Tachymeter Usage
The Tachymeter function measures 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 36 second mark the car
passes the second mile (km) post, you will see that the car traveled a distance of one mile at 100 miles
(km) an hour.
Automatic Winding Movement
A timepiece fitted with an automatic winding movement winds 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 60 hours. If the timepiece has not been worn for over 60 hours it may need to be
manually wound to ensure necessary power-reserve.
