A little tip for those who have the new Carrera Chronograph and want to upgrade to an original leather strap with matching buckle or deployant clasp. The legendary Carrera model from the sixties was often recognized for the nice, perforated leather strap. As far as I know, no rep dealer have a leather strap option for the Carrera Chrono.
The FC6205 leather strap for the current Carrera Chrono has special curved ends, to have a snug fit to the case.
This guy has a great selection of TH straps and buckles. Prices might be a bit steep, 85-100 USD.

I wondered if this should have been posted in the sales section, but I am not the seller, and assumes this has general interest.
