Removing the winder pin from the mechanism - Help!

[thegobetween]

Morning,

I have my old Tag F1 which I need to replace the mechanism on (corroded!!). I'm trying to find a beater on eBay to swap the mechanism with but wondered how you remove the winder pin to allow removal from the body.

Any help would be appreciated.

Pull the crown out, and on the inside edge of the movement next to the stem base there will be a release button or screw.
Usually 1-2mm offset to the side of the stem base

Thanks.

I had a look but couldn't see anything. I guess its only a cheap sourced (ETA?) movement; are all stems removable?
