Movement
Functions
The Reverso Squadra Hometime watch model features a
double set of hands allowing the local time on the main dis-
play to be changed rapidly by moving the corresponding hand
forward or backward in 1-hour jumps, while maintaining a
reference time thanks to an additional hour hand.
It offers the following functions :
- Local time adjusted rapidly and independently in both
directions (time zone of the local city).
- Date synchronised with local time; can be changed in both
directions.
- Reference time.
- AM/PM indication linked to the reference time.
You may use the local time and reference time displays as you
wish, for example :
- To indicate the same time in the local time display and
reference time display; the two hands are placed one over
the other and the watch offers a classic display.
- To set a different time on the main display while keeping
the reference time indication on the additional hand
(skeleton hand).
- To set the time for another time zone on the reference
time display, so as to keep permanent track of the time
there, with day/night indication (AM/PM).
- To indicate the official GMT time on the reference time
dis-play, so as to deduce any time zone according to its
difference with the reference GMT time zone, and then
display it on the local set of hands.
Whichever option you choose, the local time function enables
you to set the time on the main display rapidly by 1-hour
jumps in either direction, automatically driving the date.
This mechanism thus allows a different time to be set in a few
operations, without losing the accuracy of the minute and
seconds hands.
Use
The crown of the Reverso Squadra Hometime watch allows
you to :
- Wind the watch if it has not been worn for over 48 hours
(crown in position 1).
- Set the local hour/minutes (time zone of the local city) and
the date (crown in position 2).
- Set the reference time, driving the AM/PM indication
(crown in position 3).
Starting the watch
Crown in position 1.
A few clockwise turns of the crown are enough to set the
watch running. It is then automatically wound when you wear
it. Please note that the crown does not lock on winding, even
when the watch is fully wound.
Adjusting the reference time
This is the first setting to be performed because it allows you
to determine the reference time and its AM/PM indication
and set the watch in minutes and seconds precisely, and it
automatically drives the other functions, namely the minutes,
local time, date and AM/PM indication.
Pull the crown out to position 3.
The movement is then locked («stop seconds» function).
To enable precise time setting to within one second, stop
the seconds hand in a vertical position so as to indicate 60
seconds.
Move the reference time hand and the minute hand forward
or backward until the desired time is displayed, while taking
into account the AM/PM indication.
