Breguet 5557BB Marine Hora Mundi 18K White Gold Blue Dial

The Breguet Marine Hora Mundi reference 5557BB/YS/5WV is a masterful expression of haute horlogerie, marrying technical ingenuity with maritime elegance. Housed in a 43.9 mm 18‑carat white gold case with a slim 13.8 mm profile, this world‑timer was the product of three years of development and secured four patents for its instant‑jump dual time‑zone mechanism. The galvanic blue, hand‑guilloché dial features a layered world‑map motif rendered in gold and sapphire, complete with a day/night indicator, retrograde date, and city disc, all powered by the in‑house automatic Calibre 77F1 with silicon escapement and 55‑hour power reserve. Water‑resistant to 10 bar, the watch balances real‑world durability with refined aesthetics. Its blue rubber strap, secured by a white gold triple‑blade deployant clasp, underscores the Marine collection’s sporty yet sophisticated character. This reference stands as a compelling choice for seasoned collectors seeking a rare, mechanically advanced timepiece that honors Breguet’s navigational heritage.
