SECOND TIME ZONE (calibre 1128, fig. VI)
Thanks to the “24-hour” hand with its triangular point,
travellers can read the time back home at a glance on
the 24-hour scale on the rotating bezel. In order to do
so, the triangle on the bezel must point to 12 o’clock on
the dial.
The bi-directional turning bezel (calibre 1128)
allows a third time zone to be read. To do so, the bezel
must be turned so that the “24 hour” hand points to this
third time zone on the bezel. When read off against the
scale on the bezel, the “24 hour” hand will then indicate
the time in this third time zone.
In order to read the time back home, the triangle of the
bezel must be returned to point to 12 o’clock on the
dial.
SECOND TIME ZONE (calibre 2628, fig. VII, calibre
3603, fig. XX)
Thanks to the “24-hour” hand with its triangular point,
travellers can read the time back home at a glance on the
24-hour scale at the centre of the dial.
