The Agelocer Astronomer

Description

The Moon's cyclical orbit around Earth, with its ever-shifting phases, has long been regarded as astronomy's most romantic phenomenon, and horology's most enduring complication.

The Agelocer Astronomer Watch introduces a new large-aperture moon-phase mechanism featuring a single, fully visible moon disc.

The complication adheres to the precise 29.53-day lunar cycle, with an accuracy that deviates by just one day every 122.5 years.

Unlike conventional large-aperture moon-phase displays, the in-house Caliber A6001 automatic movement incorporates a variable-speed moon disc—its angular velocity accelerates, then decelerates, following a cosine curve derived from trigonometric calculations. This motion works in concert with the circular moon-phase aperture, allowing the terminator line to traverse the moon's surface with natural, fluid precision. This approach liberates the aperture from the heart-shaped curves typically required by traditional calculations. By adjusting the moon disc's rotation speed, different aperture profiles become possible, opening new avenues for large-aperture moon-phase design and expanding both form and application.

The moon disc itself carries an embedded three-dimensional metallic micro-sculpture, faithfully reproducing the lunar topography. Coated with Super-LumiNova, it appears subdued by day and glows like a full moon on the wrist by night, capturing the texture and presence of the real celestial body. Dial markers and lettering are executed in raised metal relief with fine brushed finishing, while the moon-phase window features chamfered and polished edges. Each layer of detail builds depth, playing with light and shadow to achieve a quietly refined sophistication.
