extended power reserve, and balanced proportions, it offers a practical and technically advanced interpretation of the Chronomat built for everyday use.

Blue Dial with Clear and Balanced Layout

The dial is finished in a strong blue tone that adds depth while maintaining clarity across the display. Without chronograph subdials, the surface remains open and highly legible, allowing time to be read instantly.

The design is anchored by a date display that integrates cleanly into the dial, preserving symmetry and ensuring practical functionality. This simplified layout reinforces the watch’s role as a daily timepiece built for clarity rather than complexity.

Next-Generation Manufacture Movement Performance

At the centre of the watch is the Breitling Manufacture Calibre B31, a self-winding mechanical movement designed to deliver extended performance and long-term reliability. The movement offers an approximate 78-hour power reserve, allowing it to run for several days without interruption.

Its construction is engineered for stability, maintaining consistent timekeeping while supporting a slimmer overall case profile. Designed for continuous use, it reinforces the Chronomat’s position as a modern everyday sports watch.

40mm Steel Case with Refined Proportions

The 40mm stainless steel case is designed for versatility, offering a balanced size that suits a wide range of wrist profiles. The proportions ensure comfort while maintaining the structural strength required of a high-performance sports watch.

With a thickness just under 11mm, the case remains relatively slim, allowing it to sit easily under a cuff while still delivering presence on the wrist. The construction provides water resistance to 200 metres, supporting durability in a variety of environments.

Rouleaux Bracelet and Integrated Design Identity

The watch is fitted with the signature Rouleaux bracelet, a defining element of the Chronomat collection. Its rounded link construction provides flexibility and comfort while maintaining a distinct visual identity.

Designed for daily wear, the bracelet integrates seamlessly with the case and includes an adjustment system that allows for quick sizing changes, ensuring a secure and adaptable fit.
