I will be brief, today. I was wondering if you could still find clocks or watches that were made to tell the time according to the French Revolutionary calendar, which among other things attempted to decimalise units of time (imagine if they tried that here! We raise enough of a beef if someone tries to tell our market-traders to stop selling potatoes by the hundredweight).
It wasn’t popular among French clockmongers, as it completely jiggered their export trade.
Anyway, yes, there are plenty such dials extant. Here’s one.
A watch from the 18th century that looks like a watch from a parallel universe.
