Greetings,

I have a 1963 Rolex 6426 which I need to change the crystal.

I was told that I need a Tropic 25-12 crystal but this one seem higher and more of a square shape. The original one seem more domed and flat.

I'v seen pictures of tropic 15 crystals that are sold for tudor 7960 who look like the original one but dont know if this will fit.

Anyone knows which crystal was used or can be used on a 60s 6426?

Your help is greatly appreciated,

Alex
