Though seems a simple and dumb question, but I over and over again find members asking this question, not in this forum, but also other watch forums, so here to the favor of some newbie members who just come to watches, I would like to post a thread about the series number in this regards, certainly, if you already know, click the back button on your page. Ok, no more nonsense, right into the topic.
Starting in 2003, Rolex began to engrave serial numbers along with the word “Rolex” on the inside wall of the case (also known as the rehault). Sport models like the Submariner 16610 received the engraved rehault in 2006/2007 during the late Z serial number issues. And in 2010, beginning with the late V serial numbers, Rolex serial numbers began to disappear from the 6 o’clock lug, and on current models the serial number can only be found on the rehault. Below is a picture of an engraved rehault with the serial number at the 6 o’clock.
however, Rolex serial numbers can be found at the 6 o’clock lug when the bracelet is removed, as seen in my photo below.
