Breguet 5817BA Marine Big Date 18K Yellow Gold Silver Dial

The Breguet Marine 5817BA/12/5V8 is one of the most appealing expressions of the earlier Marine line, pairing the maison's classical dial craft with a more contemporary sporting case in 18K yellow gold. Its 39 mm proportions and screw-down crown give the watch genuine versatility, while the hand-guilloche silver dial preserves the unmistakable visual language collectors expect from Breguet. The oversized date display at 6 o'clock is integrated with unusual restraint, adding practical utility without disturbing the balance of the Roman numerals and blued Breguet hands. Inside is the automatic caliber 517 GG, a self-winding movement with a silicon balance spring and a substantial 65-hour power reserve, reflecting Breguet's steady move toward modern chronometric solutions. The sapphire back allows the movement to be appreciated in full, an important detail for buyers who value both finishing and mechanical substance. This reference belongs to the generation of Marine models that bridged Breguet's dress heritage and its nautical identity before the collection's later redesign, which gives it a distinct place in the line's evolution. The yellow gold case and silver dial configuration is especially attractive for collectors who want the warmth of precious metal without sacrificing the crisp legibility that defines the model. While not a limited edition for a specific country or boutique, it remains a reference with clear enthusiast appeal because it captures the most recognizable Marine cues in a compact and wearable format. For buyers drawn to Breguet's combination of historical legitimacy, technical refinement, and understated prestige, the 5817BA/12/5V8 stands as a highly compelling modern classic. Excellent Condition with Breguet box and papers dated 2021.
