Launched in 2005, the ref. 5250 in white gold was the first Advanced Research limited edition model of the series. Revolution in design, Patek Philippe developed the ground-breaking silicon-based escape wheel for a Swiss lever escapement with and annual calendar movement, the caliber 315 S IRM QA LU SI. The dedicated Advanced Research department was created to focus exclusively on exploring and developing new technologies and materials; it underlines the company’s continued commitment to technological advances in horology.
Produced in a limited edition of 100 examples only with a slick monochromatic appeal, the present ref. 5250 is a great addition to the collector of the Advanced research series.
Since its founding in 1839, this famous Geneva-based firm has been surprising its clientele with superbly crafted timepieces fitted with watchmaking's most prestigious complications. Traditional and conservative designs are found across Patek Philippe's watches made throughout their history — the utmost in understated elegance.
Well-known for the Graves Supercomplication — a highly complicated pocket watch that was the world’s most complicated watch for 50 years — this family-owned brand has earned a reputation of excellence around the world. Patek's complicated vintage watches hold the highest number of world records for results achieved at auction compared with any other brand. For collectors, key models include the reference 1518, the world's first serially produced perpetual calendar chronograph, and its successor, the reference 2499. Other famous models include perpetual calendars such as the ref. 1526, ref. 3448 and 3450, chronographs such as the reference 130, 530 and 1463, as well as reference 1436 and 1563 split seconds chronographs. Patek is also well-known for their classically styled, time-only "Calatrava" dress watches, and the "Nautilus," an iconic luxury sports watch first introduced in 1976 as the reference 3700 that is still in production today.
