Breitling Premier B25 Datora 42

Breitling's Premier B25 Datora 42, reference RB2510371G1P1, comes in an 18k red gold case measuring 42 mm across and 15.35 mm thick. It houses the self-winding calibre B25, a chronometer-certified movement with a 48-hour power reserve, and the dial sits under a cambered sapphire crystal treated on both sides against glare. As a chronograph, it combines a quarter-second chronograph function with a full calendar showing day, date, month and moon phase. The sapphire caseback is screwed in and left open to display the movement. A cream dial pairs with a brown alligator leather strap on a curved lug. The folding clasp, cast in red gold, closes on a case that stays water resistant to 100 metres.
