Endeavour Tourbillon Concept Turquoise Enamel is reference 1805-0400, a 40 mm 5N red-gold watch pairing a turquoise fumé Grand Feu enamel dial with the automatic HMC 805 movement and a one-minute flying tourbillon. H. Moser & Cie. lists it at CHF 75,000 excluding VAT.
What is the Endeavour Tourbillon Concept Turquoise Enamel?
Reference 1805-0400 is a 2025 novelty, according to the Fondation Haute Horlogerie (FHH). Its design combines an intentionally spare dial with a prominent mechanical complication: the FHH describes the face as having no logo and no markers, while the movement includes a flying tourbillon.
The case is 40.0 mm across and made of 5N red gold. FHH lists its thickness as 11.20 mm and identifies a sapphire caseback. H. Moser & Cie. specifies 3 ATM water resistance; that rating alone should not be taken as a swimming recommendation. The listed strap is hand-stitched grey ostrich leather.
How is the turquoise enamel dial made?
The turquoise fumé dial is Grand Feu enamel applied over a hammered white-gold base. FHH describes three shades of translucent enamel applied in successive layers to create the gradient. The result is a color treatment that shifts from brighter turquoise toward darker tones; H. Moser & Cie. characterizes its appearance as moving between depth and transparency.

The dial’s lack of a logo or hour markers keeps the surface visually open, placing the enamel and the tourbillon in the foreground. Hours and minutes are the functions listed by FHH.
What movement is inside?
The watch uses H. Moser & Cie.’s automatic HMC 805 calibre, which the manufacturer says replaces the earlier HMC 804. Its listed power reserve is 72 hours. The movement has a one-minute flying tourbillon fitted with a double hairspring.

H. Moser & Cie. describes the calibre’s partially skeletonised bridges, anthracite-grey finishing, visible gear train and bidirectional winding wheels, as well as a bevelled rotor. FHH says the matched balance springs are made by Moser’s sister company, Precision Engineering AG. It explains that correcting each spring’s centre of gravity as it expands reduces friction and is intended to improve precision and isochronism. These are descriptions of the design; the reviewed sources do not provide timing-test results for this individual watch.
