Rich in features and solidly built, the hand assembled Citizen Calibre 2100 has the look and feel of a more expensive watch. The chronograph second hand moves in 1/5 second increments instead of ticking one second at a time giving it the sweep motion associated with an automatic movement. Model AV0031-59A also features Eco-Drive technology (solar powered, never change a battery), a power reserve meter, alarm, date display, non-reflective mineral crystal, solid stainless steel case and bracelet, screw-back case and screw-down crown. The chronograph measures up to 12 hours and has an instantaneous zero reset button.
