Original strap is calfskin but easy dusting and tear off
I order 4 new straps to try
-Delugs (Alligator)
-Visconti Milano (Alligator)
-Camille Fourteen (Calfskin)
-Patek’strap (Alligator)
The winner is Patek, and the rest ranking are accordingly Camille, Visconti , Delugs.
Unfortunately I order all in Navy blue
not different colors as wish to get exact comparisons
