H. Moser & Cie: Endeavour Tourbillon Skeleton

For H. Moser & Cie., minimalism is not an aesthetic choice but a design philosophy. To remove in order to reveal, to strip away the superfluous and expose the mechanism itself. It is a principle that defines the brand’s identity and finds one of its most coherent expressions in the new Endeavour Tourbillon Skeleton: a fully skeletonised watch conceived to retain only what is essential.

Before the eyes, time takes shape through the motion of the one-minute flying tourbillon with double hairspring, visually suspended in space. The 40 mm 5N red gold case frames this mechanical architecture with restraint and balance, turning the Endeavour Tourbillon Skeleton into a controlled synthesis of technique and style.

TRANSPARENCY, LIGHT AND SYMMETRY

Transparency and symmetry guide the entire design of the Endeavour Tourbillon Skeleton. Its structure is conceived to allow light to circulate, reveal the depth of the movement, and deliver a sense of clarity that has become increasingly rare in contemporary watchmaking.

Through the fully skeletonised dial, the movement is revealed without filters, pushing legibility to its limits. Anthracite-coloured bridges and mainplate, decorated with the traits tirés motif, define a clean, contemporary geometry with an almost architectural character. Leaf-shaped hands and gold-plated indices introduce a measured contrast, adding warmth and recalling a classicism reinterpreted in a contemporary idiom.

FLYING TOURBILLON AND DOUBLE HAIRSPRING: THE ARCHITECTURE OF TIME

At 6 o’clock, the flying tourbillon asserts its presence with discretion. It does not dominate; instead, it marks the passage of time with regularity, reminding us that behind its apparent lightness lies a construction oriented towards precision and longevity.

The skeletonised automatic HMC 814 calibre, offering a 72-hour power reserve, integrates a double hairspring designed and manufactured in-house by Precision Engineering AG, an affiliate of H. Moser & Cie. The two hairsprings work in a complementary manner. They correct shifts in the centre of gravity during expansion and reduce friction. The result is a tangible improvement in precision and isochronism, reflecting an ongoing pursuit of technical refinement.

The openworked barrel offers a direct view of the mainspring, allowing its state of wind to be checked – an element that is as functional as it is visual. The rotor follows the same principle and is fully skeletonised, consistent with the overall architecture of the movement.

PROPORTIONS AND IDENTITY OF THE ENDEAVOUR TOURBILLON SKELETON

Housed in a 40 mm 5N red gold case, the Endeavour Tourbillon Skeleton maintains balanced proportions and a restrained presence on the wrist. The caseband features the characteristic asymmetrical lines of the Endeavour collection, a distinctive element that reinforces the model’s identity.

It is a watch that embraces its technical complexity and chooses moderation as its language. In a context that tends to add, this timepiece chooses subtraction – not to simplify, but to reveal what truly matters.

The brown nubuck alligator leather strap, paired with a 5N red gold pin buckle, completes the ensemble with coherence and restraint. Price: CHF 79,000 + taxes.
