The Santos Dumont as we know it today is a modern interpretation of the original early 1900's model with a few modern touches but in general it is unmistakable. This watch was not worn much, it is still very clean overall with surface marks on its bezel. The band and buckle are original. Box and papers were lost in a move by the original owner.
