Fascinating, mysterious: People have always found the moon captivating. With the Endeavour Perpetual Moon Concept model, H. Moser & Cie. pays remarkable homage to the lunar body. With two resolutely contemporary models, H. Moser & Cie. reinterprets the most poetic complication ever; showcasing the eye-catching moon in a large window at 6 o'clock, in all its splendor. A perpetual moon, the Endeavour Perpetual Moon Concept is one of the most precise moon phases available, with one day's deviation every 1,027 years.

By reinterpreting the moon phase in such an understated way, H. Moser & Cie. highlights the beauty of the lunar body in an ode to its purity. Nestled at the heart of the Concept dial, which features neither logo nor indices, the moon shines through in a large window at 6 o'clock. Surrounding it there is only space, seemingly interplanetary space.

This effect is enhanced by the dial which is made from Vantablack for the steel model. Its ultra-black coating, regarded as the darkest substance of all, Vantablack is used in astrophysics 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 color is such that it appears astral, abyss-like: An undeniable black hole at the center of which shines the moon. The Endeavour Perpetual Moon Concept in steel has an elegant, serene and refined moon phase display. A contemporary and bold design equipped with a black leather strap.

More sensual, the rose gold version features an H. Moser & Cie. midnight-blue fumé dial. Its deep luster, with twilight tones, are perfectly matched with the rose gold of the case. A brown alligator leather strap adds the finishing touch.

The Endeavour Perpetual Moon Concept is powered by the HMC 801 hand-wound manufacture caliber, equipped with an interchangeable Moser escapement. This caliber ensures the watch has a minimum seven-day power reserve, with an indicator on the movement side.

The moon phase system is an extremely precise 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 Endeavour Perpetual Moon 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 1,027.30 years, making it the most precise model available.

The H. Moser Endeavour Perpetual Moon Concept embodies technical complexity, is unconditionally elegant and understated and worthy of the finest watchmaking traditions. Available in steel or rose gold, the Endeavour Perpetual Moon Concept is available in a limited edition of 50 pieces for each of the two references.

The unmistakable H. Moser style of irreverent haute horlogerie.
