Citizen Watch: Eco-Drive Titanium Radio-Controlled Black AT8390-55E

Radio-controlled Citizen: black dial, titanium and world time

The radio-controlled Citizen Eco-Drive with a black dial (AT8390-55E) combines a chronograph and world time in a 40.5 mm case. The black dial highlights the light-colored indices and gives the watch a more understated look.

The Super Titanium™ case and bracelet weigh a combined 89 g. At 10.42 mm thick, the watch maintains a compact profile despite its sub-dials. A sapphire crystal protects the dial.

The Citizen H804 movement draws its power from light thanks to Eco-Drive. Radio synchronization sets the watch when it receives a compatible signal, while the world time display for 26 cities makes switching between time zones easy.

The perpetual calendar displays the day and date. The chronograph measures up to 60 minutes to 1/20th of a second, and the power reserve indicator allows you to check the charge at a glance.
