Four Seiko watches in super slow motion to illustrate two levels of "Hi-Beat" technology. Left to right:
10-beat (3600 A/h) Lord Marvel
8-beat (28,800 A/h) King Seiko
5-beat (21,600 A/h) 7S26
1-beat quartz
It starts at normal speed but slows after that. Count the number of times the seconds hand ticks on each mechanical watch compared to the quartz on the right.
