I'm quite into my servicing the past 8 months. Thought some might like to see a quick clean up and service on a nice little 7009 Seiko I did today, came in the post this morning looking a bit sorry for itself...
Dirty and scratched crystaland running about +60sec
Yummy
Action
Calendar side
Day wheel off
What lies beneath..
All calendar, keyless work and balance jewel removed

Naked
And here's what we're left with
Mainspring out
My method is in lighter fluid in a small tub and placed into my ultrasonic surrounded in water and weighted down..
All clean
Mainspring cleaned and refitted
Mainplate clean and ready for it's parts.
On the way, oiling as I go
Bridge back and train running smooth
Calender side on the way back, balance jewel cleaned and lined.
Once I've refitted the date and day wheels and finished the calender side (except dial) I go back to the train side and fit the balance ass. Shown here after fitting and the jewel removed for cleaning
Jewel cleaned, oiled and back in
Dial back on, hands installed
Case, crstal and bracelet all out the ultrasonic and shines
Bit nicer
Crystal before
Sanded
Polished
Cased back up
These 7009 movements run so well. So much nicer than the newer 7s26 and the like. Did a quick initial regulation and running 0 sec dial up and +2 sec dial down. Will run it a week and check it on the timegrapher again.
Hope someone found that interesting as it took me longer to take pics and post this than the service and clean up.
