In principle, yes. But you should of course avoid them wherever possible. Or tighten the watchstrap as much as possible - this alone is a good way of reducing the effects of impacts. It also helps to compensate for fluctuations in temperature.

A mechanical wristwatch is a precision instrument. Tolerances at the manufacturing stage are in the hundredths and thousandths of millimeters. Extreme, repeated shocks and impacts can have a negative influence on the rate of a watch movement.
