Abstract
A wristwatch has a rigid watchcase and opposed pairs of lugs for mounting a wristband. The watchcase houses a battery-powered quartz watch movement and includes a number of battery compartments outside of the watch movement for batteries to power the watch movement. Each battery compartment has a door that enables changing the battery in the compartment without exposing the watch movement to the outside environment. The lugs are integrally attached to the doors and provide convenient handles for opening and closing the doors.
Claims20
A wristwatch comprising:
- a rigid watchcase extending between a pair of opposite ends, the watchcase defining an interior case compartment, a watch movement within the case compartment, and means for displaying the time operatively connected to the watch movement;
- the watchcase defining a first pair of battery compartments in the case compartment adjacent one end of the watchcase and a second pair of battery compartments in the case compartment adjacent the other end of the watchcase, each battery compartment being configured to retain a battery for powering the watch movement;
- electrical connections in the case compartment extending from each battery compartment to the watch movement to transmit electrical power from a battery in the battery compartment to the watch movement when a battery is in the battery compartment;
- a pair of spaced apart lugs extending from each end of the watchcase, each pair of lugs configured to mount an end of a watchband to the watchcase;
- and
- each lug movably mounted on the exterior of the watchcase adjacent a respective battery compartment, the lug forming a battery compartment door and movable between a first position wherein the respective battery compartment is open for insertion or removal of a battery from the battery compartment and a second position wherein the respective battery compartment is closed to retain the battery in the battery compartment.

A wristwatch comprising:
- a rigid watchcase comprising an exterior portion defining an interior case compartment, a battery-powered watch movement within the case compartment, and means for indicating the time operatively connected to the watch movement;
- the watchcase defining a watch movement compartment and at least two battery compartments in the case compartment, each battery compartment configured to retain at least one battery in the battery compartment, the watch movement in the watch movement compartment and outside of the battery compartments;
- and
- electrical connections in the watchcase and extending from each battery compartment to the watch movement to transmit electrical power from a battery in the battery compartment to the watch movement when a battery is in the battery compartment, the electrical connections comprising means for selectively switching between each of the battery compartments so that only the battery or batteries in the selected battery compartment are electrically connected to the watch movement during normal operation of the wristwatch, the means for switching comprising a mechanical switch and a crown extending out of the watchcase to mechanically operate the switch.

A wristwatch having selectable and redundant power sources, the wristwatch comprising:
- a rigid watchcase comprising an exterior portion defining an interior and a battery-powered watch movement within the interior, the watch movement comprising means for indicating the time;
- the watchcase defining at least two battery compartments in the interior of the watchcase, each battery compartment configured to retain a power source independently capable of operating the watch movement to indicate the time, each power source comprising at least one battery;
- electrical connections in the watchcase extending from each battery compartment to the watch movement to transmit electrical power from each power source to the watch movement;
- the electrical connections comprising a switch mechanism operatively connected between the power sources and the watch movement to selectively electrically connect a power source to the watch movement and electrically disconnect all the other power sources from the watch movement so that only one power source is electrically connected to the watch movement during normal operation of the watch movement;
- and
- the switch mechanism being actuatable to disconnect the connected power source from the watch movement and connect one of the one or more disconnected power sources to the watch movement whereby power sources may be successively connected to the watch movement to extend the normal operating life of the wristwatch as compared to a conventional wristwatch having a single power source.

A battery-powered wristwatch comprising:
- a rigid watchcase defining an interior compartment, a battery-powered watch movement within the watchcase compartment, the watch movement comprising means for indicating the time, and electrical connections in the watchcase to transmit electrical power from a battery to the watch movement;
- the watchcase comprising a battery opening, a door for opening and closing the battery opening, and a door hinge mounting the door to the watchcase, the door hinge defining a pivot axis;
- and
- the battery opening communicating the ambient environment outside the watchcase with the interior compartment for inserting or removing a battery from the watchcase, the door pivotable about the pivot axis between opened and closed positions to open and close the battery opening, wherein the door is mounted to the watchcase by the door hinge in all door positions.
