Sinn 917 GR Rally Chronograph
Last month, German watchmaker, Sinn, introduced a new model, the 917 GR Rally Chronograph. The new Rally Chronograph features a countdown bezel that is controlled by the crown at 4 o'clock. This makes it possible to read off finish times with to-the second accuracy, with red numerals to call attention to the all-important, final 15-seconds.
