parrott 0 Posted August 14, 2013 I'm curious to know why Rolex Milsub reps come with a Sea Dweller case with a Helium Escape Valve. Why don't they use a 5513 case instead? I would think that the 5513 case would be cheaper so I know they're not doing it to save manufacturing costs. Im confused. Quote MultiQuote Edit Share this post Link to post Share on other sites
