Citizen Super Titanium Radio Controlled AT8398-53X watch

Citizen Super Titanium Watch with Green Dial, Radio Control, Chronograph and World Time

A green, textured dial and a tachymeter bezel in the same shade set this Citizen chronograph watch apart. The titanium case is 40.5 mm wide and 10.4 mm thick, and the titanium bracelet is 21 mm wide between the lugs. The case and bracelet are made of Citizen's Super Titanium, which the manufacturer describes as lightweight and scratch-resistant. A sapphire crystal protects the dial, and the hands and hour markers are luminous.

The Eco-Drive movement is charged by light, so the battery never needs to be replaced. The watch is radio-controlled: it receives the signal from a local atomic clock, and according to Citizen the deviation is one second in 100,000 years. In addition to the chronograph, the watch has a stopwatch, world time for 26 cities, a perpetual calendar, a day and date display and a power reserve indicator, and it is anti-magnetic. World time is handy when traveling. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving.
