With Patek Philippe Extract from the Archives confirming production of the present watch in 1937 and its subsequent sale on 6 June 1938.
Reference 492 was in production from 1936 until the late 1940s. It is thought that the present watch is one of only four examples of this reference in stainless steel to have survived to date.
The modern, yet typical Art Deco style case was designed to fit around the wrist and is also called "Railway" because of its aerodynamic look and the stepped sides. With its impressive overall length of 44 mm., it is thought to be one of Patek Philippe's longest rectangular wristwatches in stainless steel made to date.
The highly elegant design of reference 492 served as inspiration for the creation of reference 5105, the limited edition in platinum made to commemorate the reopening of Patek Philippe's Salons in Geneva in 2006.
