The purpose of rotating watch bezels,
which are often associated with Scuba
diving, is to keep track of elapsed time,
or to make other measurements, such as
average speed or distance traveled.
Rotating bezels take advantage of a
watch's primary function--timekeeping--
to allow the wearer to keep track of
something other than just the hours,
minutes and seconds of the day.
Definition
A bezel is the ring that surrounds the
dial, or face, of a watch. Commonly
constructed of gold, gold plate or
stainless steel, the bezel may be adorned
with diamonds on a jewelry watch. On
sports watches, it often has calibrated
markings and the ability to rotate in
either one or two directions. Although
rotating watch bezels perform
timekeeping functions, the primary
purpose of the bezel is to hold the crystal
covering the face of the watch in place.
Unidirectional Bezel
As the name indicates, a unidirectional
bezel is one that rotates in only one
direction--counterclockwise. This type of
rotating bezel is often used for scuba
diving. Prior to submerging, a scuba
diver with 45 minutes of air in his tank
could turn the bezel so either the zero
mark or the 45 mark is showing,
depending if it is a count-up or
countdown gauge. That lets the diver
know how much air is left with a quick
glance at the watch, rather than
subtracting the starting time from the
current time to determine how many
minutes have elapsed or how many
minutes of air are left. The bezel on a
diver's watch is often ratcheted to
prevent it from accidentally being
knocked out of its original position,
which could be disastrous for the
wearer.
Bidirectional Bezel
This type of bezel moves both clockwise
and counterclockwise, enabling it to be
used either for mathematical calculations
or for measuring how much time has
elapsed or how much time is remaining.
Tachymeter
Watches with a rotating bezel that serves
as a tachymeter help the wearer
calculate their speed of movement based
on travel time. For example, the wearer
starts the chronograph, or stopwatch
function, at a mile indicator and at the
next mile indicator the point on the scale
where the second hand lies shows his or
her miles per hour speed. It can be used
with any unit of distance, as its purpose
is simply to measure units traveled by
hour.
Slide Rule
A slide rule bezel features logarithmic or
other scales on the watch face's outer
edge, enabling the wearers to perform
mathematical calculations. The rotating
bezel is marked with one scale and is slid
around the stationary scale to make
calculations of various types, which
depend on the watch. Some models are
designed for calculating how much fuel
an airplane has used or the fuel weight.
There are a number of different DKNY watches available for women. They have everything from classic wrist watches to jewelry watches. They even carry ring watches.
Usually on your wrist, but people wear watch chains on their belts or in their pockets for pocket watches, they make keychain watches, armband watches, and even finger/ring watches.
Automatic and kinetic-movement watches do not have pendulums. However, in its place they have a semicircle-shaped rotating weight called a rotor. The rotors in automatic watches will wind the mainspring. Kinetic-movement watches' rotors are connected to a generator that will charge a battery.
I wouldn't buy an engagement ring from tag Heuer for your girl unless you want her to wear it around her wrist. I would stick to them for watches and go to engagement stores for the ring.

No, it is merely the plural form if the common noun wrist watch
