History of the Rolex GMT-Master 16700: Rolex Gmt Master 16700

The Rolex GMT-Master, a legendary watch renowned for its dual-time functionality, has a rich history dating back to the early 1950s. Its evolution over the decades reflects the changing needs of pilots and travelers, leading to the development of the iconic 16700 model.

Origins and Evolution of the GMT-Master

The GMT-Master was born from a collaboration between Rolex and Pan Am, a leading airline at the time. In the 1950s, Pan Am pilots needed a watch that could display two time zones simultaneously, simplifying navigation and scheduling across international flights. Rolex responded by introducing the first GMT-Master in 1954, featuring a unique 24-hour hand that allowed pilots to track a second time zone independently.

The early GMT-Master models, such as the reference 6542, were characterized by their Bakelite bezels and a fixed 24-hour hand. These models were designed for pilots and were often used in conjunction with flight computers. The 1960s saw the introduction of the reference 1675, which featured a rotatable bezel with a 24-hour scale, allowing pilots to easily set and track a second time zone. This innovative feature significantly enhanced the watch’s functionality, making it even more popular among pilots.

The GMT-Master 16700: Design Improvements and Features, Rolex gmt master 16700

The GMT-Master 16700, introduced in 1989, represented a significant evolution of the GMT-Master line. This model incorporated several design improvements and features that enhanced its durability, accuracy, and overall performance.

Improved Movement and Accuracy

The 16700 was powered by the Rolex caliber 3185, a self-winding mechanical movement with a 48-hour power reserve. This movement featured a more efficient winding system and improved shock resistance, making it more reliable and accurate than previous models. The caliber 3185 also incorporated a larger balance wheel, which contributed to the watch’s enhanced accuracy and stability.

Enhanced Durability and Water Resistance

The 16700 featured a larger and more robust case, which enhanced the watch’s durability and water resistance. The case was also redesigned to accommodate the new movement and provide better protection for the internal components. The watch was water-resistant to 100 meters (330 feet), making it suitable for everyday wear and even recreational diving.

Improved Bezel and Functionality

The 16700 featured a new, more robust bezel with a ceramic insert. The ceramic insert was highly scratch-resistant and fade-resistant, ensuring that the 24-hour markings remained clear and legible for years to come. The bezel also featured a more secure locking mechanism, preventing accidental adjustments.

Other Notable Features

The GMT-Master 16700 also incorporated several other notable features, including:

  • A sapphire crystal glass, which was more scratch-resistant than the acrylic glass used in previous models.
  • A cyclops lens over the date window, which magnified the date display for easier readability.
  • A Triplock winding crown, which provided superior water resistance.
  • A highly polished and robust Oyster bracelet, which was comfortable to wear and durable.

The GMT-Master 16700 was a significant improvement over its predecessors, offering enhanced durability, accuracy, and functionality. Its innovative features and elegant design made it a popular choice for pilots, travelers, and watch enthusiasts alike.

Design and Features of the Rolex GMT-Master 16700

The Rolex GMT-Master 16700 is a classic and highly sought-after timepiece renowned for its functionality and timeless design. It boasts a range of features that have made it a favorite among pilots, travelers, and watch enthusiasts alike.

Case and Bezel

The 16700 features a 40mm stainless steel case, which is known for its durability and robustness. The case is water-resistant to 100 meters (330 feet), making it suitable for everyday wear and even some water activities. The iconic rotating bezel of the GMT-Master 16700 is made of aluminum and is graduated in 24 hours, with alternating black and red markings to distinguish between day and night. This bezel allows the wearer to track a second time zone with ease. The bezel is unidirectional, meaning it can only be rotated clockwise, preventing accidental changes to the time zone setting.

Dial and Hands

The dial of the 16700 is available in various colors, including black, blue, and white. The dial features luminous hour markers and hands, making it easy to read in low-light conditions. The 16700 has three hands: an hour hand, a minute hand, and a 24-hour hand. The 24-hour hand is typically red and is used to track a second time zone. This hand makes a full rotation every 24 hours, allowing the wearer to easily determine the time in a different time zone.

Materials

The Rolex GMT-Master 16700 is crafted from high-quality materials, ensuring its longevity and durability. The case is made of 904L stainless steel, a highly corrosion-resistant alloy that is also used in the aerospace industry. The bezel is made of aluminum, which is lightweight and durable. The crystal is made of sapphire, a scratch-resistant material that is also known for its clarity.

Functionality of the 24-Hour Hand

The 24-hour hand is the defining feature of the GMT-Master. It is a crucial component for tracking multiple time zones. The 24-hour hand can be set independently of the hour hand, allowing the wearer to track a second time zone simultaneously. The 24-hour hand completes one full rotation in 24 hours, with the red markings indicating the night hours and the black markings indicating the day hours. To set the 24-hour hand, simply rotate the bezel until the red marker aligns with the desired time zone. The 24-hour hand will then track the time in that specific time zone.

Movements and Accuracy of the Rolex GMT-Master 16700

The Rolex GMT-Master 16700 is powered by a robust and reliable automatic movement, known for its accuracy and precision. This movement is the heart of the watch, responsible for its functionality and timekeeping abilities.

The Caliber 3185 Movement

The Rolex GMT-Master 16700 is equipped with the Caliber 3185 movement, a self-winding mechanical movement that is a testament to Rolex’s commitment to horological excellence. The Caliber 3185 is a highly sophisticated movement, featuring a number of innovative features that contribute to its accuracy and reliability.

  • The movement consists of 31 jewels and beats at a frequency of 28,800 vibrations per hour (4 Hz). This high frequency contributes to the watch’s accuracy and smooth operation.
  • The Caliber 3185 is equipped with a Parachrom hairspring, a Rolex-patented innovation made from a paramagnetic alloy. This hairspring is resistant to magnetic fields, ensuring that the watch’s accuracy is not affected by external magnetic forces.
  • The movement also features a date display, which is displayed through a window at the 3 o’clock position on the dial. The date mechanism is designed to be reliable and easy to adjust.
  • The Caliber 3185 movement is known for its excellent power reserve, which is approximately 48 hours. This means that the watch can continue to run for two full days even if it is not worn.

Accuracy and Reliability

The Caliber 3185 movement is known for its exceptional accuracy and reliability. Rolex movements are rigorously tested and certified by the COSC (Contrôle Officiel Suisse des Chronomètres), an independent Swiss organization that sets the standards for chronometer certification. This certification ensures that the watch meets stringent accuracy requirements. The Caliber 3185 movement is designed to maintain a high level of accuracy over time, even under demanding conditions.

Rolex movements are known for their robustness and durability, making them suitable for everyday wear.
