Universal Astronomical Ring
Beautiful little equinoctial ring sundial. Ideal to hang round your neck. This version can be used at any latitiude in either hemisphere. This dial did not arrive at its final form until William Oughtred published a description of it in 1652.
He introduced the bridge and the sliding Gnomon set to the current date – thereby making this dial truly universal and portable.The concentric rings fold flat to slip into a pocket but open up to give a fully-working astronomical ring
you can use as a hand-held sundial. Diameter 61 mm, 6 mm slim with nylon lanyard.

latitudes, a meridian ring showing the latitude scale, a moveable hour
ring and a central, grooved bar that is graduated for the months of the
year and a perforated cylinder, which moves over this. It will indicate

Ring Dial - Original
In the 15th century, sailors estimated their latitude by the height of the stars in the sky.
Looking for greater precision in the measurement of the height of the Sun, Pedro Nunes 1573
invented an instrument that became known as the nautical ring dial.
It's a ring whose centre is movable. When held vertically, a little hole lights the sun shine through onto the hours written on the inside.
It has a corrective device in the holding throne (hanger) and can be used for a series of parallel latitudes 20 30 40 50 60.
