Forsining Red Leather WristwatchA gorgeous racing inspired design. One look at this watch and you know it has motorsports in its DNA, from the dial to the leather band to the transparent back case. Automatic Mechanical Winding Movement. A very gracious and smooth German mechanical automatic winding hand movement. It is a very unique watch in that it charges itself (no batteries needed) as you wear it using the crown winding & your natural arm movement! Modern Transparent Swiss
