Clock with Equation of Time indication
After finishing the Hospice clock, the older clocks needed first some attention, but sometimes it is better to look than to touch, after maintenance the first clock refused to run for weeks! Suddenly everything was normal again but I had the idea that I had spoiled the clock a little bit, that's why I decided to make almost the same clock but now with Ball Bearings and a slightly different design.
Equation of Time is the difference between
mean Solar time and true Solar time.
Sometimes ahead, sometimes slower.
You can read the difference in time at the ring round the Sky map
