Ive had this watch for about a month and it has replaced a G-shock as my go-to daily watch. I wanted to try the solar power part of the watch, and so far its working fine. For the month its about 10 seconds slow, inconsequential to me. The second hand hits all the markers, and I love the blue face and fabric band. While I have bigger watches, 43mm seems to be the perfect size for my 7-inch wrist. If it keeps up the good work, I would give it a strong recommend.
