The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin (ref. 4300V/220G-H119) is a 200-piece limited edition released in September 2026 to celebrate the Overseas collection's 30th anniversary. It pairs a 41.5mm 18k white-gold case, just 8.1mm thick, with a new lighter azure-blue lacquered dial and the in-house Calibre 1120 QP/1. US retail is $132,000.
Vacheron Constantin marks 30 years of the Overseas with its first-ever pairing of a white-gold case and azure dial. The new azure is lighter and less saturated than the deep Overseas blue introduced in 2016, reading more open-sky than deep-water and shifting with the light. A matching azure moon-phase disc keeps the dial cohesive, while applied 18k white-gold markers and hands carry blue Super-LumiNova. What makes it special? The self-winding Calibre 1120 QP/1 is only 4.05mm thick, allowing a full perpetual calendar with moon phase in an 8.1mm case. The calendar accounts for months of different lengths and leap years and needs no correction until 2100. The movement carries the Geneva Seal, and its 22k gold rotor is engraved with the Overseas compass rose. How is it delivered? With three tool-free interchangeable options: an integrated 18k white-gold bracelet with half-Maltese-cross links, plus white and denim-blue rubber straps with white-gold pin buckles. Is it limited? Yes. There are 200 individually numbered pieces, and they are expected to be allocated to established clients.
At 200 numbered pieces, this is the scarcest recent Overseas perpetual; the burgundy and gold-toned versions of 2025 were open production. The first white gold plus azure combination and the 30th-anniversary provenance should support strong secondary demand. The 40-hour power reserve is the main practical tradeoff.
