The Rolex GMT-Master II, a watch synonymous with travel and adventure, has captivated watch enthusiasts for decades. Its instantly recognizable bezel, versatile functionality, and robust construction have cemented its place as a horological icon. However, beyond its aesthetic appeal and legendary status lies a crucial question: what is the accuracy of the Rolex GMT-Master II? This exploration will delve into the precision of this celebrated timepiece across various models, examining owner experiences and exploring the factors contributing to its overall timekeeping performance.
While Rolex boasts that all its watches are chronometers, certified by COSC (Contrôle Officiel Suisse des Chronomètres), understanding the real-world accuracy requires examining individual models and considering factors beyond the initial certification. COSC certification tests a movement’s accuracy in five positions and at different temperatures, guaranteeing a daily rate of -4/+6 seconds. However, this is a laboratory setting; real-world performance can be affected by numerous variables.
