This reference is distinguished by its 40mm compressor-style snap-back case, which replaced the earlier screw-back designs to improve water resistance. Collectors prioritize this model for its Valjoux 724 movement, a modified version of the manual-wind Valjoux 72 featuring a GMT complication. The dial typically features three sub-registers and a red GMT hand, paired with a bidirectional rotating bezel available in \"Pepsi\" red and blue or \"Coke\" red and black color schemes. Current secondary market prices generally range from $12,000 to $20,000 depending on condition and bezel preservation. A notable production variant is the \"Mark 4\" dial, which features polished steel hour markers with luminous inserts. These watches are frequently found with \"Gay Frères\" beads-of-rice bracelets, which significantly impact the final valuation for collectors.", "score": 200}]}
