This lovely Stowa was sent in by Caleb from Australia. It has an AS 984 movement, and that classic “Bauhaus” look that it shares with the Nomos Tangente.
The case is a bit battered, and there is some dirt, but let’s see what we can do…
A lovely movement, with a separate cock for the escape wheel. No shock protection, so this is an earlier version.
The case back is perlage decorated.
A 15 jewel movement with sub-second.
In order to be able to clean the jewels, I take the balance cock apart.
Escape wheel cock and wheel bridge removed.
The barrel bridge.
Taking the bottom plate apart.
After going through the cleaning machine, I store the parts in a dust proof container awaiting the new mainspring.
Which arrived today – so I start off by putting the new mainspring into the barrel.
I start with the barrel bridge, and then put the wheels in.
I oil the cap jewel and put the balance cock back together.
Top plate complete, and the balance is moving already. Everything nice and clean.
Now for the bottom plate. Note the minute markers at 8 o’clock – this is so you can put a minute hand on and check the movement without having to put the dial on.
The hour hand is to loose, and I tighten it a bit with the staking set.
The dial has typical damage from people removing hands without the appropriate tools … but for the age of the watch, the dial is quite good.
A lovely dress watch worn with a nice black leather strap.
Hello,
Nice job, I get a 40’s watch with an AS 984 do you know if there’s an oiling chart for it ?
Thank you,
Georges
Just oil as usual.
Ok thank you , do you know if some ETA 984 parts can be used with the AS 984 ?
Hi, nice work! I purchased a 1939 Rotary Super Sport anti magnetic, it was drenched in oil and missing the clicker screw, it’s ready for reassembly, would you know where I would be able to find the clicker screw? Thanks!
You will most likely have to use a generic screw.
Hello
Which way does the screw on the barrel undo. I am reluctant to put too much pressure on it in case it is a right hand thread.
Cheers Andy
Hi Andy,
I don’t remember, but carefully try both directions.
Thanks Christian, I am not game enough to put any more pressure on the screw so I’ll just have to clean the barrel as a complete unit.
Andy
Both barrel and ratchet screws are left-handed on the AS984 movements I’ve cleaned.
This may be a stupid question, but how did you get the movement out of the case. I picked up a similar stowa and pulled the crown as usual, and the movement is now free spinning in the case, but I can’t for the life of me figure out how to remove it.
The movement comes out through the front. You have to remove the bezel ring.
Best regards,
Christian
Hi, thanks for the post! Very helpful. May I ask you where you ordered the new mainspring? I have a watch with the same movement (AS984) and broken spring… Many thanks. M.
I got the mainspring at cousinsuk.com
Many thanks for the link!

Thank you for another interesting “pictorial lesson”. How does the staking work to tighten a hole?
Cheers again
You very slightly compress the centre of the hand, and that makes the hole a tiny bit smaller – normally, a slight tap on the stake does the trick.
