I’ve written about this watch before, picking it as a “grail” even before I bought it. It’s a good example of the “DS” shock proof case from Certina and has good period details. I purchased this at auction (the only bid) with an incorrect modern box and papers.
Dive watches have been in vogue for quite a while, and off-brand vintage divers are really getting hot right now. My Enicar super-compressor has gotten more notice than almost anything else I own, and the segment just keeps getting more interest. This Certina DS-2 is a steal, with bidding starting at just €200, since it’s a nice retro diver with real history and a wearable 37mm case.
