The Elegant Endeavour Tourbillon Skeleton by H. Moser & Cie Unveils a Refined Openworked Movement

Among H. Moser & Cie’s varied collections, which include the sporty Pioneer, avant-garde Streamliner, and traditional Heritage watches, the Endeavour holds a unique place as the brand’s representation of elegance, often carried out with an innovative spin. Whether it is a minimalist concept dial or surprising textures and hues, the Endeavour never fails to hold interest.

In 2024, the brand took a bold step by introducing an openworked flying tourbillon movement within the Endeavour’s case, a first for the collection. This was a blend of the classical elegance of the Endeavour and Moser’s in-house calibre HMC 814, debuted in the Streamliner collection. The HMC 814 superseded Moser’s former Tourbillon Skeleton movement, the HMC 811, boasting a reduced thickness thanks to the absence of a cylindrical hairspring and an off-centred display.

The openworked movement, shared with the Streamliner collection, is the watch’s pièce de résistance. Anthracite bridges on a sleek, modern canvas coexist harmoniously with gold-plated, polished leaf-shaped hands and applied hour markers. Located at six o’clock, a double hairspring-equipped flying tourbillon dominates the space and brings life to the dial.

Driving the Endeavour Tourbillon Skeleton is the HMC 814, an automatic calibre derived from the HMC 804. Despite its slim profile, it still delivers an impressive power reserve of 72 hours with the aid of a bidirectional pawl winding system. Comprising 167 components, including 28 jewels, it oscillates at a steady 21,600 vibrations per hour, testament to Moser’s commitment to precise, reliable timekeeping.
