PATEK PHILIPPE. A RARE 18K GOLD WRISTWATCH WITH SWEEP CENTRE SECONDS AND RADIUM INDEXES

Considered by many to be among the pinnacles of Patek Philippe's mid-20th century design, the reference 2508 distinguishes itself from its "time-only" brethren with a uniquely balanced case design. The 2508 was Patek Philippe's first foray into waterproof case designs for non-complicated wristwatches. Previously, the only waterproof wristwatch was the reference 1463 chronograph, from which the 2508 would borrow the entirety of its form. The downturned lugs, perfectly proportioned dial, and screw-back case profile produce a masculine and most pleasing wrist presence not found in other Calatravas. The 2508 could be considered a successor to the legendary reference 570, though with a "sportier" feel, and forerunner to "Amagnetic" references due to its "double case-back" design.
Inside the 2508 beats the legendary 27SC, covered by a metal dust cap to keep moisture and magnetism at bay - a trait found predominantly in "tool" watches, making this reference a unique offering in Patek Philippe's lineage.
