This looks better in person. I had purchased it for my husband as he was looking for a dress watch. This is perfect! The watch is beautiful and the packaging is beautifully done. I'm beyond happy with this product and plan to buy another one in a different color for my son. Definitely go for it and buy it. It's worth it.
