Abstract (en)
[origin: US5453960A] This watch (1) includes a case (2), a glass (3) and at least one manual control device (22), which comprises a capacitive sensor (20) with a first electrode (5) arranged on the internal face (6) of the glass (3). The selective positioning of a finger (10) of a wearer of the watch (1) on the external face of the glass (3) enables a first capacity (Cd) to be formed between the first electrode (5) and earth (11) constituted by the case (2). A parasitic capacity (Cp) is present between the first electrode and the case. The manual control device (22) also includes a voltage-frequency converter (22) whose oscillation frequency is determined by the first capacity (Cd), when the latter is formed by the presence of the finger, in combination with the parasitic capacity (Cp),
