Notes

Ref. 62400Was introduced in 1965 and was the first Cosmograph model with screweddownpushers and therefore signed "Oyster" on the dial. Only produced instainless steel in very few examples until 1969. It was published in the Rolexcatalogue for the Italian market in 1966. We may consider it as the prototypefor the references 6263 - 6265.
