Timepieces:Data & Statistics
Selling Terms, Part IV
Our series on timepiece definitions continues as a teaching tool for
new sales associates and a review for longtimers
In this monthly series of timepiece facts, begun in May, we define basic
watch terminology from A to Z. The series is our reminder that product knowledge
is a key ingredient to successful watch sales.
All terms and diagrams can be found in The Complete Guide to Watch

A movement powered by a quartz crystal and a battery. This synthetic
crystal oscillates 32,768 times per second. See drawing at right.
Rotating Bezel: A bezel that can
be turned. There are two variations. A unidirectional bezel in diver watches
rotates only counterclockwise for safety. The bidirectional bezel is used
on pilot watches as part of a slide rule for many computations, such as
fuel weight and consumption.
Rotor: The part of an automatic watch
that winds the movement's mainspring. It is a flat piece of metal, usually
shaped like a semicircle, that swivels with the motion of the wearer's wrist.
Sapphire Crystal: A transparent,
shock-resistant and scratch-resistant synthetic sapphire covering that's
used to protect the face of a watch. It's often found in watches of higher
Screw-Lock Crown: A crown that has
to be unscrewed before winding the mainspring or setting the time or date.
This device, coupled with a ring around the winding stem inside the case,
contributes to the water resistance of the watch.
Second Time-Zone Indicator: A subdial
with only an hour hand that can be set to indicate the time in another location
of the world. Only the hour hand is necessary because the minutes do not
change: if it's 1:08 p.m. in New York, it's 7:08 p.m. in Paris (Daylight
Savings Time notwithstanding).
|The gear train conveys movement to the hands through the dial
train. The analog dial displays the time of day.|
Split-second chronograph: A chronograph
with two seconds hands, allowing you to time two events that start simultaneously
but end at different times. The first hand is started, stopped and reset
with one push-button. The other hand has its own button. When the chronograph
is started at the beginning of a race, for example both hands
start simultaneously, one on top of the other. When the first competitor
passes the finish line, you push the button of the split seconds hand and
it stops; the other seconds hand keeps going. The first competitor's time
is recorded. When the split seconds hand is restarted, it catches up with
the regular hand. When the second competitor passes the finish line, the
operation is repeated, and so on.
