Your guide to Rolex model numbers

Rolex also engraves a 4-6 digit model number on each and every watch it produces. This marking can be found by locating the area between the lugs on the side of the case, above 12 o’clock. The Rolex model numbers tells a watch collector the type, bezel, and material of the watch.

Suppose you see 16234. This Rolex model number tells you that the watch is a Datejust, the bezel is fluted, and that the watch is made of Stainless 18K White Gold. By using the information below, you too can identify your own Rolex and determine its market value.
