Thank you for posting your watch.  Based on the N0 date code this is a 1970 model.   Found a match in the 1970 Linebook BAWD#0174.   This is a 1970 Bulova Sea King "EY".  Please confirm the date code on the movement is an M not an N.   M1 is early for this model.  Note the whale was used sporadically by Bulova.

Model year updated to 1970 as per the 'N0' date stamp on the case.

I suspect the date code on the movement is an N1 not M1.   The 11BLAC was not available in 1961.
