Rolex Sea-Dweller Deepsea  employs awe-inspiring watchmaking technologies to allow it to withstand pressures up to 12 800 feet/3 900 meters below the ocean's surface. In addition to sporting Rolex's famous Triplock screw-down crown with three hermetically-sealed zones it is also furnished with a Helium Escape Valve Ring Lock System a thicker 5mm sapphire crystal and a flexible titanium case back. As a result this watch is quite robust measuring 44mm in diameter. At the same time it maintains Rolex's signature elegance with a lustrous black ceramic bezel and matching black dial with white gold-trimmed hour markers and hands. Most collectors will never need to take their Rolex thousands of feet into the ocean. Still the sheer ingenuity and watchmaking prowess required to accomplish such a feat is enough to win over even the most discerning collectors.
