H. Moser & Cie. captures the mystery and splendour of the moon and its phases with two Endeavour Perpetual Moon Concept models. Nestled at the heart of the Concept dial, which features neither logo nor indices, is the eye-catching moon in a large window at 6 o’clock; a minimalist splendour like no other. The perpetual moon is not just an artistic masterstroke but also one of the most precise moon phases available, with one day’s deviation every 1027 years.
On the steel model, the dial is made from Vantablack. Its ultra-black coating, regarded as the darkest substance of all, is used in telescopes and by the army as thermal camouflage. It is composed of carbon nanotubes that are vertically aligned next to each other and is capable of absorbing 99.965% of light. It is the darkest black dial to be produced yet. The black colour is such that it appears astral, abyss-like: An undeniable black hole at the centre of which shines the moon. The steel model has a hand-stitched black leather strap.
A more sensual version features 5N red gold case with a midnight-blue fumé dial. Its deep lustres, with twilight tones, perfectly match the red gold of the case. A hand-stitched brown alligator leather strap adds the finishing touch. Both models have a 42 mm case with a height of 12.9 mm, Sapphire crystal on top, leaf-shaped hour and minute hands finished in the same colour as the case, and power reserve indicator on movement’s side. Both are limited to just 50 pieces.
The Endeavour Perpetual Moon Concept is powered by the HMC 801 hand-wound manufacture calibre, equipped with an interchangeable Moser escapement. This calibre ensures the watch has a minimum 7-day power reserve, with an indicator on the movement side. The moon phase system is an extremely accurate display that can be set, read and predicted to within a minute. The system can be easily adjusted using a push-button on the side of the case. On average, the moon’s orbital period lasts 29.53059 days. To be more precise: 29 days, 12 hours, 44 minutes and 2.9 seconds. The concept’s intricate wheel train portrays this interval so precisely that the gap is a mere 0.23 seconds per day, that is to say, one day’s deviation after 1027.30 years, which makes it the most precise model available.
The H. Moser Endeavour Perpetual Moon Concept represents technical complexity, is the embodiment of understated elegance and is worthy of the finest Haute Horlogerie traditions.
