Rolex Sea-Dweller 43mm

Since its 50-year reboot in 2017, the 43 mm Sea-Dweller has become the sweet-spot saturation diver: deeper-rated than a Submariner yet slimmer than a Deepsea. It offers a 1,220 m depth rating, a helium-escape valve, and the next-gen Calibre 3235 with 70 h reserve.

Why Choose a 43 mm Sea-Dweller?

• Professional Depth Rating – 1,220 m (4,000 ft) with automatic helium-escape valve for saturation diving.
• Cyclops Convenience – Post-2017 models add the date magnifier absent on older Sea-Dwellers.
• Glidelock + Fliplock Extension – Tool-free 20 mm micro-adjust plus 27 mm dive-suit link.
• Calibre 3235 Performance – Chronergy escapement, Parachrom hairspring, 70 h reserve, -2/+2 s day accuracy.
• Relative Value – Steel 126600 trades ~20 % below retail, offering flagship engineering at entry-level premiums.
