Tudor 79260 leather strap replacement options?

[Mr_Pacman]

I've got a Tudor chronograph with the leather strap that is on a Tudor deployant.

The strap is 20mm x 16mm and appears to be a standard strap otherwise. It has holes in the long piece and the short piece looks like it could take a regular tang buckle.

Has anyone found a good aftermarket strap in 20mm x 16mm in calf leather?

I know there are custom options out there, but I was hoping to find something from usual suspects such as Hirsch, Di Model, Rios1931 etc.

Hoping for something in brown but black will work as well.

thanks
