Independent tabulation Ochs Und Junior,  Founded in 2006 by table-making master Ludwig Ochslin,

The classic "Three Treatises on Astronomy" of Athens was authored by him, combining expertise in archaeology, astronomy, and physics.

The movement is an improved version of the Ulysse Nardin UN-320, with only 13 additional components for the full set of astronomical functions, achieving simplicity through complexity and bidding farewell to the obscure design of traditional astronomical watches.

The minimalist and understated design features a 40mm integrated short case with a five-grade titanium alloy, offering lightweight comfort and skin-friendly wear,

At first glance, it appears to be just an ordinary minimalist wristwatch, but inside it houses a full set of precision astronomical systems.

The floating layered dial features a cleverly designed golden and blue fan-shaped shutter day/night system: gold symbolizes daylight and blue represents night, automatically switching the duration of day and night for the four seasons every 10 days,

Visually display sunrise and sunset, noon, the positions of the sun and moon, lunar phases (new moon: the moon aligns with the sun; full moon: the moon is opposite the sun), and the date.

Wear it facing south, and the sun and moon indicators on the dial can align with the actual celestial phenomena in the sky. The six-position buttons allow adjustment to correct noon time.
