Watch Info
Manufacturer: Breguet
Model: Marine Big Date
Condition: Pristine (Pre-Owned)
Reference: 5817ST/Y2/5V8
Year: Produced circa 2004–2018 (Original papers undated)
Box: No
Papers: Yes
Accessories: Watch and Papers Only. Includes the original Breguet warranty booklet/certificate and the blue rubber strap with a stainless steel deployant clasp.
Notes: The 5817ST is a modern masterpiece that successfully blends Breguet’s 18th-century horological codes with a 21st-century "sport-luxe" aesthetic. This specific iteration—featuring the royal blue dial—is arguably the most sought-after stainless steel configuration. The dial is made of solid gold and then hand-engraved on a rose engine to create its signature "wave" guilloché pattern, a testament to the brand's commitment to high-level craftsmanship.
Condition Assessment
Overall Condition: Pre-Owned - Pristine. Despite being "Watch and Papers only," this example appears to have been a "safe queen." It shows no significant signs of wear, with sharp, untouched coining on the case flanks and flawless high-polish surfaces.
Dial, Hands, & Crystal: The blue guilloché dial is perfect, with the silvered Roman numeral indices and "Breguet" tipped hands providing exceptional legibility. The sapphire crystal is immaculate, and the exhibition caseback offers a clear view of the masterfully finished movement.
Case & Bezel: The 39mm stainless steel case is in pristine condition. The characteristic fluted (coined) case middle is crisp, and the polished bezel is free of the typical "desk-diving" marks often seen on this reference.
Strap & Clasp: The integrated blue rubber strap is supple and in excellent condition. The original stainless steel folding deployant clasp—shaped like the Breguet "B"—functions perfectly and shows no visible scratches.

Case Material: Stainless Steel
Movement: Calibre 517GG (Automatic, 11.5 lines, 35 jewels)
Power Reserve: Approximately 65 Hours

Why the 5817ST Blue Dial is an Enthusiast Favorite
The 5817ST is often cited as one of the best "value" propositions in high horology. While the newer 5517 reference is technically impressive, many collectors prefer the 5817 for its more traditional Breguet DNA, specifically the hand-guided guilloché and the unique "Big Date" complication.
This specific blue dial variant is particularly rare to find in Pristine condition. Because it is a "Watch and Papers" set, it offers an attractive entry point for a collector who prioritizes the watch's mechanical integrity and official provenance over the bulky wooden presentation box. In the current 2026 market, the blue dial 5817ST continues to hold its value significantly better than its silver or black counterparts, representing a sophisticated alternative to the more common steel divers from other brands.
