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
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
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
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.
