This watch is part of the Citizen Eco Drive-line that synchronizes with atomic clocks (reference number AT9013-03H). The perpetual calendar has an analog world time that keeps time in 26 time zones, and the watch is powered by light. That means it never needs a battery change.
It is an extremely versatile watch, being water proofed to 200 meters, so you could actually go scuba diving with it. However, the rose gold case gives it more style than a divers watch, and it comes with a handsome brown leather strap with orange details. The case diameter is 43mm, and it has two pushers to operate the watch, in addition to the crown.
