The time is not displayed as cyphers, however.
The face is a beautifully designed set of LEDs that mimic analog clock hands with concentric circles of light.
Gorgeous not only in looks, but also in user interface, the watch boasts an audible “tick” for each second, easy time-setting via the stem, and a custom alarm.
After 15 seconds, the watch goes into standby mode to save batteries.
When you open the face, it lights up again.
At each minute interval, it sets off a swirl of LED color!
Some additional deets: Paul wrote the program in C (and fit it in a 2KB code-size limit), used 133 surface mount LEDs, and engraved a tiger eye under the micro-chip.
