It is no longer in production. Collectors value this reference for its cushion-shaped 18k white gold case, which measures 40mm by 49.3mm, and its use of the manufacture caliber 2460DT. This self-winding movement features a second time zone sub-dial at 4 o’clock and a day-night indicator at 8 o’clock, all adjustable via the crown. The silvered opaline dial includes blue painted Arabic numerals and leaf-shaped hands. A distinguishing feature of this anniversary edition is the balance cock, which is hand-engraved with a scrolling \"fleurisanne\" motif inspired by a 1755 pocket watch. On the secondary market, this reference typically trades between $25,000 and $35,000. A smaller 37mm version set with diamonds, reference 7805S, was produced concurrently for women."}, "listing_stats": {"count": 8, "median": 37487.5, "low": 26950.0, "high": 433030.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_8029562765634", "title": "Vacheron Constantin Harmony SplitÐSeconds Chronograph Ultra-Thin Ref. #
