Timepieces:Data & Statistics
Selling Terms, Part II
New behind the watch counter? This series of basic definitions is
designed especially for you
In this monthly series we define basic watch terminology from A to Z.
The series began in the May issue (p. 120) and continues here with "digital
watch." The definitions are a 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 Distribution
and Service, available from the Federation of the Swiss Watch Industry,
Rochelle Park, NJ; (201) 291-8811, www.fhusa.com.
Digital Watch: A watch that displays
the time by numbers or digits instead of hands.
Escapement: Device in a mechanical
watch that controls the rotation of the wheels and the motion of the hands.
Fly-Back Function: An extra second-hand
is superimposed on a chronograph's main second-hand and is commanded by
an additional push-button. To read an intermediate time duration, the fly-back
hand is stopped and then made to "fly back" to rejoin the main
Guilloche (gi-LO- SH or ge--YO- SH):
A type of engraving in which thin lines are interwoven, creating a patterned
surface. This is seen mostly on high-end dials.
Index: A design used to mark a period
of time on a dial, usually the hours, the minutes and the seconds. Markers
can be used also to indicate the remaining hours on a power reserve indicator
or the heartbeats on a pulsimeter. Indexes are used in place of numbers
on the dial.
Jewels: Synthetic rubies or sapphires
used as bearings to reduce friction between watch parts. They also have
the capacity to retain lubricants by capillary action, releasing them little
by little. Many watches have 17 of them, though the number can go up to
more than 60 on collector masterpieces.
Jumping Hour: One of the earliest
digital displays. The hour is shown with a numeral through a window instead
of an hour hand. It is called "jumping hour" because the numeral
changes suddenly on the hour instead of gradually as with an hour hand.
Lugs: Projections on the dial to
which the watch band or bracelet is attached.
Mechanical Repeater: A very sophisticated
device that chimes a different note for each hour, quarter-hour and minute,
depending on the type. Some even chime the half quarter-hours (71/2 minutes).
The minute repeater was invented to accommodate people who, for one reason
or another, needed to know the time in the dark before the advent of luminous
