Catalogue Note

Manufactured for just a few years between 1958 and 1963, reference 2438-1 was the first water-resistant type perpetual calendar wristwatch produced in series by any company. Manufactured at the same time as the reference 2497 snap-back, total production of the ref.2497 and 2438-1 combined was just 179 pieces. Patek Philippe used the case maker Wenger, one of the finest and most reputable master case makers in Geneva to make the ref.2438 case. Of course the 2438 differs from the ref.2497 as the former has a water-resistant-type screw-down back and a slightly different size, 37mm instead of 37.8mm.

The movement issued from the in-house 12'''-27SC (27mm, 12 lines) stamped with "HOX" confirming the delivery to the Patek Philippe American agent, the calibre 27SCQ was equipped with the Victorin Piguet under dial perpetual calendar cam modification. The letter 'Q', for quantième, would be added to the calibre name to denote the perpetual complication. Victorin Piguet was a master watchmaking house based in Le Sentier, Switzerland. They had a very long and trusted relationship with Patek Philippe enhancing their perpetual calendar movements and designing unusual complications, such as split second and single-button chronographs.
