The Seiko Kinetic approach is probably what Nikon would impliment.
Olympus would have used the same sort of technology that is in a Citizen
Eco-Drive watch.
Mine has a Titanium case and strap, is water resistant to 100m, is solar
powered and has a Titanium/Lithium ion rechargeable battery.
The whole watch face is a high efficiency solar cell. From dead-flat, the
battery is fully charged in 3.5 hours of exposure to direct sunlight.
Fully charged, it can run for 6 months in complete darkness.
Makes the technology in a Seiko Kinetic look like something from Victorian
England. ;-)
10min of exposure to the light from an overcast day is sufficient to run
it for a day. There seems to be no real need to purposefully 'charge' it.
It gets plenty of light by just being worn.
