The 1675: Heart of the 1970 GMT-Master
The 1970 GMT-Master was primarily produced as the reference 1675, a model that solidified the GMT-Master's position as a quintessential tool watch. Unlike its predecessors, the 1675 featured a significantly improved movement, the caliber 1575, which offered increased reliability and accuracy. This movement is a crucial factor in determining the value and desirability of a 1970 example. The 1575 provided the crucial independent hour hand, allowing the wearer to track a second time zone simultaneously with local time, a feature that defined the GMT-Master's functionality.
The case of the 1675 was typically constructed from stainless steel, offering robustness and durability. Its size, while smaller than modern GMT-Masters, remains perfectly wearable for most wrists. The crown, signed with the Rolex crown logo, is a hallmark of authenticity and quality. Careful examination of the crown and its operation is crucial when assessing a vintage piece for potential servicing needs. The caseback, usually engraved with the reference number and other markings, provides further clues to the watch's authenticity and history.
The Iconic Bezel: A Defining Feature of the Rolex GMT 1675 Bezel
The bezel of the 1970 Rolex GMT-Master 1675 is arguably its most striking feature. While variations exist, the most sought-after are the "Pepsi" bezels, featuring alternating red and blue 24-hour graduations. These bezels were not only functional, allowing the wearer to quickly read a second time zone, but also aesthetically pleasing, adding a pop of color to the otherwise classic design. The condition of the bezel is a significant factor in determining the value of a 1970 GMT-Master. Faded, cracked, or replaced bezels can significantly detract from the watch's value, while original, well-preserved bezels command a premium. The material of the bezel insert, often bakelite in earlier examples, is also a key consideration for collectors. Bakelite bezels are known for their unique aging characteristics, with some developing a beautiful patina over time, while others may fade or become brittle.
