DIVERS SCALE
Located on the turning bezel of the SVT-DW44 dive watch.
Unidirectional Rotating Bezel: The most important feature of any divers watch
and an essential part of every divers equipment is the diving ring. This is a
rotating bezel around the dial or the crystal. It is divided into minutes and often
has a triangular fluorescent marking at 12. Before divers take to the water, they
have calculated the time they can spend under water. The diving time depends
on the depth and the amount of oxygen taken down. When a diver has 45
minutes of air and enters the water at 14:00 hours, the triangular marking has
to be set 45 minutes later, in this case at 14:45. The minute hand has a similar
triangle as the diving ring. When both markings meet it is time to surface
because air is running out.
TACHOMETER
Specific models feature a Tachometer, or Tachymeter, which is simply a function
on a watch that allows the user to measure speed.
A Tachometer is a feature found on some chronograph watches that measures
the speed at which the wearer has traveled over a measured distance. In
matchmaking, it is a timer or chronograph with a graduated dial on which speed
can be read off in kilometers per hour or other units of distance.
