What might appear as a typical, vintage two-register Oyster chronograph model, is in fact an example of an important reference that marked a turning point for Rolex in the design of all its chronograph wristwatches. Coinciding with the end of World War II, the launch of this reference 4500 chronograph introduced an all new case style with straighter, more pointed lugs that is until today, still found on all of Rolex’s Oyster models, ranging from the Datejust, to the Day-Date, to the Daytona. Before the war, Rolex’s lugs featured a curved shape that can be described as “Calatrava”-like. In fact, it’s believed that its reference number may have been selected to highlight the year of this historical pivot point for the brand.

The present reference 4500 in 18-karat pink gold is a remarkable example. Accompanied with its guarantee and Rolex presentation box, the watch is presented as found, free from any restorations, and exhibiting gorgeous patina throughout. The multi-scale dial features an eye-catching blue telemeter within the black tachometer scale found along its outer circumference. The case retains its original curves and well-defined lugs, with a pleasing, rainbow color oxidation on the sides of the case illustrating how the watch was sparsely worn.
