The dial is characterized by three sub-dials with red tachymetric scales, and the case utilizes a unique rocker-actuator at the 2 o’clock position rather than traditional pushers to control the chronograph functions. Early examples often feature \"shiny\" dials that are highly sought after for their specific texture. On the secondary market, this reference typically trades in the $100,000 to $160,000 range.

Collectors prioritize this reference for its Calibre GF01c movement, which features a fast-rotating tourbillon inclined at a 25-degree angle to compensate for gravity in various positions. The design is distinguished by its multi-level dial architecture, featuring a transparent synthetic sapphire hour-circle and a prominent power reserve indicator at 4 o'clock. The 43.5mm case houses a movement with 267 components and a 72-hour power reserve. This specific rose gold execution was limited to 33 pieces, contributing to its scarcity.
