The Rolex GMT-Master II, a watch synonymous with luxury, travel, and precision, is not immune to mechanical malfunctions. While renowned for its robustness and accuracy, instances of the GMT-Master II stopping unexpectedly are reported, causing understandable concern among owners. This article delves into the potential causes behind a halting GMT-Master II, exploring various model iterations and owner experiences to provide a comprehensive understanding of this issue. We will examine several specific models, including the 16710 Pepsi, the 126710BLRO, and the 116710, while referencing discussions from Rolex forums and owner reviews to paint a complete picture.
Understanding the Rolex GMT-Master II Versions and Their Potential Issues:
The Rolex GMT-Master II has undergone several iterations throughout its history, each with its own unique design features and movement. Understanding these differences is crucial when diagnosing potential problems. The variations in movement and materials can influence the watch's susceptibility to malfunctions.
1. Rolex GMT Master II Models and Their Characteristics:
* Early Models (Pre-1980s): These models often featured the caliber 1575 movement. While robust, these older movements can be more prone to issues related to age and wear, including lubrication breakdown and part fatigue. Finding a qualified watchmaker experienced with these older movements is crucial for servicing. Stopping issues in these models often point to a need for a full service and overhaul.
* 16710 (Pepsi GMT): The 16710, particularly the Pepsi bezel variant, holds a special place in the hearts of many collectors. This model, typically equipped with the caliber 3185, offers a robust movement but, like all mechanical watches, is susceptible to issues if not properly maintained. Forum discussions frequently mention the 16710 stopping, often attributed to low power reserve, insufficient lubrication, or impacts. A Rolex GMT 16710 Pepsi review often highlights the watch's longevity with proper care, but neglecting maintenance can lead to problems.
* 116710 (LN and GMT Master II): The 116710, available in black (LN) and other bezel variations, introduced the caliber 3186, a slightly improved movement over the 3185. While generally considered reliable, instances of the 116710 stopping have been reported on forums like Rolex Forums. These instances often highlight the importance of regular servicing to maintain optimal performance.
* 126710BLRO (Pepsi): The current generation Pepsi, the 126710BLRO, boasts the newer caliber 3285 movement. This movement incorporates improvements in efficiency and power reserve, potentially reducing the likelihood of stopping due to low power. However, even with this advanced movement, neglecting maintenance or subjecting the watch to significant shocks can still lead to malfunctions. A Rolex 126710BLRO owners review often praises the improved accuracy and reliability of the 3285, but servicing remains crucial.
* Other Variants: Rolex has released several other GMT-Master II models with variations in bezel materials, dial colors, and case sizes. While the specific movement may differ, the underlying principles of mechanical watch maintenance remain the same. A stopping watch requires professional attention regardless of the specific model.
