Chronograph pusher removal?

[Len33]

I need to replace the pushers on a chronograph, but I'm not familiar with how they are fitted.

From the pictures, can someone please tell me the way to procede?

Thanks.

This video of Marks shows how to fit a chronograph pusher obviously removal is the reverse of the operation:

Thanks for your suggestion, but I had already seen that video.

The problem that I have, is that the end of the pushers on my watch do not have a screwdiver slot in them.

I did try to make that clear in the picture but, using an ipad, it wasn't possible.

Anyway, 'thanks' again.

How about a hand drawing to show what your camera lacks the resolution to.

Identifying the watch, brand ,case etc helps too.

Push the pusher in fully and you should see a miniscule c-clip.

 

Under magnification, put a dab of rodico or blue-tac under the clip and push down with a small screwdriver or the proper c-clip tool to remove it.

The Rodico/blue-tac should stop you losing the clip.
