1) Lets start with the old. The very knowledgeable and true gentleman Mr Petro Protopapas was in Hong Kong this week and I had a great chat with him. He brought some very interesting collection with him. This stop watch is run by an ultra high frequency movement. One can hear the bee buzzing sound when the Start button is activated. It also comes with an anti -tempering case for the watch to be cased, and the only button available is one for the time keeper to stop the time. A quick iPhone pic:
