Pre-owned Rolex Submariner ref 126613 (2020). Rolex introduced the 1266XX generation of Submariners back in 2020. While the overall aesthetics are largely the same, from the 60-minute diver’s bezel to the large, easy-to-read hour markers and hands, and reliable Triplock screw-down crown, it also introduced many very notable upgrades. The first is the case, which is now 41mm, compared to the previous 40 mm generation. Rolex also upgraded the movement from the trusty caliber 3135 to the caliber 3235. It was a highly anticipated move as the Crown had already been using the time-and-date movement for other watches for several years prior to the current generation. So, it only made sense to move the Submariner to that caliber as well. It’s more efficient and has a longer 70-hour power reserve, which means you can take this watch off for a few days and it will still read true when you strap it back on. Ref. 126613 is a very desirable Yellow Rolesor model with a sharp black dial and a matching black bezel. Shop Rolex Submariner Collection
