An elegant watch designed for those who travel extensively, allowing the traveller to change easily from one time zone to another. In 1958 Patek Philippe introduced reference 2597 with novelty calibre 12-400 HS (for heures sautantes or jumping hours) to the public. It was produced in two versions: the first version such as this example has two pushers on the left side of the case to independently adjust the hour hand backwards/forwards. The second version is fitted with an additional hour hand. Another version of the same system was used in Patek Philippe’s World Time Chronograph reference 5930G, which came on the market in 2016.

Dr. Isidor Schwaner Ravdin (1894-1972)
Ravdin was constantly at the forefront of medical activity, he played a pivotal role in medical leadership throughout the 20th century. He wrote and spoke prolifically, and his wide reputation, ambitious workload and expertise made him the recipient of hundreds of awards, honorary degrees, honorary fellowships and citations. He was decorated by the University, the Military, the Government, foreign governments, major universities and private institutions. In 1957 Ravdin received the prestigious Philadelphia Award, the highest honor the city could bestow for his lifelong contributions to the city.
Ravdin was considered a giant of his own time. He was able to take on numerous responsibilities at once and approach them all with expertise, efficiency and devotion. In his typically direct manner Ravdin said of his life, Each day is a full day but a rewarding one. His legacy to the University of Pennsylvania lives on physically in the Ravdin Institute, but he also lent something more. His colleague Sidney Farber, in the October 1964 issue of Surgery, expressed it best when he described the Ravdinian form -- the idea that the surgeon must be a physician and something more. As Ravdin said so often of others, he was a tower of strength to the University and to the wider world of medicine.
