I like clocks I don't ever have to set or re-set. Read into that what you will!
Apparently, not many people in HK are as concerned, because I've never seen one for sale here. Of course, a prerequisite for them to work is an appropriate radio signal for them to receive and synchronise with, and I'm not aware of any such signal being broadcast in Hong Kong.
However, I did bring with me from London an old Oregon Scientific world traveller projection alarm clock, which I had purchased ca. 2007, which, unlike most of these kinds of devices, has the ability to receive several different synchronisation frequencies, including US, UK, EU and Japanese... A review of the relevant Wikipedia page suggested that one of the frequencies in China might be the same as one of these frequencies, but I was pleasantly surprised to discover that my clock can receive one of the Japanese signals with no difficulty at all. Cool!
But I want more. Now I want radio controlled clocks in every room in the house! I suppose I could buy one in Japan? But the Japanese aren't very good with foreign mail-ordering (as my experience with Yahoo! Japan Auctions can attest)... I've always wanted to visit Japan, but it is a little far for a shopping trip! Any ideas? Cheers.
