The Chronomaster Valjoux 23 Big Eye is available in four strap configurations that each express a different aspect of the watch's character. The beads of rice bracelet references the specific bracelet style associated with Nivada Grenchen's vintage models and gives the watch the most period correct integrated appearance. The black racing strap emphasises the motorsport connection of the big eye format. The brown leather with white stitching brings a warm, vintage rally watch aesthetic that sits beautifully against the matte black dial. The rubber tropic strap references the tropical rubber straps common on professional watches of the 1960s and adds a more casual, active wearing character.
