  • Patent number: 9066563
    Abstract: A link assembly has a first link with an inner major surface and an opposite outer major surface, and a second link releasably engageable with the first link. The first link has two locking pins and two control pins, movable simultaneously with each other. When the first link engages the second link, the control pins move between locking and unlocked positions. When the control pins are in the locking positions, part of each locking pin is received within a respective hole of the second link to prevent disengagement of the first link from the second link. When the control pins are in the unlocked positions, the locking pins are clear of the holes to disengage the first link from the second link. Each control pin extends through a respective opening of the first link inner major surface. A spring biases the locking pins away from each other.

  • Patent number: 8974113
    Abstract: A wristwatch is disclosed as including a casing 12 having a first layer 14, a second layer 16 and a base member 18. The first and second layers are spaced apart from each other and are substantially transparent. The base member is spaced apart from the second layer and comprises a dial or a watch movement. At least one movable member 22 is movable relative to the first and second layers between a first position in which an end 24 of the movable member contacts the first layer, and a second position in which the end of the movable member is out of contact with the first layer. At least part of the movable member remains within a recess or a hole 20 of the second layer during movement of the movable member between the first and second positions, so that detachment of the movable member from the second layer is prevented.
