Breitling Chronomat B01 42 Grey Dial Watch UB0134101B1U1

The Breitling Chronomat B01 42 Grey Dial (Ref. UB0134101B1U1) combines Breitling’s aviation heritage with luxury materials in a package that delivers legitimate chronograph capability. The stainless steel case with 18k red gold accents and grey dial creates visual warmth without being flashy, while the distinctive rider tabs provide actual crystal protection, not just aesthetic detail.

At 42mm with 15.1mm thickness, this wears substantially but proportionally for an aviation chronograph. The rider tabs give it unmistakable Chronomat identity and serve their original purpose of protecting the crystal during cockpit operations. The grey dial offers sophisticated contrast against the mixed metal construction without the boldness of traditional aviation colours.

Breitling’s Manufacture Calibre 01 delivers COSC chronometer certification with 70-hour power reserve, weekend-proof performance that exceeds most chronograph movements. The 1/4 second precision and proper 30-minute/12-hour totalisers make this genuinely useful for timing applications, not just aesthetic appeal.

The signature Rouleaux bracelet in mixed steel and gold feels substantial and secure, with the distinctive link construction that’s become synonymous with Breitling. At 204 grams total weight, it has the presence expected from a luxury aviation chronograph without being unwieldy.

This Chronomat suits buyers who want authentic aviation chronograph heritage with luxury finishing. The 1984 Chronomat marked mechanical chronographs’ comeback against quartz dominance, making this a piece of horological history. The mixed metals and grey dial create sophisticated appeal that works beyond aviation contexts, while the Manufacture movement and rider tab protection maintain the professional capability that made the Chronomat legendary.
