Watch including a movement that incorporates a tourbillon mechanism having a single cage (13, 18, 22) holding the balance (15), this cage (13, 18, 22) rotating about an axis (X--X) forming an angle with the plane of the watch movement. The axis of rotation of the balance (15) forms an angle essentially perpendicular with the axis of rotation (X--X) of the cage (13, 18, 22).

Watch movement comprising a housing (26, 28, 30, 32, 34) and a gear train, formed from a series of spindles (36, 38, 40, 42), pivotably mounted on the housing, of which a first of said spindles (42) is provided with a shank (42a), for fixing a first hand (16) and a second of said spindles (50) is provided with a cylinder (50b), arranged co-axially to said shank, for fixing a second hand (20). According to the invention, the second spindle (50) is rotationally mounted on said housing (34) by mean...

A watch apparatus includes a wristwatch that includes a watch housing with a face, a back side and a peripheral edge. A wristband is attached to the peripheral edge. A bezel is rotatably mounted to the watch housing and extends around the face. A motor is mounted on the peripheral wall of the watch housing. A gear assembly is mechanically coupled to the motor. The motor is adapted for rotating the gear assembly. The gear assembly is in communication with the bezel so that the bezel rotates when ...

A watch case comprising a rotary bezel, first and second angular positioning markings, one set secured to the bezel and the other set to the case middle and elastic means in the form of a closed-loop spring tending to place the positioning markings into engagement with one another. These markings are distributed with numbers of spacings one of which is a multiple of the other and the outlines of which extend in a plane parallel to that of the bezel. Guide means are engaged with the markings havi...

A personal data assistant ("PDA") watch uses a "character wheel," or a "data dial," to enter information, or characters, into the PDA watch. Such a dial makes the entering of data much quicker by taking advantage of the flexibility of the human wrist. A dial containing the character set disbursed around its circumference can be turned to indicate which character the user wishes to enter. The selection of a particular symbol/character can then be made by depressing the dial or some other input bu...

An electronic watch diversifies the mode of display for numeric information and the like to presents the information using the natural ambient light or a back light. The electronic watch may includes a polarizer for transmitting a linearly polarized light polarized in one direction while absorbing the remaining polarized light, a liquid crystal element that selects a state in which the polarization of a polarized light ray is changed through transmission and a state in which the polarization of ...
