The portion of the case covering the back of the watch.

The pawl which prevents the ratchet wheel from turning backward when the mainspring is wound.

Two pins, sometimes adjustable, which limit the side to side motion of the pallet fork. Adjusting the banking pin also controls the amount of slide of the escape tooth on the pallet jewel

The inner cover on the back of a watch case. Typically found on hunter-case watches.

The amount of the unrestrained motion of the escape wheel as it leaves one pallet jewel and drops onto the locking surface of the other pallet jewel.

The two regulator pins which "pinch" the balance spring and govern the fine-timekeeping of the watch.

An acrylic crystal composed of plastic composite that is generally less expensive than a glass or mineral crystal. Sometimes called an "unbreakable" crystal, though this is a misnomer as they can definitely break. A high-quality acrylic crystal has optical properties very similar to glass.

Also called self-winding, A mechanically powered watch that is wound by the motion of the wearer's arm rather than through turning the winding stem (manual mechanical). In response to this motion, a rotor turns and winds the watch's mainspring. If an automatic watch is not worn for a day or two, it will run down and need to be wound by hand to get it started again.

This term refers to a precision watch that is tested in various temperatures and positions, thus meeting the accuracy standards set by C.O.S.C. in Switzerland. These watches are provided with a chronometer certificate detailing specific test results by the C.O.S.C.

The "face" of the watch. Most commonly made of metal, or glass-like enamel on a metal substrate (often incorrectly called porcelain). Can also be made from a wide variety of exotic materials and metals.
