Update: 89ST Series Stopwatches - Olympic Sports Timers

I have added some videos of the movements in operation to the main article on the 89ST series of stopwatches. I have also included a short slow motion section to make it easier to see the movements. You will note that the 890C when slowed down to 5% of normal speed is still at 18,000 bph, the same speed as the 890A operating normally.

If you have already seen the main article below are just the videos that have been added.
