Abstract

A timepiece indicates the time by means of a single hand for minutes and a dial for hours both of which rotate, the dial being driven at a reduction in speed of 11:12 relative to the hand. As the minute hand rotates it moves one hours division relative to the dial and the time can be read by this relative position and the position of the minute hand relative to the watch casing.

Description

TIMEPIECE This invention relates to a timepiece that displays the time using a single hand and a dial.
The mechanism is substantially similar to an analogue mechanism which has an hour hand, a minute hand and a dial.
The essential difference in this new timepiece is that the gearing has been changed such that the pinion gear attached to the hour hand has been altered to drive the dial. The minute hand .is not changed and rotates at one revolution per hour. The gearing ratio, however, between the minute and hour gears has been changed from 12:1 to 12:11 such that the dial, rather than the hour hand, rotates at 11/12 the speed of the minute hand.
When the minute is pointing vertically upwards (at the O'clock position) it is coincident with a number thus implying that the time is exactly at the hour of this number. From this time the dial and hand rotate in the same direction, the dial lagging slightly behind the minute hand.
At any fraction of an hour the minute hand lies between adjacent numbers according to this fraction, such that a half past the hour the minute hand lies exactly half way between two numbers. After one hour has elapsed the hand is now coincident with the next number, registering the time as exactly on the hour.
The time therefore, can be told in minutes by the fraction of the hour elapsed from the O'clock position and in hours by the numbers adjacent to the tip of the minute hand.

Claims (3)

1. A timepiece that has one hand and one dial, both of which rotate.
2. A timepiece which illustrates the time according to the position of the hand and the dial relative to the watch casing.
3. A timepiece whose mechanism is substantially described in the accompanying drawing.
