If the chronograph in your Ottawa or Kingman watch is not zeroing correctly, before you consider returning the watch to us, please follow these instructions. It is most likely that your watch needs calibrating.
1. Pull the crown out fully.
2. Top dial (SEC 1/10): keep pressing the top button to adjust the top dial until it reaches zero.
3. Bottom dial (SEC): keep pressing the bottom button to adjust the bottom dial until it reaches 60..
4. Dial on the left (MIN): hold the bottom button until the MIN dial reaches 60
Following these instructions, you should be able to set your chronograph watch to the correct "zero point".
It is normal to "uncalibrate" your watch by pressing buttons when the winder is out, or after a battery change the watch often needs zeroing.
