Premier B25 Datora 42

It is one of the most sophisticated models in Breitling's elegant Premier collection—a 42 mm chronograph that adds a complete calendar (day, date and month) together with a moonphase display. "Datora" is a historic Breitling name from the 1940s for this calendar-chronograph format, revived as part of the Premier Heritage line. With its refined dress-watch styling, in-house movement and balanced dial, the Premier B25 Datora 42 is positioned as a connoisseur's piece that blends everyday elegance with genuine horological complication.

This reference is a 42 mm stainless-steel case, with an 18k red-gold execution also offered in the Premier collection. It is best known for its warm copper-toned (salmon) dial, framed by Arabic numerals and a syringe-style handset, with the calendar apertures and moonphase integrated into a balanced layout. A cambered sapphire crystal with anti-reflective coating protects the dial, and the watch is worn on a semi-shiny alligator leather strap, reinforcing its elegant, dress-oriented character.

It is driven by the Breitling Manufacture Caliber B25, an automatic chronograph movement that integrates a complete calendar and moonphase. It offers around 70 hours of power reserve and is officially COSC-certified as a chronometer, guaranteeing accuracy of -4/+6 seconds per day. The B25 belongs to Breitling's family of in-house Premier calibers (alongside the Manufacture Caliber 01 chronograph and B09 hand-wound), bringing manufacture credibility to one of the line's most complication-rich watches.
