Minimal and orbital. Three outsized gear wheels tell the time:
the largest shows the minutes and the smallest, at the centre,
the hours. Both of them, turning around the central axis, interact
with a third wheel, the upper and lower teeth of which have
been calculated so as to turn the minute wheel once an hour
and the hour wheel twice every 24 hours. No crown disturbs
the pared-down aesthetics of this watch, the setting mechanism
of which is on the case back. A fine achievement.
