Bulova 1969 Sea King

Here's one I have never seen before. Stainless with a silver dial that has square black inserts in the indices. Lume dots and hands. Came to me represented as freshly serviced - keeping time within a minute and a half a day. It took a while to find, but is represented in 1969Linebook170 as

Sea King "EQ" - a first for the database

Interesting note: subject watch has a whale on the dial not seen in the linebook.
