 Rod Elliott Clock Information 

Last Updated 04 January 2017

Welcome to my clock pages. The reader may detect a bias here towards electric or electronic clocks, and that is unlikely to change - after all, I've been involved in electronics since I was a in my 'teens, and it's an area where I can contribute the most.

I don't have a vast amount to offer as yet, but new material does pop up at reasonable intervals. While I could take a whole lot of photos of the clocks I've collected so far, I fear that this would be less than enchanting - there are already countless sites on the Net where one can see clocks far more exciting than mine.

As noted, the articles here are (and will probably continue to be) primarily covering aspects of electrical and electronic based mechanical clocks that are not covered elsewhere. While I have many purely mechanical clocks, there are many people who know far more about them than I do, so I'll mainly stick to the areas where my electronics background comes in handy.

For those who think they might be interested in this rather fascinating hobby, the National Association of Watch and Clock Collectors (NAWCC) is definitely the organisation to join. The Australian site is called Aussie Clocks (NAWCC First Australian Chapter No. 72 Inc), and meets every two months.
