The Rolex GMT-Master, a watch synonymous with aviation and global travel, has a rich and storied history. Within that history, the reference 16700 holds a special place, representing a significant evolution in the model's design and functionality. This article delves into the heart of the 16700 – its Caliber 3175 movement – exploring its specifications, performance, and the factors that contribute to the continued desirability and value of this iconic timepiece. We'll also address key aspects surrounding the 16700, including its price, condition assessment, and its position within the broader context of Rolex GMT-Master history.
The Caliber 3175: A Workhorse of Precision
The Rolex GMT-Master 16700 is powered by the self-winding Caliber 3175 movement. This robust and reliable movement is a testament to Rolex's commitment to horological excellence. Unlike its predecessor, the Caliber 3075 found in the reference 1675, the 3175 boasts several key improvements. These enhancements contribute significantly to the watch's accuracy, durability, and overall performance.
Key features of the Caliber 3175 include:
* Self-winding mechanism: The 3175 utilizes a highly efficient rotor system, ensuring consistent winding through the natural motion of the wearer's wrist. This eliminates the need for manual winding in most instances, providing continuous power reserve.
* High precision: Rolex movements are renowned for their accuracy, and the 3175 is no exception. It's designed to meet Rolex's rigorous standards, typically achieving chronometer-level performance (COSC certification, although not always explicitly stated on the dial). This means it maintains exceptional timekeeping within specified tolerances.
* Shock resistance: The movement incorporates robust construction and shock-absorbing components to withstand the impacts and vibrations of daily wear. This resilience is crucial for a tool watch like the GMT-Master, which was originally designed for pilots.
* Date function: In addition to the timekeeping functions, the 3175 also includes a date display window at the 3 o'clock position. This practical addition enhances the watch's everyday usability.
* Independent 24-hour hand: The hallmark of the GMT-Master is its ability to display two time zones simultaneously. The 3175 movement facilitates this with an independently adjustable 24-hour hand, crucial for tracking a second time zone.
Comparing the 16700 and its Successor, the 16710
The Rolex GMT-Master II reference 16710, introduced later, utilizes the Caliber 3185 movement. While both movements share similarities in their fundamental design, the 3185 offers several advancements:
* Quickset date: The 3185 incorporates a quickset date function, allowing for easier adjustment of the date. The 3175 requires cycling through the dates using the crown.
* Improved lubrication: The 3185 benefits from refinements in lubrication, leading to potentially smoother operation and extended service intervals.
