Catalogue Essay
During the 1950s many distinguished watch manufacturers identified a demand for antimagnetic wristwatches. Many of these watches have become so famous and collectable, that one does not need to mention the manufacture's name but only the model name, to brighten any watch aficionado's eyes: Railmaster, Ingenieur, Milgauss and naturally Patek Philippe's Amagnetic!
By definition, Amagnetic watches are tool watches, and consequently cased in stainless steel. Yet, Patek Philippe dared to case a very small number of Amagnetics in yellow gold and even fewer in pink gold. Only seven pink gold examples of the 2570/1 are known, amongst which only three have “Amagnetic” printed on the dial. This watch is furthermore the only one of the three that is accompanied by its original certificate, making the present lot even more appealing and covetable.
Beating inside is the superbly hand finished caliber 12AM400, protected by its original soft iron cover, numbered 697’229 like the case, which can resist magnetic fields up to 450 oersteds. On later versions, as of 1960, this caliber was replaced by a similar movement, caliber 12-AM 400 that featured a Gyromax balance and free sprung regulator.
References 2570 and 2570/1 are very close to each other with only very subtle differences to the crown and the lugs. The crown of the reference 2570 is positioned completely outside the case and has straight lugs whereas the crown of reference 2570/1 is partly set into the case and has elegantly downturned lugs. This watch is not only extremely rare but is also a very attractive and extremely well preserved. It will for sure attract any serious collector’s attention.
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.
