The Marine 5557BB/YS/9WV, seen from the bench

The Breguet Marine 5557 in white gold features a 43.90mm case housing the Breguet Caliber 77F1 automatic movement with world time, date, and day/night indication. The white gold case with guilloché dial and fluted bezel reflects the brand's marine chronometer heritage since 1815. The watch comes with integrated white gold bracelet and requires a 20mm curved-end strap for proper fit and transition at the horns.
