Cartier Tank Solo Ladies Small

[cometome]

I searched everywhere but I can not find the dimensions of a strap for the tank solo small ladies size (25mm x31mm). Does anyone know what the strap size would be or where I could get some?

It seems the strap doesn't have holes in it either making it harder to find a correct fitting one?

All sources I can see say band width is 20mm:
