Unique number 023. Three distinctive lines of red print on the dial identify this as a very exciting Pro-Hunter. Fifty years ago, the original Rolex Deep Sea Special plumbed the planet's deepest ocean trench. Now, commissioned by the owner of one of these very rare old experimental Rolex watches, Pro-Hunter's Deepsea Triple Red reflects the best technical qualities of the day: tough black Diamond-Like Carbon coating, helium release valve, very high pressure-resistance, domed sapphire glass, "Glidelock" clasp, and of course, only 100 numbered pieces! Brand-new, supplied with original manufacturer's box and certificate, and two-year Pro-Hunter guarantee.
