Offered is an extremely rare, unused Rüter-Uhr - pocket sundial from old stock from the earliest post-war period 1946, of which only 8000 were produced and which is considered a classic in the sundial sector, an absolutely original piece in good condition

Included is the rare luxury case as original packaging (normally the Rüter sundial was only sold in a cardboard box)

Considering that this most famous of all sundials was produced only 8000 times almost 70 years ago, one can appreciate how rare it is to find a complete full set piece anywhere

The function of the most famous of all sundials was patented by the inventor Dr. Rudolf Rüter

As a rarity and piece of watchmaking history, it is exhibited in many collections and museums, as well as in the Berlin Planetarium.

The special trick of the Rüter clock is/was that it has a compass and could thus always be aligned north and displays precise time in all places in Europe

To read the time, the pocket sundial is held horizontally in the sun, then the brass button on the underside is pressed, which causes the dial to align in a north-south direction. After the dial has come to rest, the time can be read from the shadow of the gnomon.

Diameter approx. 5.3 cm

The Rüter clock is in excellent condition, never used, dial flawlessly preserved
