Measuring altitude Measuring altitude

2.5 m hand indication
Indication range: ‒97.5 m to 97.5 m
The 100 m hand points minus indication when measured altitude is lower than 0 m.
In this case, use figures in parentheses to read the 2.5 m hand.
On the example in the right, the last 2 digits of measured altitude are indicated as “40
m” or “‒60 m”.
Measured altitude is indicated in 5.0-m height
when it is more than 6 000 m.
When your watch has the scale, setting the
mark on the scale to the position that the 2.5
m hand points makes it easier to determine
altitude difference at the next altitude
measurement.
