Bulova 1971 Sea King

White stainless steel case self-winder that is about 31.2 mm not including crown and lugs.  Silver-white background dial with whale. Large rectangle-shaped indices at the compass points and smaller matching indices at all others.  Linear hour and minute hands with lume, and sweep second hand.  N1 date coded caseback with presentation engraving for 25 years service.  Based on another site ID I believe this is a Sea King FS variant.  Possibly the original band on this one.  

Thanks for any info.
