Seiko EL-330 Full Maintenance - An Electronic Watch from 1970s

Hi, in this video, I'll try to overhaul a Seiko electronic watch. This is a hybrid watch that has both electronic and mechanical parts. The movement is Seiko 3303A. This is an early version of Seiko electronic watches. The challenge was I couldn't find any reference about this complicated movement. I managed to assemble it by trial and error, I might do something wrong. If you have any knowledge about this movement, please share it with us. Thank you for choosing this video. I hope you enjoyed it. If you like this video, please hit like and subscribe to my channel!
