Rolex. A fine and rare 18K gold chronograph wristwatch with champagne dial and fancy lugs

Reference 4313 was launched in the 1940s and is characterized by the large teardrop-shaped lugs mounted onto the bezel, a feature found exclusively in this unusual model. The atypical dial is distinguished by the omission of any of the technical scales (tachometre, telemetre or pulsometre) that one would usually expect on this reference. Consequently the entire layout could be modified, moving the numerals further to the edge and hence increasing the readability. Interestingly due to the different dial proportions, the watch, already one of Rolex's largest 1940s chronographs, appears even larger.
