Rolex Sea-Dweller 126600 ‘Red Text’ | Saturation Dive Watch

The Original Saturation Dive Watch

Born in the late 1960s alongside the rise of commercial saturation diving, the Rolex Sea-Dweller was engineered in collaboration with pioneering firms like COMEX. Its breakthrough Helium Escape Valve solved the problem of trapped gas during decompression—preserving both crystal and accuracy when the pressure was at its most unforgiving.

The Curator’s Insight

The HEV remains a beautifully simple answer to a complex problem—an elegant valve that unlocked true saturation capability and cemented the Sea-Dweller’s status as a no-compromise professional instrument.
