I just discovered this speedometer and this chronograph made by Rolex. (Click on the image to see where I got it from.) Do you notice anything unusual? (Hint: The text between the 7 and the 8 on the speedometer reads “MACH 1.”)
Rolex is the official timing partner of the BLOODHOUND project. The BLOODHOUND SSC (supersonic car) was created to break the land speed record by going at least 1,000 miles per hour. More information can be found here and here. The speedometer’s white hand shows the current speed, and its green memory hand shows the fastest speed reached (and can be reset). The chronograph is a clock (the subsidiary dial displays the time in hours and minutes) and a stopwatch (the main dial measures minutes and seconds).
