The Rolex GMT-Master 1675, affectionately nicknamed "Samtkissen" (German for "velvet cushion") due to its pillow-like case shape, holds a special place in the hearts of watch enthusiasts. This iconic timepiece, produced from the mid-1950s to the early 1980s, represents a pivotal moment in Rolex's history and a defining era in the evolution of the GMT functionality. Its rugged construction, distinctive aesthetic, and fascinating history make it a highly sought-after collectible, driving up prices significantly in the vintage watch market. This article will delve into the intricacies of the Rolex GMT-Master 1675, focusing on its movement variations, its evolution, its desirability, and its impact on the world of horology.
The Heart of the Beast: Movement Variations in the Rolex GMT-Master 1675
One of the key aspects that contributes to the complexity and intrigue surrounding the Rolex GMT-Master 1675 is the variation in its movements. Unlike many Rolex models that feature a single, consistent calibre throughout their production run, the 1675 utilized two distinct movements: the Calibre 1575 and the Calibre 1565. Understanding these differences is crucial to appreciating the nuances of individual 1675 examples.
The Calibre 1575, the earlier of the two, is characterized by its robust construction and reliable performance. It's a manually wound movement, reflecting the technology of its era, and it offered a power reserve of approximately 48 hours. This movement, with its relatively simple design, laid the foundation for the later, more refined Calibre 1565. Finding a 1675 with a Calibre 1575 is generally considered more desirable by collectors due to its historical significance and the perceived robustness of its construction.
The Calibre 1565, introduced later in the 1675's production run, represented a significant upgrade. While still a manually wound movement, the 1565 incorporated several improvements over its predecessor, leading to enhanced accuracy and reliability. These improvements often involved subtle adjustments to the escapement and balance wheel, resulting in a smoother, more precise timekeeping experience. The 1565 also boasts a slightly longer power reserve than the 1575.
Distinguishing between the Calibre 1575 and 1565 requires a keen eye and often involves scrutinizing the movement through the caseback (if transparent) or by accessing the movement through professional servicing. The subtle differences in the bridges, engravings, and other components can provide clues to identifying the specific calibre. However, it's often advisable to consult with a knowledgeable watchmaker or Rolex expert for definitive identification. This distinction significantly impacts the value of a particular 1675, with Calibre 1575 examples often commanding a premium due to their rarity and historical significance.
