Hello, I'm trying to replace the gasket for my Constellation (168.029).
I know that the diameter is 31.6mm for this one and it requires a thicker gasket.
I see a 0.80mm and a 1.00mm for sale on Jules Borel but curious which one would suit the best for this watch?

Thanks in advance!

 

I have been using 0.8mm generic gaskets myself, however I also do somewhat doubt the claimed dimensional accuracy of my particular box of gaskets.

 

Get the 0.80mm gasket, it's the one listed by Cousins.

 

Thanks Jim. Btw, the generic seconds hands you recommended me arrived today and it works like a charm.
