Breitling Chronomat

A Turning Point in Mechanical Watchmaking and an Aviation Legacy

The Breitling Chronomat name first entered the watch world in the 1940s with models featuring a slide rule to facilitate mathematical calculations. However, the model's modern identity was redefined in 1984 to mark the brand's centenary. During this era when the Swiss watch industry was emerging from the quartz crisis, the Chronomat was inspired by a special design developed for Frecce Tricolori, the aerobatics display team of the Italian Air Force; taking its name from the combination of the words "chronograph" and "automatic", it symbolized the resurgence of mechanical watchmaking.

The visual signature of the model is formed by four bezel rider tabs that protect the sapphire crystal against impacts and can be easily gripped even with gloves. Thanks to the removable and interchangeable tabs at the 3 and 9 o'clock positions, the rotating bezel can be set for both count-up and countdown timing. Featuring a characteristic onion crown and the Rouleaux bracelet that wraps around the wrist with its cylindrical links, the Chronomat design has become one of the most distinctive sport watch silhouettes of its era and today.

Manufacture Calibre B01 and the Evolution of Design Codes

Breitling introduced Caliber 01 (B01), its first in-house developed manufacture movement, for the first time inside the Chronomat case in 2009. Featuring a column wheel and vertical clutch architecture, this automatic movement offers high precision with an approximate 70-hour power reserve and a COSC chronometer certificate. Over time, the model family has expanded to a wide spectrum, from two-tone (steel-gold) 44 mm options like the CB0110 to the Super Chronomat series under reference AB0136, highlighted by ceramic bezel inserts and pushers. Additionally, non-chronograph alternatives like the Chronomat GMT 40 with reference A32398, which makes tracking a second time zone elegant, have found their place in the collection.

The technical structure of the watch is supported by a high water resistance rating, a robust screw-down crown, and balanced case architecture. Complementing the stainless steel case, the contrasting registers on the dial and intense lume filling on the hands transform the Chronomat from being merely a pilot watch into a versatile luxury sports watch identity.

Details to Consider When Buying Pre-Owned

When evaluating a pre-owned Chronomat, the screws on the bezel rider tabs should be meticulously inspected for wear or deformation. The crispness of the rotating bezel click mechanism, the condition of the threads on the screw-down crown, and the firmness of the chronograph pushers provide important clues about the watch's mechanical condition. On models with the original Rouleaux bracelet, stretch between the links and a firm clasp locking mechanism are critical factors for comfort.

Having a full box and papers set provides a major advantage for verifying the past service history, especially on models with the manufacture B01 movement and GMT calibre.
