Since my obsession began with buying/researching vintage watches one brand that is an anomaly to me is the aquastar brand. I know it started in the sixties with the famous benthos watch and still exists today in making quartz sailing watches but almost all the watches in between seem to be co branded with makes such as Heuer,Tissot,Duward , JeanRichard and so forth. So, if I buy a Tissot aquastar or a Duward Aquastar am I buying an aquastar rebranded eg,. Duward to sell in Spain or am I buying in this example a Duward .
I noticed that the Duward aquastar 20atm looks almost exactly the same as the JeanRichard aquastar 20 atm.
I have also noticed that the regate watch designed by Aquastar with the lemania 1345 movement was sold under the brands, Aquastar,Tissot,Omega,Heuer and others - very confusing
