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

The Breguet Marine 5557BR/YS/9WV is a 43.90mm rose gold timepiece from the Marine collection featuring the Caliber 77F1 automatic movement with world time indication and day/night display across 24 time zones. The dial showcases hand-engraved Roman numerals and guilloché work in the Parisian tradition, while blued steel hands and hand-engraved case back complete the refined aesthetic. The lug width is 20mm, a standard size in haute horlogerie that ensures compatibility with high-end aftermarket straps.
