According to the theory of relativity, from your own frame of reference (inside the spaceship), you would not notice any difference in the behavior of your watch. Time dilation affects how an observer in a different inertial frame (e.g., someone stationary relative to the spaceship's motion) would perceive the passage of time on the spaceship, not how you perceive time on the spaceship itself.
