I took this from a watch booklet and only lifted up the relevant points so that it is easy to refer. You can get to know and appreciate the mechanical watch
.
A
Acryl crystal; Chemical description: Polyacrylmethacryl acid squaring. Material for watch crystals also known as "plexiglass". Acryl is easy to process. It can be filed, polished or bent. The advantages of Acryl are high resistance to shocks, anti-allergenic qualities, its malleability and the price. The disadvantage is that due to the weakness of the material the surface is liable to scratch. However, light scratches can be removed by polishing.
Amplitude (Vibration); Angle of oscillation for the balance.
Antimagnetic watches; Watches not, or hardly affected by magnetic fields. For the balance springs of the balance non-magnetic nickel alloys are used.
Automatic; Synonym for a watch with automatic winding. The movement of your wrist makes the rotor (oscillating weight) turn, thereby winding up the mainspring of the watch movement.
B
Balance Spring; The hairspring and the balance form the oscillating system. The balance spring of some mechanical watches consists of a thin and flat wire made of Nivarox.
Balance Wheel; Part of the escapement of a mechanical watch. Oscillating device which divides the time into equal sections.
Barrel; The barrel contains the wound-up mainspring, hooked to it at its outer end and which stores the energy, assuring a power reserve of 36 to 45 hours to the watch. The mainspring is wound up manually by means of the crown (handwinding watch) or through the movement of the oscillating weight (rotor) in an automatic watch.
Bridge; Brass plate fixed on the main plate by two or more pins and screws. Between the bridge and the plate the wheels and staffs are turning.
Bezel; Top ring for the crystal and/or decorative ring on the upper side of the watch case.
C
Calibre; Description for a watch movement according to construction, size and factory origin.
Carbon fibre; Carbon fibre is used for reinforcing polymers. This is the most frequently used compound, followed by glass fibre. It is used if a light but strong and stiff material is needed, for instance for racing cars, or in astronautics, or for sports equipment. In the watch industry this compound material is employed for dials and cases.
Chromium; White hard metal (chemical symbol Cr) used by the watch industry in alloys to coat cases.
Chronograph; Wrist or pocket watch incorporating an additional stop mechanism (start, stop and back to zero functions).
Chronometer; A watch of extremely high precision and accuracy, tested in several positions and under different temperatures and which has obtained an official rating certificate.
Complication; Additional functions to a watch movement, e.g. chronograph, second time zone, alarm, calendars, etc.
Crown; Button to wind up and set the watch to time.
