I don't think a new battery was put in the watch, as advertised. When I received it, many of the functions didn't work (such as backlight). I had the battery replaced (at my cost) and now those functions work. Watch looks nice. Compass and temperature are a bit finicky. Casio apparently makes changing the battery a bit frustrating. There are good disassembly videos on YouTube. Be careful about losing the small spring. Seller's price ultimately was not very competitive given the battery issue.
