When the budget opens up
Above €10,000 the dive-watch market shifts: the question stops being 'does it have a real chronometer movement' (yes, all of these do) and starts being 'how is the movement finished, who built it, and what's the bracelet engineering'. The Rolex Submariner sits at the top because its case, bracelet, and Cal. 3235 are individually all best-of-their-kind.
We've included the Aquanaut here even though it's not strictly a dive watch (rounded-octagon case, water-resistant but not certification-spec). At ~€32k it's one of the watches that defines the modern luxury water-resistant sport-watch market.
