Reply to comment by Der_Missionar in TIL the Passemant astronomical clock in Versailles has shown the correct date, time, moon phase, planetary alignment, etc (accounting for leap years ) from 1750 and can display through 9999. by kitkatbloo
Why does it lack crystals? My understanding is that the jewels in a clock/watch movement are placed in places where things spin. The jewels lower the friction between pieces and are hard so they don’t need frequent replacement.

When a ninja walk in with an itty bitty waste and a round thing in your face, your floor squeaks.
