Abstract

Abstract An electronic watch, which includes a time base, a logic circuit and an electronic display, comprises a data input device including at least one manual control member for transferring data, e.g. a numerical value or a numerically coded instruction, into the logic circuit by means of a logic transfer circuit. For example, any of 60 different data of any kind may be introduced into the logic circuit by means of a single push button. A number between 0 and 59 is attributed to each of these data. Any of these data is introduced by pushing the button where the corresponding number is displayed by the seconds display. Alternatively, a number indicated on a separate display by means of a separate counter can be selectively transferred into any part of the time counter to thereby set the time. The number indicated can be transferred into any digit of a register part of an auxiliary calculator included in the logic circuits to thereby introduce the number to be processed. Alternatively, an indication of a first unit of time (e.g. seconds) can be transferred to replace and thereby correct an indication of a second unit of time (e.g. hours), a supplementary impulse generator selectively accelerating the sequential indication of seconds.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 99 words
In an electronic watch having a time base, a logic circuit, an input of which is coupled to an output of said time base, and an electronic display means coupled to the output of said logic circuit, the improvement comprising: data input means coupled between the output of said logic circuit and a further input thereof for selectively transferring signals from the output of said logic circuit to said further input; and manual control means coupled to said data input means for selecting the data to be transferred from said output of said logic circuit to said further input.
Claim 2
Dependent Claim 99 words
In an electronic watch having a time base, a logic circuit, an input of which is coupled to an output of said time base, and an electronic display means coupled to the output of said logic circuit, the improvement comprising: data input means coupled between the output of said logic circuit and a further input thereof for selectively transferring signals from the output of said logic circuit to said further input; and manual control means coupled to said data input means for selecting the data to be transferred from said output of said logic circuit to said further input.
Claim 3
Dependent Claim 46 words
An electronic watch according to claim 1, wherein said logic circuit includes first means for generating a signal corresponding to units of time to be displayed on said display means, the input of said data input means being coupled to the output of said first means.
Claim 4
Dependent Claim 40 words
A watch according to claim 1, in which actuation of said manual control means causes transfer of data displayed by said display means to a circuit to cause a shift in said circuit, said shift corresponding to said displayed data.
