Ive got one of those wristwatches that is wound by movement. The first page of the instruction leaflet says, This watch is wound by normal wrist movement. Three minutes of normal wrist movement will wind the watch for about 8 hours.

That means that an episode of Baywatch should wind it up for, lets say about a week. 🙂

(For those in countries which dont receive Baywatch, it is a US American TV series in which everything from plot to production values is secondary to the breast size of the female characters.)
