In an instrument for indicating time, indicating means which includes plurality of generally parallel discs arranged in spaced apart relationship lengthwise along an upright standard. The discs are fabricated of translucent material for transmitting light rays therethrough from the center of the discs, at the standard, to the outer marginal edges of the discs which define 360 DEG time indicating reference strips whereby the time indication of the discs may be seen from any point of observation laterally of the instrument. The discs are arranged in four relatively spaced clusters of three discs each in any number of twelve discs along the standard whereby each cluster may represent a three hour increment of time and/or each of the four clusters facilitate representing a one-quarter hour increment of time.
