bugshaw at 12:15am on 01/11/2006When buying my watch, they needed to remove a couple of links from the strap, which was a fiddly operation which took them a few minutes with a very small hammer. This gave me time to admire the display of pendulum clocks behind the counter.
One clock caught my eye - quite modern, a glass plate with clock face and a stainless steel disc pendulum which was quite hypnotic. However, the pendulum swing seemed unrelated to the ticking motion of the second hand. Every five seconds the pendulum had got 180° out of phase with the seconds - five seconds later it was back in phase again. I suspect the pendulum is driven by a motor independently of the timer mechanism. WTF? Hello? Mechanics, anyone??
