Co-signed by Heuer and Abercrombie & Fitch, the Seafarer chronograph is powered by the manual Valjoux 72 calibre, one of the most respected Swiss chronograph movements of the post-war era. Its distinctive coloured sub-dial sectors were designed to assist with tide indication and nautical timing. This model exemplifies the fusion of high-grade Swiss watchmaking and specialised maritime use in the early 1950s.
