Unworn Breitling Chronomat B01 Chronograph 42, Stainless steel and 18k Red Gold, Ref# UB0158101B1U1, box and papers

Introducing the unworn 2026 Breitling Chronomat B01 Chronograph 42, Ref# UB0158101B1U1—a modern interpretation of one of Breitling’s most recognizable sports chronographs, combining strong technical performance with a refined, versatile design. The latest-generation Chronomat retains the character that made the collection famous while bringing a cleaner, more contemporary presence to the wrist. The 42mm stainless steel case offers a confident yet well-balanced profile, measuring 13.77mm thick. Its signature unidirectional-ratcheted 18k Red Gold bezel, distinguished by four raised rider tabs, remains one of the defining features of the Chronomat. A screw-locked 18k Red Gold crown with two gaskets and scratch-resistant sapphire crystal reinforce the watch’s robust construction. The striking Grey sunray dial combines a clean, highly functional layout with the unmistakable Breitling aesthetic. Contrasting polished 18k Red Gold hands and applied polished 18k Red Gold hour markers, all enhanced with extremely visible luminous fill, provide exceptional legibility at a glance. Three contrasting black chronograph sub-dials create a bold visual balance, while the small-seconds counter at 9 o’clock and the 30-minute and 12-hour chronograph counters ensure precise reading of elapsed time. A black dial flange with a tachymeter scale and finely printed minute/seconds track frames the display, adding a distinctly sporty touch. The date window at 6 o’clock provides everyday practicality without disrupting the harmonious design. Protected by scratch-resistant sapphire crystal, the dial is complemented by a sapphire crystal case back, offering a view of the sophisticated mechanical movement within. At the heart of the watch is the Breitling Manufacture Calibre 01, a self-winding mechanical chronograph movement renowned for its precision and reliability. Operating at 28,800 vibrations per hour, the movement features 47 jewels, measures elapsed time to 1/4 second with 30-minute and 12-hour counters, and provides an impressive 70-hour power reserve. As a COSC-certified chronometer, it meets strict standards for mechanical precision. Breitling’s distinctive integrated Rouleaux Stainless Steel and 18k Red Gold bracelet, whose rounded links give the Chronomat its characteristic combination of sporty strength and refined comfort, complete the watch. Micro-adjustment on both sides of the clasp allows for a more precise fit on the wrist. With 200-meter water resistance, the 2026 Chronomat B01 Chronograph 42 is built for versatility—from everyday wear to more demanding environments. It brings together Breitling’s aviation-inspired heritage, in-house chronograph technology, and unmistakable contemporary design in one exceptionally capable timepiece.
