Heuer Autavia GMT

About this reference

The Heuer Autavia GMT reference 2446C was produced from approximately 1968 through the early 1970s. 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.
