No, wearing a wristwatch while running will not damage a mechanical movement. In fact, mechanical watches have been worn in stressful situations such as war and heavy labor for centuries. The only thing to be aware of is big repeatable shocks, which rarely occurs during a run.
Here are some tips for running with a mechanical watch:
- Choose a watch that is made for sports or has a shock-resistant case.
- Make sure the watch is properly sized so that it does not bounce around on your wrist.
- Avoid running on rough surfaces.
- If you do experience a shock, stop running and check the watch for damage.
With proper care, your mechanical watch can withstand the rigors of running.
