The Rolex GMT-Master II reference 126713GRNR is a 40mm timepiece in Steel and Yellow Gold presented in unworn condition, with a Black Standard dial, Black-Gray Ceramic Standard bezel, Jubilee bracelet, dated circa 2025. Accompanied by its original box and papers for full provenance. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Rolex's 1983 revision to the GMT-Master added a hand you could set on its own, separate from the main time. That is the functional heart of the "II." Around it sits a 40mm Oyster case, a two-tone ceramic bezel, and the Cal. 3285. From the long-serving 16710 to today's 126710-series, each generation has a place. We authenticate in-house so the history checks out. Read the full GMT-Master II buying guide ›
Today Rolex dominates the prestige sports-watch market and functions as much as an asset class as a timepiece. The brand, founded in 1905 by Hans Wilsdorf, pioneered waterproofing, self-winding movements, and date displays from its Geneva manufacture. Our authentication covers the Oyster case, Perpetual movement, and Cyclops lens. Since steel references trade above retail and supply stays tight, expert guidance helps you buy the right piece.
