Paul sent this one in – it’s his wife’s watch. Not only is it losing quite a lot of time, the crown comes out when you pull it…
The calibre 1020 movement.
I start off by removing the day wheel, and work my way through the bottom plate.
The crown slipping out is due to a worn pin on the set lever – I have a used one in stock that is still good.
Now I put the movement back together – the balance is swinging already. The auto-winder assembly goes on last, as you can’t put the second hand on with it in place. You have to support the second hand arbor from the back when pressing it on.
I adjust the beat rate and beat error – all is looking good!
A great looking Seamaster!
Now it’s time to clean the bracelet and put it back on.
The bracelet pins get a bit of a tightening, and we’re back in business.
