The Rolex Oyster Perpetual GMT-Master 1570. The very name evokes images of intrepid explorers, seasoned pilots, and a bygone era of unparalleled horological craftsmanship. This vintage timepiece, a predecessor to the modern GMT-Master II, holds a special place in the hearts of collectors and enthusiasts alike. Its enduring appeal stems not only from its historical significance but also from its robust design, impeccable functionality, and the undeniable allure of owning a piece of Rolex history. This article will explore the 1570 in detail, examining its features, its place within the broader Rolex GMT-Master lineage, and its current market value, touching upon related models like the Rolex GMT-Master II and its various iterations.
Understanding the Rolex GMT-Master Time Zone Functionality:
Before delving into the specifics of the 1570, it's crucial to understand the core function that defines the GMT-Master line: the ability to track multiple time zones simultaneously. The GMT-Master was originally conceived in collaboration with Pan Am, the now-defunct airline, to meet the needs of their pilots who frequently traversed the globe. The watch's defining feature is its independently adjustable 24-hour hand, which allows the wearer to track a second time zone alongside the standard hour, minute, and second hands. This is achieved through a bidirectional rotating bezel, graduated in 24 hours, usually with alternating colors (often black and red) to denote day and night. This ingenious system allows for effortless tracking of a second time zone without the need for complex calculations. The 1570, while a precursor to the more sophisticated GMT-Master II, embodies this fundamental functionality with its characteristic elegance and reliability.
The Rolex GMT-Master 1570: A Closer Look:
The 1570, produced in the late 1950s and early 1960s, represents a transitional phase in the GMT-Master's evolution. It bridges the gap between the earlier, simpler references and the more refined models that would follow. While sharing the core GMT functionality, the 1570 boasts several distinct characteristics:
* Caliber 1036: This robust automatic movement powers the 1570, providing accurate timekeeping and the reliable performance expected from a Rolex. The caliber 1036 is known for its durability and its ability to withstand the rigors of daily wear.
* Case Size and Materials: The 1570 typically features a 39mm stainless steel case, a size that has become increasingly desirable in recent years as the market trends towards larger watches. The relatively smaller size of the 1570, however, gives it a vintage charm that appeals to many collectors. The case, like all Rolex Oyster cases, is known for its water resistance and protection against the elements.
* Dial Variations: The dials of the 1570 are highly sought after by collectors. Variations include different fonts, colors, and marker styles. These subtle differences can significantly impact the value of a particular example. The most common dial colors are black and cream, but rarer variations exist, further enhancing the collectibility of the watch.
* Bezel: The 1570's bezel, like its successors, is the key to its GMT functionality. The bidirectional rotating bezel is typically made of aluminum and features the 24-hour graduated scale. The condition of the bezel is a critical factor in determining the value of a 1570, as these bezels are prone to fading and wear over time.
