I bought this for my husband for Christmas and originally had a couple issues getting one that worked right, which is why I docked off a star. The first one we got looked used, it had smudges and scratches on the back side of the watch. The second one didn't work at all. We thought about just going to see if a new battery would fix it, but after a pretty steep price we figured we'd just send it in for anot her replacement just in case it was faulty. We we're losing faith that it would work out but thankfully the third watch was flawless. It works perfect and there wasn't a scratch or mark on it. It's the perfect size for his wrist and looks casual but fancy at the same time. He loves the aviation details and is finally happy with his present!
