FIELD: physics.
SUBSTANCE: chronometer with world time function contains a mechanism (27, 29, 31, 25, 19, 19H, 19E, 20, 20H, 20E, 21, 21E, 21H, 22, 22E, 22H, 23, 23E, 23H, 11, 11A, 12, 12A, 13, 13A, 14, 14A, 15, 15A, 17) of winter / summer time switching, which can be intermittently driven by the clock mechanism for selectively moving individual geographic reference points located on a dial (3) by 1/24 turns to change local time by one hour for these geographic reference points when switching from winter time to local time or from summer time to winter time.
EFFECT: improved accuracy.
