This reference is valued for its use of the Caliber 591, an ultra-thin automatic movement based on the Lemania 8810 with twin barrels. The 35mm case features traditional Breguet design elements, including a coin-edge mid-case, straight lugs with screw-pins, and a solid gold dial decorated with hand-turned engine guilloché. Collectors prioritize this model for its chronometer certification and its representation of the Daniel Roth era of design. On the secondary market, this reference typically trades between $8,000 and $12,000 depending on the presence of original documentation. A notable production detail is the inclusion of an individual serial number on the dial, a practice consistent with historical Breguet marine chronometers.", "score": 200}]}
