It needs power to start. My watch came-powerless-I attempted to adjust and set, nothing works w/o power. I called citizen and e-mailed several times, I was given case numbers, never got a response. I took to a jeweler, he said it needs power. Put it in light/sunlight, it started working. When I got a little juice, I adjusted and set, all good now! Just remember, it has to have some power.
Greatest watch ever... classy looking, indestructible, and uses the sun... perfect
I have owned this watch seven months. Works perfectly and whats nice never have to set time or concern about battery.
