Bulova 1969 Sea King "EX"
1969 Bulova Sea King 'EX'
All stainless steel case and caseback, dated M9; case number 2920; dial has black lettering with luminous hands and dots, black second hand; movement is a manual-wind 11BLC 17-jewel dated M9.
The case is unusual to me, as it does not accept spring bars. The band fits in an opening and is held in by the overlay of the bezel and caseback.
