Launched in 1952, the reference 2508 was Patek Philippe’s first time-only model to feature a waterproof Calatrava case. In production until 1960, the generous 35mm Taubert-sourced case featured the same shape and proportions from that of another iconic Patek Philippe, the waterproof chronograph reference 1463. Both watches have a sporty appeal that lends a casual air and have now become beacons for mid-20th century timepiece design with a masculine shape and well-balanced proportions. The model was produced in yellow and rose gold, as well as in stainless steel.

The present watch most notably displays a luminous dial, which is most importantly confirmed by the Patek Philippe Extract from the Archives. Preserved in stunning unmolested condition, the watch displays two deep and crisp hallmarks on the case as well as extremely sharp edges. The watch is, in our opinion, unpolished.

Interestingly, the case back is stamped "F.S. Wade Employee Executive Director Pacific Lighting Gas Co's 1905 - 1963". Indeed, research shows that Mr. Wade worked as the President of the Pacific Lighting Gas Corporation - a company founded in S. Francisco in 1886 and still active today under the name of Sempra Energy (the new name being the result of a series of company mergers). As expected for a Patek Philippe watch delivered to an American buyer at that time, the movement is stamped HOX, denoting it was imported into the USA by the Henry Stern Agency.
