Citizen Eco Drive Sport
An officer at a department in Georgia. The watch was a birthday gift. A month later he was assigned to his department's Crime Suppression Unit. Getting ready to head into work, he took a moment to admire it and how sturdy it has been thus far. Sturdy enough that it has now replaced his Garmin. A Citizen Eco Drive Sport.

Citizen Eco-Drive
Eco-Drive is Citizen's answer to the most boring failure a watch can have, the dead battery. Light, any light, passes through the dial to an amorphous silicon solar cell hidden underneath, which feeds a rechargeable lithium-ion cell. By 1995 Citizen had pushed the reserve to six months of running time in total darkness on a full charge, and the Eco-Drive line launched in the United States in 1996 with the calibre 7878, the first design that hid the solar tech well enough to let the dial just look like a dial.
The practical result is a quartz watch that never needs a battery swap. Citizen estimates its light-powered watches have kept over 100 million disposable batteries out of landfills since it began building solar movements in 1976.
For a Crime Suppression Unit officer, that math is simple. Wear it, forget it, let the daylight through the windshield do the maintenance.
