Abstract
A display mechanism of a watch including at least one indicator member and a drive member assembly. The indicator member is mounted to rotate about a first axis of rotation and is configured to indicate a time. The indicator member also has a second axis of rotation extending along the indicator member and a rotary element mounted to rotate about the second axis of rotation. The drive assembly includes a first drive member and a second drive member such that the first drive member drives the rotary element when it is moving about the first axis of rotation.
Claims7
A display mechanism for a watch, said display mechanism comprising at least:
- at least one indicator member being mounted to rotate about a first axis of rotation via a first part, and being configured to move relative to a dial so as to indicate a first piece of information;
- said at least one indicator member being mounted to rotate about a second axis of rotation intersecting said first axis of rotation and extending longitudinally along said at least one indicator member and comprising at least one rotary element mounted to rotate about said second axis of rotation via a second part so as to indicate at least one second piece of information;
- at least one drive member assembly comprising at least one first drive member and at least one second drive member, said at least one second drive member being arranged on or in said at least one rotary element at a first end of the rotary element, and being driven by said at least one first drive member;
- said at least one first drive member being configured to cooperate and directly engage with said at least one second drive member in such a way as to drive said at least one rotary element in a rotational movement via said at least one second drive member,
- when said at least one indicator member is rotatable about said first axis of rotation and/or when said at least one drive member is rotatable about said first axis of rotation,
- wherein said at least one indicator member is a second hand, a minute hand or an hour hand, and
- wherein said at least one drive member assembly comprises a universal joint and at least one third drive member, said at least one third drive member being arranged at a second end of the rotary element opposite to the first end.
