Know your chronograph from your chronometer? In this new monthly series,
we define basic watch terms from A to Z. It's our reminder that product
knowledge is a key ingredient to successful watch sales. All terms can be

Analog Display: When time is displayed by
hands rotating on a marked dial.
Automatic or Self-Winding: A mechanical
timepiece that's wound by wrist motion. This motion makes a rotor pivot
around a staff connected to the mainspring through a gearing. A clutch mechanism
Bezel: The ring that surrounds the watch
face and holds the crystal in place. It can be stationary or rotating and
can have special functions, such as indicating minutes on a diver watch.
Calendar: The device that shows the date,
day of week, month and/or year. The display can be digital or analog.
Chronograph: A stopwatch that measures continuous
or discontinuous time intervals. It can be started, stopped and reset at
will with push buttons. When used with specialized scales or subdials, it
can perform many functions (see Professional Jeweler,May 1998 p.106),
including tachometer, telemeter and pulsimeter. Different from a chronometer.
Chronometer: A timepiece movement that received
a certificate after passing stringent tests under varied temperatures and
positions. The most renowned test organization is COSC (Contrôle Officiel
Suisse des Chronomètres).
Crown: The button on the outside of the
watch case used to adjust day, date and other functions. On a hand-wound
watch, it's also used to wind the mainspring and is called the winding stem.
Crystal: The "glass" cover of
the watch. It can be made of glass crystal, mineral crystal or sapphire
crystal. It's often treated on both sides to minimize reflections.
