General Overview
In 1990 Breguet introduced the modern Marine line (Ref. 3400). However, it was following the Swatch Group's acquisition of the brand that the collection truly came into its own. Introduced in 2004, the Reference 5817 modernized the sports watch concept for Breguet. It remained a staple of the brand's catalog until it was discontinued around 2018–2021, earning a cult status among collectors who appreciated its unique "breezy weekender" aesthetic.
Description and Conditions Report
Beautiful and Extra Full Set (Outer and Inner Box, Warranty and Booklets) example of Breguet Marine watch ref 5817ST. The Stainless steel case which measures 39mm offers an outstanding wrist presence without being oversized. The carrure features Breguet's iconic coin-fluted edge. Beautiful Guilloche Dial with blued handsset. Grande Date complication. Original rubber strap and deplo. Powered by the self-winding Breguet Calibre 517GG. This movement is built on a high-end Frederic Piguet 1150 base.
The Guillochè Dial
The Beautiful Guilloche Dial is constructed from a solid 18-karat gold plate which is then silver-coated. The center features a breathtaking, hand-executed "flame" or wave pattern cut using a traditional 19th-century rose lathe, the guilloché finishing. The dial is solid gold even in the stainless steel model.
This is one of the most remarkable details of the watch and a testament to Breguet's commitment to traditional haute horlogerie.
