The story

The '666' Sea-Dweller: first sapphire SD, first 1,220m rating, and an eleven-year run. Early matte dials are the chase.

Vintage tool Rolex with a devil's nickname and genuine scarcity: collectors cannot resist the combination.

The 'Triple Six' doubled the Sea-Dweller's rating to 1,220 meters, introduced the sapphire crystal to the line, and got its nickname from a reference number that unsettled superstitious buyers, which only helped the legend.

Early matte-dial examples (1978 to roughly 1981) are the collector spec and have pulled away from the later gloss dials. It remains cheaper than the equivalent-era Submariner despite being rarer and more capable: the Sea-Dweller discount, eternally.

Our verdict: The vintage diver with momentum. Matte dial, unpolished case, or walk away.
