I'm sure there are plenty of scuba divers that own SubC's but there are a lot of people who don't scuba but play plenty of other water sports and hang by water. This is what I like about modern Rolex's as I think you can swim (and shower) with just about all of them.
Who were particularly attracted to Rolex's non-diver watches because of your confidence for them to handle water in most situations but deep diving?
