Moser & Cie. Henry Double Hairspring, reference 324.607, was produced in the late 2000s, specifically around 2008 to 2011, and is no longer in production. Collectors target this reference for its tonneau-shaped case crafted from 950 palladium and the manual-wind Calibre HMC 324.111. This movement features a Straumann Double Hairspring designed to compensate for gravitational errors without a tourbillon, alongside a power reserve indicator and a functional interchangeable escapement module. The dial typically features a fumé finish with Roman numerals and a sub-seconds register. Due to low production volumes, these pieces appear infrequently on the secondary market, generally commanding prices between $15,000 and $22,000 depending on condition. A notable production detail is that this model represents one of the few instances where the brand utilized palladium before transitioning primarily to gold and steel for its contemporary collections."}, "listing_stats": {"count": 2, "median": 61050.0, "low": 24100.0, "high": 98000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7428602101969", "title": "H.
