I think they look like DOXA, one of the brand that supply to Jacques Cousteau in the 60s/70s when he was filming a lot of scuba diving TV program. Back in those days there wasn't that many good dive watches and DOXA was one of the main one use by Jacques Cousteau diving expedition. It has a cult status however the brand has had some difficulties like most swiss watch company in the late 70s and ceased operation in 1980. It was revive recently.
My guess is Aquadive is piggybacking on the DOXA SUB300T deign to win some of their old fans. They both look strikingly similar.
Check out DOXA SUB300T if you like this kind of design. The orange dial is striking.

I have never tried a Micro brand before. Am interested in a watch from the brand Aquadive. Aside from the main website, where else would one get reviews on the watch?
