Watches usually don’t have a digital display which shows a battery status icon. As a result, users are informed about the weak battery in the least convenient moment: when they check the time and the watch hands are still.

Tissot has found a super-usable way to inform the user about a weak battery in the watch.

Let’s see how Tissot watch notifies about a weak battery. The idea is wonderfully simple. When the battery level is low, the second hand moves only every 4 seconds. It still shows correct time, but with lower frequency. Thanks to that, it uses less energy to move the hand and it tells the user the battery level is low.

The second hand moves every 4 seconds and still shows correct time.

I love the simplicity of this solution. Many other companies would work hard to design a separate place on the watch indicating the battery status. Tissot found a better way to do that.

Good job, Tissot!
