Offered is an extremely rare Rüter watch - a pocket sundial with a super rare blue original packaging from the earliest post-war period 1946, of which only 8000 pieces were manufactured and which is considered the classic in the sundial sector, an absolutely original piece

Included are the original packaging and the original operating instructions from the manufacturer (see photos)

When you consider that this most famous of all sundials was only manufactured 8000 times almost 70 years ago, you can appreciate how rare it is to find a complete piece in a full set anywhere

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

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

The special feature of the Rüter watch is/was that it has a compass and could therefore always be aligned to the north and displays the precise time in all places in Europe

To read the time, the pocket sundial is held horizontally in the sun, then the brass knob on the underside is pressed, which aligns the dial in a north-south direction. After the dial has come to rest, the time can be read from the shadow cast by the hand.

Diameter approx. 5.3 cm

The Rüter watch is well preserved, the dial is flawlessly preserved, otherwise normal, visible signs of age or use as shown in the photos, the "glass" has clear signs of use in the form of scratches, but the dial is easy to read, original packaging good without tears, only abrasions on the edges
