The most suitable straps for the Breitling Colt A7438911/BD82/238S/A16S.1 are: vegetable-tanned calf leather for daily wear with natural patina development, matte alligator for formal pairings, technical nylon NATO for faithfulness to the instrument watch heritage, and vulcanised rubber for sporting use.
