In 1941, Patek Philippe launched the first of its legendary perpetual calendars. The ref. 1526 was made until 1952 and at the time, this reference and the ref. 1518 were the only perpetual calendar wristwatches available on the market. We are looking for a ref. 1526 in either yellow or pink gold, but if you have a stainless steel version, we need to talk as soon as possible!
