In this video I fix a Seiko Kinetic watch by replacing the capacitor battery, an easy fix.
The exact model is Seiko Kinetic 5M62-0CW9. The matching part is 30235MY. The watch is 9 years old, not 15 that I wrote inside, and usually the capacitor battery doesn't last that long.

I cleaned the watch head with alcohol, and the bracelet with boiling water and alcohol.
