Sprie Metric is an attempt to show the so-called Metric Time.
In metric time, a day is diveded in 10 hours, while every hour is divided in 100 minutes, who in turn exist of 100 seconds each.
Sprie Metric offers the choice between the real metric time, and a AM/PM variant, in which a day counts 20 hours, rather than 10.
There are 3 modes, that can be accessed by tapping the centre:
- The default metric mode, with the normal digital time at the bottom of the dial
- The AM/PM metric mode, with the normal digital time at the bottom of the dial
- The usual analogue time, with the metric time at the bottom of the dial.
