Cretin. This reference represents a departure from the brand’s typical multi-axis tourbillons, featuring their first manual-winding time-only movement, the Calibre GFS1. Collectors value this model for its hand-finished architecture, including a large 12.6mm balance wheel and gold chatons, housed in a 41.4mm case. Production was strictly limited to 11 pieces in platinum with a blue dial, alongside 55 total pieces across other metals. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often between $150,000 and $220,000 depending on provenance. A notable auction result occurred at Christie’s in 2023, where a platinum example realized approximately $214,000, underscoring its rarity compared to the more common steel and gold variants.", "score": 204}]}
