An astrolabe was used to measure the angle between the zenith (point directly overhead) and a celestial body such as the sun during the day or the north star at night. Christopher Columbus would have used an astrolabe to help him navigate the ocean to the New World. This Astrolabe Watch incorporates this early astronomical insturment.
Happy Columbus Day!
The sundial was the original pocket watch, the earliest method of telling time. Like mariners for centuries, you can tell time by the sun with this Maritime Pocket Sundial. Just align the compass to north and the string shadow will fall on the hours.
Jewish people throughout the world will give the sun a birthday blessing this morning. According to Judaism, the sun returns every 28 years to its precise position in the sky as when it was created, 5,769 years ago.
Happy birthday, Sun!
