FAQ

Chronos works with all Apple devices running iOS 8.0+ (with Android coming soon!) You can download the app for free in the Apple App Store and the Google Play Store.

Are there magnets in Chronos that could affect the expensive movement in my watch?

No. We have carefully avoided the use of magnets that could interfere and damage the movement inside the watches we love. Instead, we use harmless microsuction to attach to the back of your timepiece.
