ROTATING BEZEL
The rotating bezel can show the elapsed time up to 60 minutes. By setting it before
diving, you can know how many minutes you are underwater.
Start(10:10 AM) " " mark
30 minutes have elapsed.
"30" on rotating bezel
1. Turn the rotating bezel to align its " " mark with the minute hand.
* The rotating bezel rotates with clicks. With each click, it turns half a minute.
2. To know the elapsed time, read the number on the rotating bezel that the
minute hand points to.
To prevent accidental rotation, the rotating bezel is so designed that
rotation becomes harder in water. Also for safty's sake, it roatates only
counterclockwise, so that the time measured is never shorter than the actual
elapsed time.
Minute hand
Example:
Bezel rotation may become slightly stiffer underwater. This is not a malfunction.
TACHYMETER
(for models with tachymeter scale on the dial)
l Tachymeter scale can be used only when the time required is less than 60 seconds.
TO MEASURE THE HOURLY AVERAGE SPEED OF A VEHICLE
Use the stopwatch to determine
how many seconds it takes to
go 1 km or 1 mile.
Tachymeter scale indicated by
the STOPWATCH 1/5-second
hand gives the average speed
per hour.
Ex. 1
STOPWATCH 1/5-
second hand:
40 seconds
Tachymeter scale: "90"
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or
miles and the STOPWATCH 1/5-second hand indicates “90” on tachymeter scale:
"90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
"90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph
