Citizen's Eco-Drive technology was the reason for my purchase. Axiom is also beautifully designed like a bracelet, and I love it. What I did not realize, besides these obvious great factors, was an amazing and generous service of one-time wrist band adjustment for free. I have had coach watches, but I had to look for a jewelry store to have it shortened, of course with a fee out of my pocket. I do not see why I would buy a watch other than Citizen's after seeing the great value it provides its customers.
