Breguet Marine

The Breguet Marine Automatic Big Date, reference 5817ST/12/SV0, is a timepiece that distils everything Abraham-Louis Breguet stood for into a watch built for the pleasures of modern life on and around the water, combining his legendary aesthetic language with a technical sophistication that is entirely of our time. This certified pre-owned example from 2018 is offered in excellent condition and comes with its full original set, including box, papers, and all original accessories. Crafted in stainless steel, the 5817ST presents the Marine collection in a beautifully refined 39mm round case measuring just 11.9mm in height, with a fluted case edge, a screw-down crown, and a sapphire crystal caseback revealing the exquisitely finished movement within. The hand-guilloché silver dial is a work of art in itself, with its engine-turned centre creating a pattern of extraordinary depth and texture, framed by applied blued steel Roman numeral hour markers and the signature Breguet "full apple" hands in 18k gold. The grande date display at 6 o'clock, showing the date through two adjacent apertures in a generously proportioned format, adds both practicality and visual drama in equal measure. Powering the watch is the Breguet Calibre 517GG, a fully in-house automatic movement with a flat silicon spiral escapement, 285 components, 35 jewels, and an exceptional 65-hour power reserve. A movement that combines Breguet's centuries-old horological heritage with the precision materials of modern manufacture watchmaking. The watch is fitted with the signature Breguet stainless steel link bracelet with folding clasp.
