Seven Seas was a registered trademark used for dials on watches, clocks & chronometers - filed on the 21st February 1939 by Robert L. Hunter of The Nautical Clock Co. The Seven Seas pocket watch had been in production and updated for several decades since it first appeared in 1938. They were marketed by Nautical Clock Co. of Norfolk VA USA and powered by an E.
