I'm selling my Marathon CSAR Chronograph Pilots watch. Serial # 0872. The watch is in great condition and the time and day function perfectly. However the date does not move with the time and day, and the center bezel does not catch the threads to screw in. I have adjusted the price accordingly in order to send the watch to have it repaired. It will come with the watch pillow, case and box as seen in pictures. No international shipping and no returns.This description was pulled from Marathon's website.This chronograph has chronograph timing capabilities but can also be used as a Dive Watch. Movement is 7750 ETA Valjoux Automatic (Self Winding) 25 jewel minimum Swiss Made Movement.
