For the Navitimer AB0121A21B1A1 with a blue dial, the most suitable straps include midnight blue or black alligator for a formal look, tobacco vegetable-tanned calfskin for a vintage aviation aesthetic, or bordeaux shell cordovan for a refined pairing. A brushed steel deployant clasp is the most coherent closure choice given the watch's technical character.
