How to deal with these tiny correctors?

[Kalanag]

Does anyone know how (in which direction) to press out these tiny correctors in the case of a triple date ladies watch? I don‘t want to damage them.

Can I source these correctors anywhere? Neither Cousinsuk nore Boley have those small correctors in stock.

OD is about 2mm, length is 2.5mm.

Details of the watch to be found in this thread: eta-2898-2-documentation

They look like they should be push out 

No idea where you would by new ones from though

I assumed that these correctors have to be pushd out from the inside of the case and 3D-printed an appropriate tool which I used in combination with a pair of parallel plyers. It worked!

As to the question of sourcing such pushers I found that there are dozens of case specific variants. Cousinsuk has a 100 pcs set which doesn‘t contain the right item. I also found a French supplier who offers a set of 11 different so called „hidden“ pushers which are very similar to my version. But none of those has exactly the right dimensions for my watch. So I finally have to reuse the old ones which are worn badly.

I would attempt turning one on a lathe. I turned a pusher for a Vulcain Cricket.

Nice work 3d printing thectool!

Respect! I’m far from being able to turn such a 1,8mm thingy with a tiny spring inside.

Oh, I didn't see the spring...that makes it a bit of a challenge

Depending on how thick the walls of the pushers are, you MAY be able to use a lathe to turn down the pusher to size, as long as it’s not too different in size. May be worth a consideration?

The OD of the most similar pusher (No. 205) is about 0,3mm off and the length doesn‘t fit either
