Pre-owned Breitling Premier B25 Datora 42 ref RB2510371G1P1 (2024) shows a different side of the brand, one focused less on cockpit instruments and more on classic watchmaking. The watch is crafted from 18k red gold and measures 42mm, with vintage-style rectangular chronograph pushers and subtle grooves along the case sides that pay homage to Breitling designs from the 1940s. The silver dial carries a full calendar layout with day, date, and month displays, along with a moon phase tucked neatly above 6 o’clock. Despite the number of indications, the dial is still balanced and easy to read thanks to applied Arabic numerals and elegant syringe-style hands. Inside is Breitling’s in-house caliber B25 automatic movement, a COSC-certified chronograph meant to handle the added complexity of a complete calendar. Paired with a brown alligator strap and with an exhibition-style case back, the Datora feels more like a traditional Swiss complication than a modern tool watch, and proof that Breitling’s history extends well beyond aviation chronographs.
