Seiko King Quartz 5855-8010 Maintenance
Тәжірибелік нұсқаулар және стиль
This time, we will work on a Seiko King Quartz from the 1970s. No dramas.
The movement is Seiko 5855A, which is a high-quality quartz movement. This was priced higher than the mechanical movement model, King Seiko. At that time, quartz watches were a luxury item.

Beautiful quartz caliber
I find the second stop/skip mechanism pretty useful and use it on my 5856 KQ. It's accurate enough (6 seconds fast/month) that adjusting it a second or two every once in a while keeps it running spot on without needing to stop the watch.

Wow, thank you for telling me about the usage. I adjusted it right away. My one is 10 seconds late/month, worse than yours but enough for me :)
I can normally keep up with reassembly with Swiss movement but this was so alien to me. Beautiful movement though.
Is it me or are these gears in train of wheels much smaller than in a 'normal' mechanical watch?

Quartz watches usually have smaller wheels, the stepper motor has much less torque than a mainspring.

Yeah, they are much smaller than normal mechanical gents' watch parts but larger than ladies watch parts.
What was the problem? Just dirt/oxidation?

Old oil/grease probably jammed the pivots and jewels.
