The Rolex GMT-Master II reference JUB-ST-S-GMT is a 15.5mm timepiece in Steel presented in unworn condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
The line runs only at 40mm, which keeps the buying decision focused on reference, bezel, and condition. Box-and-papers completeness, bracelet stretch, and service history each move resale pricing in real ways. Polished cases and swapped bracelets should be reflected in the price, not hidden in it. That is the standard our desk applies, and we explain every finding so you can decide with confidence. Read the full GMT-Master II buying guide ›
Hans Wilsdorf founded Rolex in 1905, and the Geneva manufacture has since become the benchmark against which most mechanical watches are judged. Its engineers pioneered waterproofing, self-winding movements, and date displays, building a reputation for precision and durability. Before you buy, our desk verifies the Oyster case, the Perpetual movement, and the Cyclops lens. With supply trailing demand, steel sports references often trade above retail, so confirmed authentication matters. Browse all Rolex ›
