H. Moser & Cie Endeavour Tourbillon Concept

About this reference

The H. Moser & Cie. Endeavour Tourbillon Concept reference 1804-1201 was released in 2018 as a limited edition of 20 pieces and is no longer in production. This reference is distinguished by its 42mm stainless steel case, a material rarely used by the brand for tourbillon complications, which are typically reserved for precious metals. It features the HMC 804 self-winding manufacture movement, equipped with a double hairspring and a one-minute flying tourbillon visible at six o'clock. The "Concept" designation indicates the absence of a logo or indices on the Funky Blue fumé dial, emphasizing minimalist aesthetics. Collectors value this model for its combination of a high-complication movement with a utilitarian steel case and the brand’s signature stripped-back design language. On the secondary market, this reference typically trades in the $55,000 to $75,000 range. A similar steel-cased Concept tourbillon achieved approximately $63,000 at a 2022 Christie’s auction.
