I made this video to provide a broad understanding of all the Seiko Automatic Self-Winding movements. My goal was to make a video that is informative without going into deep technical detail.
List of Calibers mentioned in this video by order:
0:00 Intro
0:30 Scope
1:43 7S
2:36 4R
4:39 6R
6:49 6L
7:43 8R
8:42 8L
9:53 5R
10:40 Outro
Accuracy Metrics:
Most of the time watches will be more accurate than the stated movement accuracy. This is because the stated movement accuracy is just the manufacturer’s minimum accuracy guarantee.
