Rolex GMT-Master II 16760 "Fat Lady" Overview

The Rolex GMT-Master II reference 16760, often referred to as the "Fat Lady" or "Sophia Loren" by collectors due to its thicker case profile, represents a significant evolution in the GMT-Master line. It was the first GMT-Master II model, introducing an independently adjustable 24-hour hand, which allowed for the tracking of three time zones simultaneously when used in conjunction with the rotating bezel. This reference also marked the introduction of the sapphire crystal to the GMT-Master series, enhancing its durability and water resistance compared to earlier models. It was exclusively produced with a black and red bezel insert, known as the "Coke" bezel.

This reference features a 40mm stainless steel Oyster case, housing the Caliber 3085 automatic movement. The movement provides a power reserve of approximately 42 hours and incorporates the quickset date function. The watch is fitted with a sapphire crystal, contributing to its water resistance rating of 100 meters. The robust construction of the Oyster case and bracelet ensures its suitability for daily wear.

As a transitional reference produced for a relatively short period, the 16760 holds a distinct place among Rolex collectors. Its unique case proportions and the distinction of being the inaugural GMT-Master II model contribute to its appeal. The limited bezel color option and the introduction of new technical features make it a notable piece for those interested in the development of Rolex's professional tool watches.

The GMT-Master reference 16700 was introduced as a transitional model, serving as a more traditional alternative to the then-new GMT-Master II reference 16710. It maintained the original GMT-Master functionality, allowing for the tracking of two time zones simultaneously through its independent 24-hour hand linked to the main hour hand. This reference represents the final iteration of the original GMT-Master line, preceding the full transition to the GMT-Master II architecture. It was produced concurrently with the early GMT-Master II models, offering a choice for collectors who preferred the simpler GMT mechanism.

This reference features a 40mm stainless steel case, characteristic of many Rolex professional models of its era. It is powered by the automatic Caliber 3175, which provides a power reserve of approximately 48 hours. The watch is fitted with a sapphire crystal, enhancing its durability and scratch resistance, and offers a water resistance of 100 meters. The bidirectional rotating 24-hour bezel, often seen with a "Pepsi" (blue and red) or "Coke" (black and red) insert, allows for the tracking of a second time zone.

For collectors, the 16700 holds significance as the last of the true GMT-Master series, distinct from the GMT-Master II's independently adjustable 24-hour hand. Its production period, spanning from the late 1980s to the late 1990s, places it at an interesting juncture in Rolex's history. It appeals to those who appreciate the classic GMT-Master design and functionality, often sought after for its robust construction and the availability of various bezel insert options.

The GMT-Master reference 16750 represents a transitional period for the model, bridging the gap between the long-running vintage reference 1675 and the modern five-digit references. It introduced significant technical updates while retaining much of the aesthetic character of its predecessor. This reference is notable for incorporating a quickset date function, a crucial advancement for user convenience that was absent in earlier GMT-Master models. It maintained the classic GMT-Master design language, making it appealing to collectors who appreciate both vintage aesthetics and improved functionality.

This reference features a 40 mm stainless steel case, housing the automatic caliber 3075. This movement provides a power reserve of approximately 42 hours and includes the aforementioned quickset date complication. The watch is fitted with an acrylic crystal, consistent with its transitional vintage status, and offers water resistance up to 100 meters. The bidirectional rotating aluminum bezel with a 24-hour graduated insert allows for the tracking of a third time zone.

For collectors, the 16750 is particularly interesting due to its relatively short production run and the combination of vintage and modern features. Early examples often feature matte dials, while later versions transitioned to gloss dials with white gold surrounds for the hour markers, offering distinct variations for enthusiasts. Its position as a transitional reference makes it a key piece in understanding the evolution of the GMT-Master line, appealing to those seeking a watch with both historical significance and enhanced practicality.
