Classicwatch Vintage Watches

Hello,

I got this JLC. I think it is the caliber bumper 476 and would like to have more information about it.
The watch should be unserviced, so I will have to find someone to do it.

For its use, does it look that some part were/needs to be changed, is it splash proof ? When opening it, I saw that the gasket is still here.
It looks like I'm able to manual wind it, is there a protection against over winding ?
If so, would that watch compatible with a winder?


The case doesn't look like it have any number inside.
I found the serial on the movement and on the back case.
Looks like I can't post many pictures at once, so I will send by replying.

Thanks in advance.

Hard to say if anything was replaced without more photos.

My post was under moderation, I'm now sending more pics,

sorry about flooding, there will be 3 messages for 3 pics.

Edit, we don't see it on my pictures, but the crown is signed.
