Looks exactly as pictured
Color: Gold
Bought this as a graduation gift for a sons friend who admired a similar one on vacation with us. He really liked it and it is a nice entry level dress watch for those who like to collect them. It was easy to adjust the band with a personal watch kit and was heavier than I expected.
