The Men's Citizen Eco-Drive Caliber 2100 Chronograph. This citizen 2100 is in very good condition as you can see by the pictures. All functions on my watch work as new, including the alarm and chronograph. The battery/solar cell was just professionally replaced with a correct factory Panasonic CTL 920 and the O-rings lightly greased with silicone. With age these cells start to go bad and with these 2100’s approaching 15 years old, they need to be replaced or they will not hold a charge for long. The glass looks great as well as the rest of the watch. The watch will ship with enough links to fit a large 7 1/2 wrist. The sale includes the watch only. Will ship USPS the next day business day after payments received. Thanks.
