With the Endeavour Perpetual Moon Concept model, H Moser & Cie, a Swiss luxury watch brand, pays remarkable homage to the lunar body.

In 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 splendour.

The Endeavour Perpetual Moon Concept is one of the most precise moon phases available, with one day’s deviation every 1027 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. Regarded as the darkest substance of all, Vantablack is used in astrophysics in telescopes and by the army as thermal camouflage.

The Endeavour Perpetual Moon Concept in steel has an elegant, serene and refined moon phase display. It has a contemporary and bold design equipped with a black leather strap.

More sensual, the 5N red gold version features an H Moser & Cie midnight-blue fumé dial. Its deep lustres, with twilight tones, are perfectly matched with the red 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 calibre, equipped with an interchangeable Moser escapement. This calibre 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 1027.30 years, making it the most precise model available. 

The Endeavour Perpetual Moon Concept is available in a limited edition of 50 pieces for each of the two  references.
