completely to position (
p2
): the
seconds hand stops.
2.
Set the time by turning the crown in the desired
direction.
3.
Push the crown back in completely to position (
p0
):
the seconds hand starts again, allowing perfect
synchronization with a time signal.
Setting the date and the universal-hour indicator disc or the
24-hour hand (according to model)
1.
Pull out the crown
C
to position (

).
2.

4.1 Screw-in crown
On certain models the crown
C
is screwed in to guar-
antee optimal water-resistance. It must be unscrewed
to make adjustments. After adjustments make sure it
is screwed in again.
> Please note that water-resistance is only guaranteed
when the crown is screwed in.
4.2 Telemeter
Scale showing the distance traveled by a sound in a
certain time. For example, to measure the distance
separating you from a storm, start the chronograph
when you see lightning and stop it when you hear the
resulting thunder. A measurement of 3 seconds gives
a distance of 1 km on the telemeter scale.
4.3 Tachymeter or Tachymiler
Scale showing the average speed of a vehicle. Using
the chronograph Start-Stop function, measure the time
taken to travel 1 km or 1 mile. The average speed can be
read on the tachymeter or tachymiler scale.
Example: 1 km or 1 mile traveled in 20 seconds = 180
km/h or 180 miles/h
4.4 Helium valve
The helium valve is intended for divers spending several
days aboard a diving bell. The air in diving stations or
diving bells is enriched with helium to facilitate breath-
ing. Helium has the capacity to penetrate into the watch
through the joints. But unfortunately it does not escape
the same way. To permit the excess pressure to escape,
the helium valve is opened during ascent.
4.5 EOL function
Indication of the end of battery life. If the seconds hand
starts to move in 4-second steps, the battery should be
changed by your Hamilton agent.
4.6 Power reserve
Indicator for checking the running reserve of your au-
tomatic watch.
4.7 GMT
Greenwich Mean Time is the global time system that
remains the same all year round. GMT in the watch in-
dustry refers to a timepiece that shows two or more
different time zones on the dial at the same time.
4.8 Moon phases
An indicator that keeps track of the phases of the moon.
Once set, the moon phase indicator accurately displays
the phases of the moon.
4.9 COSC
“Contrôle Officiel Suisse des Chronomètres” (official
Swiss chronometer-testing institute) - a Swiss testing
laboratory that certifies watches, or rather their move-
ments, as “chronometer”. Each movement is individually
tested over a 15-day period in different positions and
temperatures, and passes only if it shows a loss of fewer
than five seconds per day.
4.10 Elapsed time on the exterior rotating
bezel
Scale for measuring elapsed time.
1.
Turn the bezel
F
counterclockwise until the arrow
points to the minutes hand.
2.
The minutes hand will indicate the elapsed time on
the graduated scale of the rotating bezel.
4.11 Countdown function
1.
Unscrew the crown.
2.
Turn the crown so that the desired countdown time
points at the minutes hand.
3.
Screw the crown in again.
4.
The countdown is at zero when the minutes hand
is located over the marking (in the form of a watch
hand).
