The Seamaster-Railmaster made for the Pakistani Air Force (PAF). According to legend, whoever was in charge of choosing a watch for the Air Force wasn’t thrilled with Railmaster on the dial (for whatever reason), and wanted the Seamaster dial. Therefore, PAF Railmasters have Seamaster dials, while everything else is Railmaster. This very rare model is accompanied by an Omega extract from the archives.
