Citizen E110M

The Citizen E110M is a solar quartz movement with a capacitor that functions as a rechargeable secondary battery, manufactured in Japan. It maintains accuracy within ±15 seconds per month and features a date complication, with approximately six months of power reserve from a full charge. A distinctive characteristic is the low-energy warning system, where the second hand jumps every two seconds to signal the capacitor is losing power, though the watch continues to keep time for roughly one week before stopping.
