Up/Down Wind Indicator
Some of the highest quality pocketwatches were equipped with a "wind-indicator" also called an "up-down indicator". The up-down indicator is a small dial indicating the amount of "power reserve" left in the wound mainspring. Most up-down indicators have a scale that points to zero when the watch is fully wound and then gradually indicates to a higher number as the watch runs down. This can be thought of as the number of hours that have elapsed since the watch was last wound.
You should always stop winding when the needle on the indicator reaches zero. On most watches, it's possible to wind a little past the zero mark, but the spring was "set-up" to provide the best time-keeping by stopping at zero. Similarly, you should wind the watch before it drops below the 30 mark to keep it operating in the "middle of the mainspring".
Up-down indicator watches are somewhat rare and are highly-prized by collectors.
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.
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.
