WatchOtaku : hi-beat


A hi-beat (or high-beat) watch is one that beats at 36,000 vph, or 10Hz. First introduced in the waning days of the sixties, they are harder to make but can be more accurate. The higher rate causes all sorts of problems, though, so they're quite rare.

According to the 36000bph site, there were nine efforts to make a hi-beat movement. Good read.
