Specs Year/era: 1980s Reference: 7177 Serial: 3757 Dimensions: 40mm wide. Movement: Lemania cal. 5100. Briefing The Orfina Military chronographs represent the most utilitarian expression of the early Porsche Design era. Produced for military use, the ref. 7177 is defined by its matte black PVD-coated case, tritium dial, fixed bezel, and the robust Lemania 5100 chronograph movement-long favored in military procurement for its central-minutes layout, shock resistance, and reliability under demanding conditions. These watches gained further cultural recognition when U.S. Navy aviators wore similar PVD Orfina models and were later adopted into popular media associated with "Top Gun." This example's military-engraved caseback confirms its intended service role, adding meaningful historical significance to an already purpose-built design. It has remained in lovely vintage condition with a very well preserved dial/hands. The case/bracelet have honest wear suggesting potential use in the field. Included is a service receipt from Superior Watch (Authorized Porsche Design service center).
