The invention of this portable sundial is attributed to monks in the forests of Prussia in 1721.
How it works: Turn the sliding ring until the hole shows the current month. Hang the clock side with the small hole in the direction of the sun. A sharp point of light appears on the time scale inside the ring and shows the WOZ (true local time): the morning hours on the left, the afternoon hours on the right.
Very beautiful as a necklace - a ribbon is included.
Instructions for use are included.
Diameter: 26 mm
Material: brass outside; 925 sterling silver inside
