The H. Moser & Cie. Endeavour Tourbillon Skeleton: A Masterpiece of Elegance and Innovation

Among the diverse collections of H. Moser & Cie., the Endeavour stands out as a symbol of the brand's unique vision of elegance. This collection, which includes the sporty Pioneer, the integrated Streamliner, and a few Heritage watches, often incorporates a twist that sets it apart from the rest. Whether it's a pared-back "concept" dial or unexpected textures and colors, the Endeavour embodies a harmonious blend of classic and contemporary design.

This year, the Endeavour takes a bold step forward with the introduction of an open-worked flying tourbillon movement, seamlessly integrating the classic elegance of the Endeavour watch with the cutting-edge innovation of the HMC 814 in-house calibre. This calibre, derived from the HMC 804, boasts a solid power reserve of 72 hours and utilizes a bidirectional pawl winding system, ensuring optimal performance and reliability.

The Endeavour Tourbillon Skeleton showcases a fully open-worked movement, shared with the Streamliner collection, that is both transparent and symmetrical. The bridges and main plate, treated in an anthracite shade and adorned with drawn strokes, create a sleek and modern canvas that contrasts with the polished leaf-shaped hands and the applied hour markers, both gold-plated, for a modern yet classic look. Thanks to the use of different colors, legibility remains pretty good, at least for such a skeleton watch.

The watch measures a fairly reasonable 40mm in diameter, with an overall thickness of 10.7mm, and is crafted from 18k 5N red gold. It features a polished concave bezel, a conical crown, and elegant flanks that showcase the characteristic asymmetric forms of the collection, with vertically brushed elements contrasting with a polished groove. Sapphire crystals on both sides provide a clear view of the intricate movement.

The Endeavour Tourbillon Skeleton is powered by the Calibre HMC 814, an in-house automatic movement derived from the HMC 804. It maintains a solid power reserve of 72 hours and utilizes a bidirectional pawl winding system. Operating at 21,600 vibrations/hour, the HMC 814 comprises 167 components, including 28 jewels. All elements have been opened, including the barrel, offering a direct view of the spring, allowing the wearer to check that it is wound correctly. Finishing is pleasant, with polished bevels all around, even though some internal anglage would elevate this calibre to an even more appealing level.

The watch is released as part of the permanent collection and is priced at CHF 85,400 (incl. taxes). It is available in a dark brown alligator nubuck leather strap and features a 5N red gold pin buckle. For more information, please visit H-Moser.com.
