Brute Rotating Earth and Moon Tourbillon

The time it takes for the Moon to rotate once on its axis is about 29 Earth days. This is a lunar day. For comparison, the Earth completes one rotation every 24 hours and the Moon completes one rotation every 709 hours.

In the watch, the Earth rotates accurately, 24 hours in real-time.

The Moon rotates in 60 seconds, just because it wouldnt be fun to wait 29 days to see it complete a full rotation.

This is an astronomy watch based on the Girard-Perregaux Bridges Cosmos watch.

To see the current moonphase tap the 3D moon, tap again to dismiss.
