Citizen Ecodrive Watches

Citizen Eco-Drive

The first Citizen Eco-Drive watches, which are light powered watches, were sold in 1995. There is an amorphous silicon solar cell behind the dial that charges a titanium lithium-ion secondary battery. This high tech watch will never need a battery change, and comes in many cool and attractive styles for men and women.

For men the Solar-Tech 180 Titanium is a rugged looking sport watch that is water resistant up to 200 metres. It is a quartz watch with a one-way rotation elapsed-bezel, date window and a screwed down crown. It is a very light and durable watch, being mostly titanium and has a good safety clasp.

It is all stainless steel, water resistant up to 200 metres and also never needs a battery. With the black dial and red highlights, this is the watch of a lifetime.

The Largo has a dressier look, all stainless steel and black dial, with the same water resistant and battery features as all Citizen Eco-Drive watches. It has 12/24 hour time and 1 second chronograph measuring up to 60 minutes.

The Miramar Chronograph is an elegant two toned stainless steel and rose gold watch with 28 diamonds around the mother of pearl dial. This watch could go anywhere as it has sports features as well as elegant design features.

The Stiletto is another beautiful watch, all stainless steel gold tone with a simple rectangular white dial.

The Normandie, for ladies, is a dress watch with Swarovski crystals all along the face and around the band. It comes with a rectangular or oval face in stainless steel and with black ion plating. These watches never need batteries and are also water resistant.

Citizen Eco-Drive watches are truly the leaders in environmentally friendly timepieces. They are very strong, even the delicate ladies styles, and will last for decades, never needing a battery. The sports watches and chronographs can stand any challenge and never let you down. All of these features combined with some of the best watch styling in the business makes this a watch worth owning.
