H. Moser & Cie. has announced the Endeavour Perpetual Moon Concept Aventurine. Featuring a beautifully shimmering aventurine dial, the Moon and Stars model exudes minimalist aesthetics and rich poetry with its moon phase display that celebrates the moon.
H. Moser without indices or logos
A silvery moon is waxing in a beautifully proportioned window at 6 o'clock. It is an innovative yet understated expression of the moon. H. Moser & Cie. has combined this pure, poetic design with a concept dial that is devoid of indexes and logos, allowing for a completely free expression of the moon's appearance. Furthermore, to enhance the beauty of the moon, an aventurine dial with fine particles that sparkle like constellations floating in the night sky has been adopted.
The moon phase deviates by just 1 day every 1027 years

The Endeavour Perpetual Moon Concept Aventurine is equipped with one of the most accurate moon phase functions, with an accuracy of just one day every 1027 years. This moon phase constantly moves in tandem with the hour hand, varying only 0.23 seconds per day from the actual lunar cycle. The in-house hand-wound caliber HMC801 features Moser's unique modular escapement, ensuring a power reserve of at least seven days, and its display is located on the case back. The moon phase display system is extremely precise, being able to be set to within one minute. It can be easily adjusted using a push-button on the side of the case, and the small, arrow-shaped central seconds hand serves as a 24-hour display.
