These desktop timekeepers are gorgeous historical clock replicas. The first one is Astronomical Ring Dial, which is a 17th-century spherical sundial, the second one is Nocturlabe, which is based on a 16th-century artifact as you can see at the British Museum in London. These are unique Celestial Desktop Timekeepers that would add vintage touch to your desk. Each brass-dipped instrument provides an analog method of telling you about the current time. Through your position, the Astronomical Rings can cast a ray of light relation to the sun onto its timekeeping dials. When darkness falls, use Nocturlabe to determine the hour and minute by aligning with stars found in the Big Dipper and Little Dipper. They are beautiful reproductions that link you to technological past and experience the spirit of transoceanic exploration. [Buy It Here]
