The Sea Hawk was originally launched in the 1940’s. Given it’s name, it was describing the fact that the line of watches would have some sort of water resistance. The Sea Hawks of this era were military style watches that had manual wind movements. Going into the 1950’s, Girard Perregaux began experimenting with other designs for the line of watches. They wouldn’t be described as dress watches, but straddled between dress and military.
The 1960’s is when the brand really changed the overall feel of the Sea Hawk. Instead of using military styling for their pieces, the Sea Hawk became more of a dress watch - mainly steel pieces with some gold plated watches. The watches were typically time-only in complication and used manual wind movements. The watches also increased in size to the 34mm mark.
