You asked to see some of Tim's clocks and watches. A recent video showed some of his clocks, and now here are a few of his unusual watches.
The Relativity Watch has a bit of fun with Einstein's theory of relativity. It has the pi symbol instead of a 3. The minute and the hour hand work in the normal way, but the entire clock face rotates by 1/60th of a turn every second. Very strange!
The binary watch has two rows of lights. The top row, which shows the hours, has four lights, which - starting from the right - mean 1, 2, 4 and 8 respectively. In this case the first and third lights are on, i.e. the 1 and the 4, which means it is 5 o'clock. The bottom row shows the minutes, with lights standing for 1, 2, 4, 8, 16 and 32. In this case, the 1, the 2 and the 32 are all lit, meaning 35 minutes. So the time is 5.35. Although as Tim says, when he first got the watch, it took him so long to work out what the time was, by the time he had done it, the actual time had moved on by a couple of minutes!
The next one is a backwards watch. These are quite common now, but when Tim bought this, it was the first time he had come across this idea. The numerals are written the reverse was around the dial, and all three hands (including the seconds hand) go the other way around the face of the watch. With a little practice you can read the time quite easily.
The 'Peaceful' watch (not sure why it is called that) is normal in most ways, but it has two lights built into it. One is a bright white light, useful for finding things in the dark maybe. Or even finding your way in the dark. The other is an ultra violet light. Tim wonders if that could be used for checking banknotes, and things like that. As he says, this watch is quite heavy on batteries!
The World Watch has different time zones marked on it, so it it is 12 o'clock in London, you can see at a glance what the local time is in Paris, Berlin, Moscow, Delhi, Tokyo and so on. It only has an hour hand, not a minute hand.
The last example is a sun dial watch. There is no mechanism, and no batteries. Just a little sun dial where the face of the watch would be. You need the sun to be shining, so it definitely works best out of doors. And you also need to know which direction is North, so you can align the watch correctly. However if all these things are set up correctly, the sun's light will hit the little arm (the gnomon) and cast a shadow on the dial, telling you the time, well, fairly accurately. Tim is still looking for a luminous version of this, so he can use it at night ;-)
