RA Sundial Ring

The singularity of gathering in a personal ornamental item such as a ring, with the so-called gnomonics sundial science, turns this piece into a singular object, unique in its design, eye-catching and easy to wear that attracts the observer's looks and curiosity and also offering a special way to measure time.

How it works: Expose the ring to the sun and southwards moving it until we see a ray of light on the timebase. The lighted number will indicate the solar time.

* The ring is adaptable.

Presentation: In an individual box with operating instructions in Spanish, English, French and German.
