• The chronograph 1/10 second scale and hand differ in design
and shape depending on the models.
* Some models have the chronograph 1/10 second scale graduated
on the upper half of the small dial and the hand which is so
designed that both ends can indicate the elapsed 1/10 second.
In that case, read the marker on the scale where either end of
the hand points to.
• After the measurement exceeds 1 minute, the chronograph 1⁄10
second hand stays at the “0” position.
When the measurement is stopped, it will move to indicate the
elapsed 1/10 seconds.
