This is a precision panoramic large aperture moon phase automatic mechanical watch crafted from blue aventurine, the material that most closely resembles the starry night sky, designed by Swiss chief designer Etienne Ruffieux, inspired by the sun, moon, and stars. The intricately carved luminous moon changes once daily, fully showcasing the entire cycle of nature's waxing and waning phases. This watch has been awarded the European Design Award for its outstanding original design.
In-house CAL.A4610 fully automatic mechanical movement, bidirectional automatic winding system, 28,880 vibrations per hour, 27 ruby bearings. Exquisite perlage and geneva stripes finishing, edge chamfering process, white gold plating, and engraved gold-plated brand logo. Delivers an extended 80-hour power reserve (twice that of standard mechanical movements). This technology enables a more even and gradual release of the mainspring, resulting in more precise and stable timekeeping.
The moon phase disc in Agelocer's in-house CAL.A4610 automatic mechanical movement features a precision 31-tooth structure. It advances one segment every 22.846 hours, completing a full cycle every 29.51 days to achieve a 708.23-hour lunar cycle. (Conventional moon phase discs use a 59-tooth gear, advancing one notch every 24 hours to complete a full cycle in 29.5 days, resulting in a 708-hour lunar cycle.)
The astronomical lunar cycle is 29.53 days (708.72 hours), meaning conventional moon phases accumulate a one-day error every 2.7 years. The Agelocer moon phase watch accumulates one day of error every 4.1 years, offering greater precision than traditional 59-tooth moon phase mechanisms.
The dial is made of natural blue aventurine from Brazil. Its deep blue or violet-blue color from scaly vivianite contained within quartz crystals during geological formation. It shimmers with a beautiful, soft glow, like sky full of stars, make it most star-like natural dial material available today. In this panoramic large moon phase watch, as the dynamic moon perfectly glides across the starry surface of the blue aventurine dial, it feels as if the cosmic starry sky is right before your eyes.
The moon takes center stage in this timepiece. To bring it to life on the wrist, we employed precision metal engraving techniques, enhanced with an expensive platinum-plating process to render the moon's texture strikingly lifelike. To ensure the moon radiates brilliance even in darkness, we selected Swiss Super-LumiNova luminous coating. Its luminous effect cycles infinitely has no time limit. This uncompromising pursuit exists to showcase the moon's most captivating aspect as it rotates.
