A truly landmark model, reference 2497 was released in 1951.

Launched alongside the famed perpetual calendar chronograph reference 2499, Patek Philippe released this simple perpetual calendar, just as it had released the predecessor reference 1518 alongside the reference 1526. The references 2497 and 2499 were designed with larger diameter cases featuring more robust and elaborate lugs compared with their predecessors. Additionally, a waterproof companion was introduced shortly after the reference 2497, the rare reference 2438/1. Established scholarship tells us that there were a combined total of only 179 total examples made across both references 2497 and 2438/1, with movement numbers spanning from 888’000 to 888’178. Some two thirds of these movements were placed within the reference 2497 over a production span of over 10 years. In fact, Patek Philippe took the challenge of creating a so-called “simple” perpetual calendar (if such a thing is not an oxymoron) to heart, adapting their much-lauded caliber 27 SC (SC for “seconde au centre”) to have a perpetual calendar function, transforming it into the 27 SC Q (Q for “quantième”). The sibling references 2497 and 2438/1 were the world’s first perpetual calendars with center seconds.

The case is virtually identical to the reference 2499, with gracefully fluted lugs and a robust, stepped case. Early examples such as the present lot are further characterized by delicate feuille hands and alternating gold dot and Arabic numeral indices

Fresh to the market, the present watch is a very attractive specimen, featuring crisp fluting to the lugs, it also displays two hallmarks which are deep and crisp beneath the lugs.
