Hi Nicolas,
I'm dreaming about some new watches in Mexico City at the moment... And it is 05:20 am lt here. I must be crazy.
Yes, the Sea Dweller Deep Sea is a tool watch. But if a similar brarelet and bezel is added to a Submariner (300 m), that is in my opinion even a better tool watch.
Sure, it is fine that Rolex is illustrating that their watch can dive to "Titanic". However, no man can dive to depths where a Submariner would start to leak.
I think that the SDDS is a bit heavy and thick even for scuba diving but sure, that's a matter of taste.
Regards,
Kari
PS. All my daughters (15 y, 13 y. and 10 y.) are now certified divers. I will come with them in mid April to Paris to look for ideal diving watches for ladies. I hope Rolex will surprise us all with a Lady Submariner but if not, we could perhaps meet in a small Boutique from where I got my -65 Tribute...
