Breitling Chronomat Automatic 40
About This Watch
The Breitling Chronomat Automatic 40 is a time-and-date variant of the iconic Chronomat collection, offering the signature rider tab bezel and Rouleaux bracelet in a versatile 40mm package without the chronograph complication. This makes for a slimmer, lighter watch that wears more like a daily companion than a specialized instrument. At 11.2mm thick, it slides easily under shirt cuffs — a notable advantage over the 15.1mm-thick B01 chronograph variant. The Breitling 17 movement, based on a proven Swiss base caliber with COSC certification, delivers reliable timekeeping with a 38-hour power reserve. With 200 meters of water resistance, the Chronomat 40 punches above its weight in terms of water capability, making it suitable for swimming, snorkeling, and water sports. The Rouleaux bracelet with micro-adjustment is one of the most comfortable in the industry, and the overall wearing experience is excellent for a sports watch in this size class. Priced below $5,000, the Chronomat Automatic 40 represents strong value in the luxury sports watch segment, offering distinctive Breitling design, genuine build quality, and everyday versatility at a price that undercuts many competitors. It is the ideal Chronomat for those who prioritize wearability.
In-Depth Review
# Breitling Chronomat Automatic 40 Editorial
Since its 1984 debut, the Chronomat has embodied Breitling's commitment to precision chronographs built for professional use. This 2021 iteration modernizes that legacy while maintaining the collection's defining characteristics: a robust stainless steel case, unidirectional bezel with distinctive rider tabs for gloved operation, and the in-house Caliber 17 movement. At 40mm, the case diameter strikes a contemporary balance between presence and wearability, while the 11.2mm thickness keeps the watch proportionate rather than chunky. The Rouleaux bracelet—Breitling's signature three-row design—adds visual complexity without sacrificing comfort, and the 200-meter water resistance adequately covers recreational diving and water sports without overengineering.
The Chronomat 40 appeals to collectors seeking functional horology without the premium pricing of luxury flagship brands. This watch serves equally well as a capable daily wearer and weekend tool, whether timing activities at the track or simply appreciating its mechanical precision through the exhibition caseback. The 38-hour power reserve provides practical everyday usability, and the date complication adds genuine utility without cluttering the black dial's clean layout.
In the sub-$4,000 market segment, the Chronomat competes directly with Tudor's Black Bay Chronograph and Longines' Hydroconquest. While the Tudor offers vintage aesthetic appeal at similar price points, the Breitling's heritage pedigree and in-house movement provide stronger horological substance. The Longines, meanwhile, prioritizes water resistance over chronograph capability. For buyers prioritizing professional-grade reliability within a reasonable budget, the Chronomat 40 remains the most compelling option.
