Breitling Premier Datora chronograph - 42MM - Ref : AB2510

The Breitling Premier Datora is a masterful interpretation of the classic calendar chronograph, featuring a moon-phase complication. With its heritage-inspired design, the Datora showcases rectangular chronograph pushers, Arabic numerals, syringe-style hands, and subtle grooves along the case sides. The open sapphire caseback offers a view of the finely crafted movement, highlighting Breitling’s attention to detail. Available in stainless steel with a copper dial or in 18k red gold with a silver dial, the Datora revives the name Breitling used in the 1940s to denote a complete calendar chronograph, displaying the day, date, month, and moon phase.

The stainless steel case measures 42mm in diameter, 15.3mm in thickness, and 50mm lug-to-lug, giving it a substantial presence on the wrist. The weight and thickness reflect the complexity of the automatic chronograph movement with calendar module, offering a commanding, yet refined feel.

Powering the Premier Datora is the COSC-certified Breitling B25 caliber, an automatic chronograph movement beating at 28,800 vph with an approximate 48-hour power reserve. The B25 is based on the Concepto C2000, a modern derivative of the Valjoux 7750, engineered by Concepto Watch Factory for efficient modular complications. Unlike lever-based movements, the B25 employs a vertical clutch layout with a column wheel, ensuring smooth chronograph operation and superior precision.

The Premier Datora perfectly balances heritage design with modern watchmaking excellence, making it a standout for collectors seeking a sophisticated calendar chronograph with technical prowess.
