I picked up this Jean Richard Aquastar diver and O&W chrono. I assume the chrono has a Valjoux of some kind. Will post a photo of the movement. Both are running, though the chrono pushers do not work. I think the Aquastar is an earlier model of that line, but still doing research. I've found a few with that bezel and those hands, but it's that combo appears to be less common. I plan to keep the diver and might sell the chrono to pay for diver overhaul/bracelet.
