What are Compressor and Compressor 2 types, and how are they different from the Super-Compressor?
From what I’ve observed regarding the few Compressor type watches that I have seen, and from what I’ve been able to translate from this advertisement, both the Compressor and Compressor 2 types have snap on case backs, and the Compressor 2 may have been a shaped case (i.e. cushion or tonneau), not round. Super Compressors typically used a screw-on case back, excepting the Enicar models which used a bayonet mount caseback.
From what I’ve observed regarding the various Compressor type watches I have seen and what I’ve been able to translate from this advertisement, both the Compressor and Compressor 2 types have snap on case backs. Compressor 2 types use a shaped case (i.e. square, cushion or tonneau), not round. Compressor and Compressor 2 watches while water resistant, are commonly seen in “fashion” watch styles, and while designed to be water resistant are not dive watches.
