Abstract

PURPOSE:To know time accurately by providing projections for hours and minutes, and by checking whether those projections are pressed with a finger with some resistance or in a completely free state. CONSTITUTION:In a watch, leaf springs 5 each semifixing an hour display projection 1 are arranged annularly, and at the outside, leaf springs for minute display projections 2 are arranged similarly, Then, a ring wheel holding the leaf springs for minute display rotates by a prescribed angle for every five minutes, and a ring wheel under those projections 2 does not correspond to the leaf springs, so that the projections move up and down freely. For hour display 1, a ring wheel 6 where the leaf springs are fixed rotates by a prescribed angle for every hour, and a ring wheel 6 under the projections does not correspond to the leaf springs, so that the projections move up and down freely. Consequently, the projections for hours and those for minutes are touched with a finger to know time accurately.
