Collectors prioritize this reference for its automatic Calibre 15 movement, which features an offset small seconds sub-dial at the ten o'clock position, distinguishing it from the earlier Calibre 12 versions. The 42mm stainless steel \"Autavia-style\" compressor case houses a blue dial with a specialized fifteen-minute regatta countdown timer divided into five-minute segments of red, white, and blue. This reference is valued for its specific tool-watch functionality and its transition from the earlier manual-wind models to the automatic era. Current secondary market prices typically range from $12,000 to $18,000 depending on condition and bracelet originality. A notable production variant includes the \"early\" 1564 models which utilized the 1163V case before the reference transitioned to the 15640 designation with an integrated mineral crystal and updated bezel.", "score": 199}]}
