Retroworks Sundial Ring Silver Finish (Size 12, Silver)

This ring is based on the original sundial ring Queen Eleanor gave to her husband, Henry II of England in about 1152. On a cloudless day, hold the ring upright aligning one of the 3 reference lines straight up. Rotate the sun dial until the hole is next to the current date (month of the year and beginning/middle/end of the month) A beam of light illuminates the time on an inside clock scale. Calibrate by using the reference line that works with your latitude - northern cities will use a different line than southern ones. The 3 reference lines allow Daylight Savings Time adjustments as well. Made from VERY durable stainless steel, acid etched markings.
