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. Bridge Style Layout
The metal bar which bears the pivot of wheel and is supported at both ends.  The bridge style watch has two or three fingers to hold the wheels in place and together are called a bridge.  The term bridge (horologically) is one that is anchored at both ends.
Lever Escapement
An escapement is a device in mechanical watches and clocks that transfers energy to the timekeeping element (the "impulse action") and allows the number of its oscillations to be counted (the "locking action"). The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper oscillating. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece's gear train. Each swing of the pendulum or balance wheel releases a tooth of the escapement's escape wheel gear, allowing the clock's gear train to advance or "escape" by a fixed amount. This regular periodic advancement moves the clock's hands forward at a steady rate. At the same time the tooth gives the timekeeping element a push, before another tooth catches on the escapement's pallet, returning the escapement to its "locked" state. The sudden stopping of the escapement's tooth is what generates the characteristic "ticking" sound heard in operating mechanical clocks and watches.
