This model utilizes the Valjoux 72 movement, modified with a tide indication complication displayed via a subdial at nine o'clock. Collectors prioritize this reference for its use of the second-execution Autavia compressor case, featuring a snap-on back and a rotating bezel marked with tide intervals. The dial is characterized by its white registers against a black background, specifically designed for maritime use. Production numbers were low, making it rarer than standard Autavia chronographs of the same era. On the secondary market, prices typically range from $50,000 to $90,000 depending on condition and provenance. A notable production detail is the \"SF\" designation, which stands for Seafarer, reflecting its relationship with the Abercrombie & Fitch branded versions of the same movement and case architecture.", "score": 201}]}
