In this case "Seamaster Caseback Emblem" would currently come up with nothing useful.

"Introduced in 1956, the seahorse logo was engraved on the caseback of the Seamaster and the Railmaster, which was primarily a water-resistant watch with specific protection against magnetic exposure.

So, with the 1957 launch of the trilogy collection in (consisting of the Seamaster, Speedmaster, and Railmaster), Omega issued a line of professional watches engraved with the new mythical seahorse logo.
The emblem was officially adopted in 1958 to signify the Seamaster's water-resistant capabilities

Yes, here is the history:

Yeah it's hard to decipher. Seems to say that they engraved the first caseacks with the seahorse in 56, didn't sell any until 57, and made it official in 58.
