About This Manual
• The display of this watch uses two LCD panels that
make it possible to display mode icons, numbers formed
with segments, dot matrix characters, etc.
• Button operations are indicated using the letters shown
in the illustration. Keypad keys are indicated by their
main keycap markings within square brackets in bold,
such as [2].
• Each section of this manual provides you with the
information you need to perform operations in each
mode. Further details and technical information can be
found in the “Reference” section.

Mode Menu screen (by pressing C), and then press the

zone or another city, or Greenwich Mean Time.

actually eight different time zone indicators, two groups of
