Dive watches for diving
There is a class of diving watches (out there) that have novel accoutrements and the Blancpain people have just released the X fathoms.
I thing that it is a reasonable assumption that these 'divers' are not intended for real(pragmatic) use in today's diving world.
They are, as with all mechanical watches, further exploration into the art and imagination of horology.
I think that it assumed that luxury watches will live up to the demands of a harsh environment (and most of them do) but we don't (or at least I don't) buy them for that purpose.
We like the idea of them, the imagination, the design, the workmanship, the engineering and the good fortune to be able to buy them!
Of course we expect to be able to wear them in the depths of the ocean or at the peaks of the Himalayas!
They must live up to the claims by the manufacturers.
