Nice clean looking watch plains
I'm not sure this watch was properly vetted and I'm not sure it's a Sea King. What ad was used to ID? Like Jerin, I don't see it either.
ad Dated 1961

the Case lugs of the subject are coming up a bit short.
Sorry, I don't see this watch in that ad. This ad appears to be introducing new watches for 1961. Unknown - moving to reopen record.
although an exact match is not shown in the 1961ad, the subject has the characteristics of the 'SEA KING'.
The ad shows 6 Models but then states there were 12 (new in addition to theire predecessors?)
OT has a 1959 'SEA KING' in the database, Case diameter and design comparisons could help.
Possibly a Sea King, but no matches found.
Unknown.
Unknown after checking all the adverts.
Bummer, I have one too dated 1960 N0. Has the whale and the words Sea King Automatic on the dial. Haven't found an ad for it either.

N0 is 1970 John. Why not post it?
Just haven't time. I have several to post and am planning on doing it later this week. I recently bought a Rubiyat and a Lady Maxim and am awaiting the Lady Maxim to post them as well. I have been working at my part time job a little more than usual lately so I have been cutting back on the watch work.
