The Breitling Chronomat B31 Automatic 40 mm PB3114101C1S1 brings the clean three-hand design of the Chronomat B31 into a more refined configuration. Its 40 mm case keeps the watch balanced and wearable, while the blue dial gives it a deep, modern, and versatile character. The overall design remains true to the Chronomat identity, with a strong case profile, signature rider tabs on the bezel, and a dial layout focused on clarity rather than chronograph complexity.
This reference uses a simple time-and-date display, with the date positioned at 6 o’clock for a symmetrical and polished look. The blue dial, applied hour markers, and clean minute track give the watch a precise and elegant appearance, while the rubber strap adds a sportier and more comfortable feel for daily wear. The result is a Chronomat that feels modern, practical, and easy to wear, while still carrying the distinctive design language of the collection.
Inside the PB3114101C1S1 is Breitling’s Manufacture B31 automatic movement, visible through the sapphire crystal caseback. This movement gives the watch strong mechanical appeal while keeping the experience straightforward and practical. With 200 meters of water resistance, a robust construction, and the recognizable Chronomat design, this model offers a confident balance of refinement, durability, and everyday versatility.
