A dive watch should be substantial. Don't go minimalist. Minimalist looks and feels fragile. Start with the popular high end watches and work backwards. Think submariner meets Eco with more actual diving application.
Also I'd not worry about price tag. If you build a quality product you'll sell it at a fair price (keeping in mind that you don't likely have a big brand to back you, but a $1500-$2500 functional and fashionable dive watch is reasonable IMO).
