The Rolex GMT-Master II, a watch synonymous with travel and adventure, has undergone several significant evolutions throughout its history. One key transition point lies in the movement upgrade from the Caliber 3185 to the Caliber 3186. This seemingly minor change, however, marked a subtle yet significant shift in the aesthetics and performance of the GMT-Master II, particularly influencing models featuring the coveted "stick" dial configuration. This article will delve into the nuances of the Rolex GMT-Master II equipped with the Caliber 3186 movement, exploring its design elements, comparing it to its predecessor and successor movements, and examining the specific characteristics of the stick dial variations.
The Caliber 3186: A Refinement of the Legacy
Before diving into the specifics of the 3186, it's crucial to understand its context. The Caliber 3185, a robust and reliable movement, served as the heart of many GMT-Master II references for years. However, Rolex, ever committed to continuous improvement, developed the Caliber 3186 as a successor, incorporating several refinements. While not a radical overhaul, these subtle enhancements contributed to improved accuracy, reliability, and, some argue, a more aesthetically pleasing presentation.
The exact details of the internal changes between the 3185 and 3186 remain closely guarded by Rolex. However, anecdotal evidence and comparisons by watchmakers suggest improvements in the efficiency of the escapement and potentially in the overall lubrication and construction of the movement. These improvements translate into enhanced chronometric performance, leading to a slightly increased power reserve and potentially even greater accuracy over time. The focus was clearly on refinement, building upon the already excellent foundation of the 3185 rather than a complete redesign.
One visible change, although arguably subjective, lies in the presentation. The movement itself, while largely similar in architecture, might show minor differences in finishing details. However, the more noticeable external change often associated with the 3186's introduction is the subtle shift in the rehaut. The rehaut, that often-overlooked ring of text between the dial and the crystal, is where Rolex inscribes its name and other markings. In models featuring the 3186, some enthusiasts believe the rehaut's printing and overall appearance contributes to a more modern aesthetic, cleaner and more refined than its predecessor. This is a point of contention, however, with some preferring the slightly more vintage feel of the 3185 rehaut.
GMT-Master II 3186 Stick: A Dial Design Distinction
The introduction of the Caliber 3186 coincided with, or shortly followed, the continued popularity of the GMT-Master II with stick markers on the dial. This dial configuration, often referred to as the "stick dial," presents a minimalist and elegant design, eschewing the more ornate baton or rectangular indices found on other GMT-Master II variations. The clean lines of the stick markers perfectly complement the overall aesthetic of the watch, creating a sophisticated and timeless look.
The GMT-Master II 3186 stick dial is highly sought after by collectors and enthusiasts. Its understated elegance, combined with the improved performance of the 3186 movement, makes it a highly desirable piece. The combination of the clean dial and the refined movement creates a watch that is both visually appealing and mechanically impressive. The simplicity of the stick dial allows the focus to remain on the functionality and the craftsmanship of the watch itself.
