Looks great on my black chronos, especially the panda dial Hamilton chronomaster and a speedie moonwatch. The leather is very stiff but is starting to soften, it feels very high quality and well constructed.
I'm very selective with replacement parts on my personal equipment. This strap actually complements very nicely my watch. Superb product.
This strap, with its double tangs and calfskin color is very smart-looking on "Vintage" watches and all others that would benefit from its gorgeous color. The leather is durble and supple; a real winner.
Superior quality but be warned that constant open and closing will eventually tear failure in the material since the double pin creates a weak point.
