Citizen Eco-Drive Super Titanium watch, titanium, AW1900-50A
Silver-colored Citizen Eco-Drive watch with a lightweight titanium case, red seconds hand and date display
The red seconds hand brightens the otherwise understated silver-colored sunray dial of this Citizen watch. The round titanium case is 40 mm wide and 9 mm thick, and the titanium bracelet continues the same gray tones. The date display is at three o'clock, and the luminous hands and hour markers make the time easier to read in dim light. The dial is protected by mineral crystal.
The watch is powered by light, so you never need to replace a battery. When fully charged, the power reserve is about 240 days. According to Citizen, Super Titanium is about 40% lighter than stainless steel and up to five times harder, and the whole watch weighs 78 g. Water resistance of 50 m / 5 atm withstands sweat, splashes and rain, but the watch is not suitable for snorkeling or diving. In 2026, Citizen is celebrating the 50th anniversary of Eco-Drive.
