Key-wind/Key-set Movements
The very first pocket watches up until the third quarter of the 19th century had key-wind and key-set movements.  A watch key was necessary to wind the watch and to set the time.  This was usually done by opening the case back and putting the key over the winding-arbor (which was set over the watch's winding-wheel, to wind the mainspring) or by putting the key onto the setting-arbor, which was connected with the minute-wheel and turned the hands.  Some watches of this period had the setting-arbor at the front of the watch, so that removing the crystal and bezel was necessary to set the time. 

This watch includes a reproduction of the correct size key, it is not the original.

Verge Fusee Escapement
Used in antique spring-powered mechanical watches and clocks, a fusee is a cone-shaped pulley with a helical groove around it, wound with a cord or chain which is attached to the mainspring barrel. Fusees were used from the 15th century to the early 20th century to improve timekeeping by equalizing the uneven pull of the mainspring as it ran down. The mainspring is coiled around a stationary axle (arbor), inside a cylindrical box, the barrel. The force of the spring turns the barrel.
