Constantın Grand Watch Face

This watch face combines moon phase, sunrise, sunset, daylight duration, solar time, and advanced astronomical complications into a single elegant design. Powered by real-time calculations, it blends science and aesthetics seamlessly.

Time is more than just hours and minutes. This watch face brings the rhythm of the sky to your wrist.

Designed beyond traditional watchmaking, it features advanced complications driven by real astronomical calculations:

🌙 Moon Phase – Realistic 29.5-day lunar cycle simulation
🌅 Sunrise & Sunset – Dynamically calculated throughout the year
☀️ Daylight Duration – Changes naturally with the seasons
🌍 Solar Time (Equation of Time) – Difference between solar and standard time
📐 Solar Elevation & Culmination – Sun’s position in the sky
🌗 Continuously evolving indicators reflecting seasonal shifts

All elements are mathematically modeled and evolve naturally over the year, just like in the real world.

The result:
Not just a watch face that tells time, but one that tells the story of time.

With its clean design and deep complexity, it delivers a truly premium and immersive experience.
