Eco-Drive Frequently Asked Questions
How can you tell if the Eco-Drive watch is getting enough light? In normal use, the watch displays the time and the sweep-second hand moves in one second intervals. A very important feature of Eco-Drive is the Low Charge Warning Mode which as a result of low battery voltage, causes the second hand to jump two seconds at a time (while still keeping correct time).

How long will an Eco-Drive watch run after it is fully charged?
If your watch is put away where no light is available to it while in a fully charged state, depending on the model, it will run for from 45 days to 5 years.

How can the Eco-Drive watch be recharged?
Besides sunlight, it can be safely charged by exposing it to a fluorescent desk lamp, with the dial (face) up and within about 8 inches or an incandescent lamp (regular light bulb) no closer than 20 inches. Never use a halogen lamp since the heat generated by it can cause damage to your watch. The most efficient and the quickest is in direct bright sunlight (not windowsill) and never on the dashboard of a car.

Warranty
It's backed by Citizen's 5-year warranty (from original date of purchase).

About Citizen
One of the world's largest watch makers, the Citizen Watch Company was founded in 1924 in Japan from its beginnings as the Shokosha Watch Research Institute. The first watch released by the company was named "CITIZEN" and its name was selected so that it would be "close to the hearts of people everywhere." Today, Citizen is recognized as a worldwide leader in advanced timepiece technology, from the world's slimmest LCD watch to the first voice recognition watch to the world's first professional dive watch with an electronic depth sensor. Citizen was also the first to sell watches made with titanium in the world, which is not only light and durable but also non-allergenic (as stainless steel can be to some wearers). Most recently, Citizen has released watches powered by its Eco-Drive, which runs continuously in any kind of natural light or artificial light for a lifetime of use without changing a battery.

Rating : - The beginning of this watch started off a little shaky!
I bought this watch for myself as a treat for becoming certified as a diver.

It has all the great features for diving of a dive computer without the bulkiness of one. The only thing it DOESN'T record is AIR COMSUMPTION, so I had to buy a small pressure gauge. It did avoid me having to buy a large wrist computer and also a separate dive watch!

Two separate times I was deep diving (about 80 feet) and it malfunctioned and just locked up for no reason. So the worst thing about it was my dives WEREN'T recorded in the watch. As it stores several hundred dives normally!

Upon returning to the states, luckily for me, Citizen HQ is about 15 minutes drive from my house! They replaced it with a new one for free, since they could not get it to work again.

NOW IT WORKS FINE!

I wear it DAILY as a regular watch! It withstands BANGING and you can shower with it, and it 'knows' you aren't diving and doesn't record!

I GET COMPLIMENTS EVERY TIME I WEAR IT. As it looks very unique from other watches!

It has tons for cool features, and you can upload the dive logs to your computer, as well as to your friend if they have the same watch!

I only have to charge it on the dock ONCE A MONTH!

OVERALL. Apart from a rocky beginning, I LOVE THIS WATCH WITH ALL MY HEART, and I never leave home without it. Except on some fancy dress up events, but then I take a SMALLER DIAMOND CITIZEN WATCH! hahaha
