This clock face displays the time and date in the binary system, but you can easily learn to understand it.

Date - the columns of squares. The left one shows the day and the right one is the month.

Time - the columns of circles. The first two columns are hours, the second pair is minutes and the last is seconds.

Squares and circles represent numbers 1, 2, 4, 8, 16, from bottom to top. Just sum all the bright numbers - if the two bottom circles are bright, the column displays digit 3 (1 + 2). Hint at the last screenshot =)

The right bottom corner shows current weather - temperature with an icon. Information is updating once in hour.

The left bottom corner shows heart rate information. The heart icon flashes at the rate of your heartbeat. The color of the heart icon indicate your current heart rate zone (white - normal, yellow - fat burn, orange - cardio, red - peak)

Also, there are 11 color schemes. I tried to make them fit to some bands ^_^
