This pocket watch, reference 5215, is the first-ever anti-magnetic (40,000 A/m) and water-resistant (30 meters) pocket watch. It is part of the Ingenieur series and only 200 copies were ever made from 1983 to 1996. The model was produced with four different dials, and the one we have is known as the Millimeterpapier or graph paper by collectors. Due to its limited production and unique features, reference 5215 is highly sought after by collectors.
