Citizen E101M
Description
An unusual quartz movement is the Citizen E101M, also known as “Eco-Drive”, which is solar-powered.
quartz movement w/o solar module
Without the solar module, it would be a quartz movement that’s neither particularly small nor very large, displaying hours, minutes, seconds, day, and day of the week.
Power and storage of the solar energy is provided by a Panasonic MT 621 lithium coin cell battery Panasonic MT 621, with a voltage of 1.5V and a capacity of 2.5 mAh.
