Hey everyone. Hopefully someone can help me with this. My wife has a deville prestige with an extremely tiny crown. She wears it all week but never on the weekends, so instead of sticking on the orbita winder like I told her to, she puts it in the watch box and it’s dead by Monday. Now it would be no big deal if she knew how to set it, but she runs to me. The crown is too friggin small for my fingers, and I’m wondering if anyone knows the crown size so I can buy a crown tool. It’s reference 424.23.33.20.52.003. Thanks everyone

 

Crown winders have some overlap in the size of crown that they can grip. Here are the four different options offered by Bergeon:

 

I had no idea this was a thing! This might be useful for a supercompressor I have where the crown is rather recessed.

 

Awesome thank you!

 

To my personal experience, it is more easier to wind smaller crown when you are wearing fabric gloves.

 

I can’t even get a grip on it with my bear paws lol. I just ordered the A version. I found a battery for my calipers and the crown is only 3.5mm. It’s tiny
