Citizen Eco-Drive Promaster Sky watch, steel, CA4664-60X
Copper-toned Citizen Eco-Drive Promaster Sky Steel Chronograph Watch with Date Display and Sapphire Crystal
A copper-toned dial and three dark gray subdials set this Promaster Sky chronograph apart from an ordinary steel watch. The chronograph measures up to 60 minutes, and the date display is between four and five o'clock. The bezel has a scale that shows liters and gallons, among other things. Luminous hands and indexes help you read the time in low light. The stainless steel case is 40 mm wide and 13 mm thick, and it is one of the smallest models in the series. The dial is protected by a sapphire crystal with an anti-reflective coating.
The Eco-Drive movement runs on light, so you never need to replace the battery. When fully charged, the power reserve is 9 months. Water resistance of 200 m / 20 atm is enough for swimming, water sports and snorkeling, but the watch is not suitable for scuba diving. The 50th anniversary of Citizen Eco-Drive is celebrated in 2026.
