Longines made a variety of bold, colorful sport watches from the late 1960s to early 1970s. The present example is a Conquest diver, featuring a Super Compressor case by EPSA. The Super Compressor has a proprietary spring in the caseback that tightens as it is exposed to greater pressure. Another characteristic of the Super Compressor is the internal rotating bezel actuated by the top crown. The 6651 caliber is an in-house high-beat caliber.
