Citizen Eco-Drive, Solar powered movement, AW1410-08E, ” Chandler” model. The watch is rather large at 44 mm case diameter, Approx. 12 mm case thickness, 22 mm lug width. This is a nice watch that has only been worn twice. I’m selling it because I think it’s too large for my wrist and it’s quartz. My only gripe with this watch is a slight misalignment of the seconds hand. This isn’t a defect and, in fact, is somewhat common for quartz watches, even at higher price points. It’s really a matter of microns, but I’m a watch nerd now and have gone totally with 28,800 BPH mechanical watches for the smooth sweep of the seconds hand. So, if you’re a watch nerd like me, don’t buy this watch. However, if you want a good watch, that keeps good time, at a good price, then I think this watch would serve your needs.
