I've been shopping around for a slightly dressier strap for my Omega Speedmaster, the kind of strap that would look nice on a Heuer chrono.
I found a nice British shop called Equus Leather that makes English Bridle Leather straps.
Very nice work, custom made, and a nice alternative to an Alligator or Crocodile strap.
But at a very serious price, too.
A black leather strap, 20 mm tapering to 18, with a Hirsch buckle is almost $250 and the wait is more than a month.

Hmmm. I did a little googling, and found a very nice alternative at a much more reasonable price.
Fluco makes an English Bridle Leather strap too. I got mine today and I'm very pleased. It's plain but elegant and well-suited the busy dial of a chrono.
It not be *quite* as nice as the Equus, but it's also $36 and you can have one in four days.
