More information
A refined yet sporty take on the Marine line, this 5817ST pairs Breguet’s signature coin-edge steel case and hand-guilloché dial with a practical big date at 6 o’clock and a screw-down crown for real-world utility. Inside, the automatic calibre 517GG delivers a robust and elegant finishing, visible through the sapphire display back. On its rubber strap with folding clasp, the watch balances daily wearability with classic Breguet details.
