If you are wearing a quartz battery powered watch the answer is no.

If you are an owner of an automatic or self-winding watch note that the watch movement provides about 30 - 40 hours of power or functionality when fully charged. The normal movement of your wrist while wearing your watch should keep the movement “charged”. However if you do put down your watch for a couple of days it maybe necessary to wind the movement and give the watch a gentle shake to get it going before putting it back on your wrist.

Over time the lubricants inside your automatic watch may dry and deteriorate. It is therefore advised that for prolonged use you should take your watch in for inspection and servicing every couple of years to ensure years of optimal functionality.
