The motion of our planet along its orbit and around the sun brings time to pass in our realities. We were quite intrigued by this fact and decided to recreate this idea in our next watch face.
Radii takes inspiration from the dynamics of a planetary system and simulates its workings onto a digital timepiece. The centre—our star—indicates the hour while a sphere carrying the minute rotates around it along its striped orbit. You will also see a tiny moon gliding around this sphere in sync with each stroke of the second hand.
What’s more? The watch face also has a scale that displays your battery life and a crescent that shows the day.
In the event that the watch does not automatically notify you to set up Radii you can manually do so by following these steps:
• On the watch, open Play Store
• Scroll down until the section "Apps on your phone" appears. You should be able to see Radii listed under this section.
• Under Radii, tap on "Install". Once it is installed, select "Set Watch Face".
