SLOM was ace. They're all available freely online with Tim Hunkin's blessing: http://www.exploratorium.edu/ronh/SLOM/ . Have been watching them through again with my (slightly bemused) girlfriend, prompted by seeing his mad clock at the London Zoo.
Anyway, my £85 Citizen is bestest because:
– it's made of titanium
– it has the crown at 8, ideal if you wear it on your right wrist
– it's an automatic so no batteries to wear out
– the seconds hand sweeps round in that rather lovely way that only autos can
– having hundreds of tiny cogs and springs in a little case on my wrist seems quite magical. The fact it can actually keep good time is even more remarkable.
