Bulova 1960 Sea King

Sea King, unknown variant???  Purchased this recently.  Believed it to be a Sea King but I did not see an exact match for the number font on this dial already posted on the site.  After it arrived I looked through the add section more thoroughly and found a 1960 add that appears to match it(partial image above).  The number font in the add matches this dial.  The expansion band in the add also appears to match this one.  No variant ID is mentioned in the add.  Its in nice condition except for a bit of grunge around the spring bars and lug area.  Works very well and has kept accurate time over the last two days.  I love the odd dial font and wafer-thin design.  Couldn't pass it up when I saw it. 

 Any confirmation on the Sea King ID and possible variant would be appreciated.

Thanks!
