3 Minute Hourglass
Knotmeter - Egg Timer: By running out a line with equidistant knots, and measuring time with a sandglass, the speed of a sailing ship was defined and measured in "knots", for the amount of knots counted on the length of line run out during the sandglass timing. Our brass, handtooled sandtimer orginally counted approx. 30 seconds, which has been lengthened to 3 minutes. This makes it into a functional desk item to time phone calls. (Height 3.5") Available in brass, bronze or chrome. Please click here to see more hourglasses.
