I ended up returning this watch because the face was smaller than expected.
Had to take watch to jewelry store that handles watches as there was a conflicting issue. It had a small strip talking about a button battery and that it was run by light. The instructions were vague. But once I got my watch back I am very pleased with it.
Purchased a Skyhawk U830 in blue for myself. Love it so much, I purchased a Skyhawk U830 in black for my son's birthday. Can't wait to present it to him.
Awesome watch! I was a little hesitant to get it based on some people's concerns with difficulty in setting it. However, YouTube videos and the online user guide showed how to easily set the time by changing modes. Only things about the watch I would change is to make the metal components (i.e., the casing, the bracelet) a darker, true black. Also, the buttons are slightly mushy, and I prefer a crisper feel. But that's getting overly picky, and the watch looks, feels, and is awesome as is. The features of dual time zones, UTC clock, timer/stopwatch, alarms, calendar, etc. are awesome. Incredible amount of features to pack into this guy, and I've gotten lots of compliments about it. If you're on the fence on this watch, I recommend you go for it!
