A voltage source supplies an adjustable voltage to the liquid crystal cell; adjustment of the voltage to change the transparency of the lens is effected by a photocell which senses ambient light, or by manual control, or both.

  • Timepiece with an eccentric display module
    Patent number: 4932010
    Abstract: A timepiece includes a clock movement whose axis coincides with the central axis of the case, and a module for displaying the time which is constituted by a unit which is independent of the movement and of the case and whose axis is spaced from the central axis of the case. The elements for coupling the display module to the case are arranged symmetrically about the central axis of the case so as to enable the display module to be arranged in various possible eccentric positions around the central axis of the case.
