Rolex Submariner vs Sea-Dweller: which to buy pre-loved?
The Sea-Dweller is the heavier-duty Submariner: deeper water resistance, a helium escape valve for saturation divers and a larger, thicker case. For most people the Submariner is the more wearable choice; the Sea-Dweller is for those who want the tool-watch spec and don't mind the size.

Rolex Submariner vs Sea-Dweller: questions
Do I need a helium escape valve?
Only saturation divers do; for everyone else it's a mark of the watch's pedigree rather than a feature you'll use.
How much bigger is the Sea-Dweller?
The current 126600 is 43 mm and noticeably thicker than the 41 mm Submariner, so try one on if you can.
Which older references are popular?
Sea-Dweller 16600 and 116600 (40 mm), and Submariner 114060, 116610 and 16610.
