H. Moser & Cie. Endeavour Tourbillon Concept Vantablack White Gold

This new H. Moser & Cie. Endeavour Tourbillon Concept watch in white gold proudly displays one of the most complex and most traditional mechanisms in Haute Horlogerie on a super-black dial made from Vantablack.

Positioned at 6 o’clock, the one-minute flying tourbillon seems literally to float in the centre of a black hole, with no reflection, and without indices or logo by way of distraction. H. Moser & Cie. has given its Endeavour Tourbillon Concept a dial made from Vantablack®, employing all the expertise it has gained by working with this innovative material created in 2012.

A super-black coating renowned as the darkest substance in existence, Vantablack® is composed of carbon nanotubes that are 10,000 times finer than a human hair, aligned vertically alongside each other. When a photon hits Vantablack®, this material absorbs 99.965% of the light. As our eyes need reflected light to perceive what we are looking at, Vantablack® is perceived as the absence of matter, a black hole.

With the Endeavour Tourbillon Concept Vantablack®, H. Moser & Cie. is writing an ode to minimalism. The simple look of the watch complements the complexity of the materials chosen and the HMC 804 Manufacture movement equipping this model.

In addition to Vantablack®, the Schaffhausen-based Manufacture used aluminium borrowed from the aerospace industry for the cage of its tourbillon, including the cage wheel, the balance bridge and the escapement bridge. More rigid than traditional aluminium, this innovative material offers the advantage of being more lightweight than brass.

The result is reduced inertia, which offers an improved energy balance, and also enhanced performance with optimal operation and more stable isochronism over the long term. There is also an increase in the amplitude of approximately 10%. With its characteristic attention to detail, H. Moser & Cie. has added a black PVD coating to the tourbillon bridge and to the balance bridge, which echoes the abyss-like black of the Vantablack® dial.

The self-winding HMC 804 calibre incorporates a double hairspring designed and produced in-house. Thanks to this pair of matched hairsprings, the movement of the point of gravity on each spring when it expands is corrected and the effect of friction reduced, significantly improving accuracy and isochronism in continual pursuit of perfection.
