Received this watch today from my favorite store JOMASHOP where I buy all of my watches, other than EBAY. JOMASHOP had the best price for this watch. I have been following CITIZEN for awhile now. I am starting to like their watches, the looks and especially some of their features. This watch is an ECO-DRIVE which means that this watch is ran by light, from any natural or artificial light. Energy is stored in a rechargeable solar cell. I really like the simple but elegant silver face. The watchband is made out of Polyurtehane. The case size is 45mm. I am going to make this my everyday watch I wear after work. I have other watches that I wear when at work. This will be my run around watch. KEEP ON TICKING!
