Cal. H145 VS H144:

The H145 and H144 both share the same user manual. They are very similar movements, with the main difference being how they handle daylight saving time (summer time) settings.

The H145 will remember the daylight saving time of the most recently received time signal – unless the daylight saving time has been overridden manually. In other words, if the daylight saving time was manually set, then it won’t be updated automatically according to the time signal.

With H144 powered watches, if the time signal indicates daylight savings time, it will override the manual setting.
