The Venus Annual Calendar is powered by the in-house CKM-01 movement, enhanced with a newly developed astronomical Venus module. Its dial is composed of four separate discs, three of which rotate to carry the celestial bodies — Venus, Earth and the Moon — displaying their real-time positions and orbits in a miniature planetarium. Set against a refined sunray-finished dial, an outer ring indicates the days of the month in a black and white railway track segmented by each month. Requiring only one correction every four years, all adjustments can be made conveniently via the crown.
