What is this movement and how to remove the crown ?

[ctmoa]

Hello.

I would have to know what is this movement type or name (it is for a breitling navitimer tricompas 6-9-12).

And more important, how can i remove the crown ?

Because there is no hole near the crown where i can push to remove the crown.

(and if you have the complete process to remove this movement, it will be perfect).

Thanks for your help.

Gently push in the little dimpled pin to the left of the stem while pulling the crown outwards from the winding position.

What is all that crap in there, Sand????

I am not familiar with this movement, but comparing to the ones I have removed, I would suggest pressing the small 'button', just to the left of the winder cog with a small watchmakers screwdriver, and gently pull the crown to remove it

I don't understand why i haven't succed whith this small button. But you are right. It is this button.

Thanks for your help.

For the 'crap' on the watch, it is because i have brushed the case.

And it seems that some 'crap' rest was on the cloth where i put the watch.

And maybe static electricity have made this.

After taked picture, i have blowed on it, and it seems to be ok.
