Tachymeter Usage
T
T
The Tachymeter function is used to measure the rate of speed of an
object over a fixed distance. The scale, located either on the top ring or
the inside bezel of the timepiece, will display speed in Miles, Knots, or
Kilometers per hour.
Example of usage: In a driving race, the car
passes the first mile (km) post when the
seconds hand is at the 12:00 position (60
second mark). Commence measurement.
At the 35 second mark the car passes the
second mile (km) post, you will see that the
car travelled a distance of one mile at 100
miles (km) an hour.
Automatic Winding Movement
A timepiece fitted with an automatic winding movement obtains the
power to wind itself by the movement of your wrist. It is important that
your timepiece is adjusted to match the size of your wrist. A loose fit
may result in a loss in capacity of the timepiece to wind itself. When
fully wound, your timepiece has a power-reserve of approximately 42
hours. If the timepiece has not been worn for over 42 hours it is advised
that it be manually wound to ensure necessary power-reserve.
