Citizen Radio Controlled Watch


cal. H145

Factory Spec. 15 SPM

I acquired this watch as a stand-by time reference for the purpose of timing my HAQs when not near a computer. Unfortunately, although my position in Hong Kong is technically covered by the Chinese atomic clock (and some people, here, even report being able to pick up one of the Japanese signals), I cannot get reception. It works at my parents' home in southern England, but its inherent accuracy is so poor that it is useless as a time reference unless it has only just been synch'd.

It has got some nice features, though. The hour hand sets itself automatically when you choose the time zone. The second hand resets to 12 in the event that you should need to manually set the time. The positions of the minute and hour hands remain constantly relevant to each other. The calendar is perpetual. The watch can be set to automatically adjust for DST. Oh, and the whole thing is solar-powered and Duratec-coated.

Some details of this watch are missing as it is kept several thousand miles away, in the UK.
