Up/Down Wind Indicator
Some of the highest quality pocket watches 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".

Adjustment
Watch adjustment is the process of correcting those errors in the watch that cause variation in time keeping. These include temperature influences, variation in driving power and position of the watch with respect to mechanism such as pendant up or dial up.

Watches with better calibre movements will have been adjusted at the factory for a number of positions. The usual array of positions include a subset of the following positions:
1. Dial up 2. Dial down 3. Bow up 4. Bow down (Not required by Railroad) 5. Bow left 6. Bow right

These positional adjustments are intended to insure that the watch is just as realiable and accurate regardless of the position in which it is stored or used.

In addition to positional adjustments, the watch may also be adjusted for Temperature(heat/cold). Temperature affects different elements in different ways. Heat will cause some metals to expand faster than others, and cold may cause some metals to contract more than others. A watch that is adjusted to temperatures will usually include some combination of metals that allow the watch to maintain its proper functionality within a larger range of temperatures than one that is not adjusted for temperature.

Another type of adjustment is Isochronism. As a typical watch spring unwinds the pressure it exerts on the wheels of the movement reduces. This has the potential to create a difference in the operating speed of a fully wound watch versus the same watch in an nearly fully unwound state. Adjustments for isochronism attempt to compensate for this potential by maintaining the same pressure from the spring throughout most of the operating range of the watch. This sort of adjustment was generally seen only on the finest railroad grade watches of the 20th century.

Jewel Count
Jewels are used as bearings to reduce metal-to-metal contacts which produce friction and wear. They improve the performance and accuracy of the watch and materially proglong its usefulness. The materials used for making watch jewels are diamonds, sapphires, rubies and garnets. The diamond is the hardest but is seldom used except for cap jewels. The sapphire is the next hardness and is the most commonly used because of its fine texture. Garnets are softer than than sapphires and rubies.
