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




Train side






Bridge off showing train wheels






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.
