Clock mechanism of an Anniversary Clock

History
Around 1880, a German clock maker, Anton Harder, patented a torsion suspension clock that worked for a year with just one winding. These "anniversary clocks" were also called "400-day clocks" and "1,000-day clocks" to indicate winding frequency.

Today battery operation has replaced physical winding, although the basic mechanical principles remain intact. "Anniversary clocks" still stands, because in most cases, the batteries need replacing about once a year.


We were much later returning from Nelson than I expected- so a very late blip.
