This stainless steel Citizen Promaster Eco-Drive watch contains some sophisticated technology. The black dial shows both the analogue and digital displays. The analogue display shows the time, 24 hour and UTC time. The digital display shows the time, city name, daylight saving times, calendar, three alarms, the chronograph function, timer and zone settings. As well as all that technology, the watch is 100m water resistant and is an Eco-Drive model ensuring that it charges when exposed to light.
