Summer time

Automatic switching of summer time setting

This watch can change summer time/standard time indication automatically when it receives time signals including summer time signals.

When the automatic summer time switching function is activated, the time indicated is automatically switched to/from summer time depending on the summer time signals in all the time zone areas except for “UTC”.

!

Actual signal reception is executed only for the area set for time of the analog indication, so, actually, settings for all areas do not change at the same time.

!

In some areas, owing to the automatic summer time switching function, summer time setting switches synchronously even when they are not set as the area of the analog indication.
For details, see “Link of summer time setting“ below.
