An "Automatic movement" does not need a battery. The mechanism
winds itself by the movement of the wearer. Therefore, the watch never
needs to have the battery changed. An "Automatic" watch
usually cost more than a "Quartz" watch. Most watches have
matching styles for Quartz and Automatic.
A strap is simply a watchband made of leather, plastic or fabric.
A "Bezel" is a ring on the top side of the "Case"
around the "Crystal". The "Bezel" can be turned
either way called "Bi-directional", or more popularly one
way (counter-clock wise) called "Unidirectional". The purpose
of the "Bezel" is to be able to begin timing an event at
any given time by aligning the bezel's #12 at the beginning point.
Bi-directional Turning Bezel:
A bezel that turns both ways, counter clock wise and clock wise.
The traditional Loop and Pin is called a "buckle".
A bracelet is the flexible metal band consisting of assembled links.
Detachable links are used to change the length of the bracelet. Bracelets
can be made of stainless steel, sterling silver, gold or any combination.
A "Case" is the total housing of the watch, excluding the
strap or bracelet. The case houses the dial (face), movement and crystal
The Swiss Official Chronometer Control - consists of three independent
A watch with two independent time systems: one indicates the time
of day and the other measures brief periods of time. Counters registering
seconds, minutes and even hours can be started and stopped as desired,
enabling exact timing of an occasion.
A watch that is a certified "Chronometer" has passed vigorous
tests that demand the watch stands up to the high standard of precision
the COSC demands(Swiss Offical Chronometer Control). The mechanical
movement must be close to perfection.
The "Crown" is known better as the adjustment knob or as
the "Winding Knob. On a quartz and automatic watch the
crown is used to adjust the time and/or date. On a manual watch, the
crown doubles as the winding mechanism to power the watch.
The "Crystal" is the glass that you look through in order
to see the "Dial" (face). The purpose of the crystal is
to protect the dial. The crystal can be made of glass, plastic, or
a scratch resistant synthetic material called "Sapphire Crystal".
A "Deployment clasp" is a feature that most quality watches
with metal or gold bracelets use to tighten the bracelet to the wrist.
The regular "clasp has two pieces of steel that clip safely
beneath one long elegant looking piece of steel thus tightening the
bracelet. All manufacturers have slightly different versions and features.
The "Dial" is the face of the watch showing the time. A
blue dial means the face color of the watch is blue. Sub-dials are
smaller dials set into the main face of the watch. These can be used
for added funcions, such as elapsed times and dates, and sometimes
these sub dials are a different color.
The "Display" is the term used to describe the way a watch
displays the time. An "Analog Display" will show the time
by two hands sweeping the dial.
End of Battery Life Indicator:
The EOL indicates when it is time to replace the existing battery.
Different manufacturers use different methods to indicate a low battery,
i.e. if a second hand usually sweeps, when the battery is low it will
begin to tick.
The "Finishes" of watches are of three types 1)Shiny/polished
surface - means it is shiny, has a high gloss & is reflectant.
2) Brushed/mott finish surface has a low gloss and non-reflectant
look. 3) "Gold Plated" finish is a thin layer (usually around
5 microns) of gold elctroplated to stainless steel base.
"Function" is a term used to describe the different tasks
each time related component performs. i.e. the date "Function"
is the date task the watch performs.
Watches with steel or gold bracelets made of individual attached pieces.
Each individual piece is called a "link".
"Luminous hands and/or hour markers"- is a standard feature
on many watches. The hour markers and/or hands have a coating of "Glow
in the Dark" which will illuminates in the dark so you can tell
the time where there is insufficient light.
A "Mechanical Movement" is a watch's mechanism that is powered
by a manual activity such as being wound up by hand or by the movement
of the watch.
The "Movement" is the motor of every watch. The movement
controls all movement aspects of the watch such as the time, date,
escape valves, chrongraph functions etc.
Power Reserve Indicator:
This feature indicates when the power resource of a mechanical
movement watch is low and soon the watch will need winding.
A quartz movement is a watch with a mechanism powered by a "Quartz
Crystal". The crystal vibrates when placed in a electronic field,
thus powering the watch. Most affordable watches today have quartz
movements. Quartz watches are mostly battery operated.
The "Sapphire Crystal" is a type of glass that covers the
watch dial (face). Sapphire crystal is a made of a synthetic material,
which is extremely durable, shatter proof and scratch resistant. Therefore,
sapphire crystal is popularly used by all manufactures for most of
A crown that ensures water resistance to a depth of 660 feet. The
crown is protected from accidental damage.
Unidirectional Turning Bezel:
A bezel that turns in only one direction (counter clock wise).
A watch that is water resistant can withstand water to a certain extent.
When a watch is deemed just "water resistant" it usually
means that the watch will safely withstand splashes of water. A watch
deemed "water resistant 30m", means that the watch can be
immersed into water up to a depth of 30 meters or 99 feet. Some watches
are water resistant up 1000 feet. Check the watch manual to find out
the exact level of water resistance your watch is. The "Water
Resistant" feature is common on most watches.
