Rolex 3132 Movement Review:
The Rolex 3132 is a significant advancement, primarily due to its inclusion of a GMT complication. This allows the wearer to track a second time zone independently of the main time display. This is achieved through a independently adjustable 24-hour hand, often distinguished by a different color or style. Reviews consistently praise the 3132 for its reliability, accuracy, and smooth operation. The added GMT function adds considerable versatility without compromising the inherent robustness of the movement. The movement’s reliability stems from Rolex’s rigorous testing and quality control procedures. Owners often report exceptional accuracy within the COSC (Contrôle Officiel Suisse des Chronomètres) certified standards, meaning it maintains a high degree of precision. The aesthetic appeal of the movement, visible through the caseback in certain models, is another point of admiration. The intricate finishing, including perlage and Côtes de Genève, reflects Rolex's dedication to horological excellence. However, the added complexity of the GMT function might slightly increase the cost of servicing compared to the simpler 3131.
