5 Surprising Things We Learned About The Rolex GMT


Rolex GMT is a grail watch of world travelers, who frequently set off intercontinental journeys for personal or professional reasons. A hot favorite of secondary and vintage markets, this timepiece enjoys an illustrious history that dates back to the 1950s. Since its induction in 1955, the rolex gmt family has evolved to produce a number of watchmaking icons highly sought-after by fine watch enthusiasts around the world. In this article, we will discuss about five amazing things in connection with the iconic GMT wristwatch.

(1) Difference between GMT Master and GMT Master II

When Rolex launched its GMT watch in 1955, it heralded a new era in the history of watchmaking. Specially created for aviators who operate long-haul flights, the first generation of this family is known as GMT Master. The special features include an Oyster case with external rotating bezel, and a self-winding movement with a date at 3 o’clock and an additional hour hand for displaying GMT. The rolex gmt master watches were produced from 1955 to the early 1990s.

The last model to be released from the GMT Master series was reference 16700, which was introduced in 1989. The historical references from this prestigious wristwatch family are in high-demand in the vintage watch singapore market.

The second generation of the GMT family was born in the 1980s after the company developed a new self-winding movement (caliber 3085) with an independently adjustable GMT hand. The first timepiece from the Rolex GMT Master II family (reference 16760) was launched in 1983. The most recent model in the present generation is Reference 126720 VTNR, the left hander’s version unveiled at this year’s “Watches and Wonders” event. All GMT Master II models introduced since 2015 are equipped with the Calibre 3285, which is more advanced and energy efficient.

The most fundamental difference between the above two generations is the type of GMT mechanism used with the movements. The Master II series features independently adjustable 24-H hand that allows the watch to indicate three time-zones. In comparison, GMT master models feature a non-independent 24-H hand (which moves when you adjust the hour hand) thus display only two time-zones.

(2) GMT Bezel

The graduated 24-hour bezel is a signature feature of Rolex GMT watches. Majority of the models from this distinguished watch family feature dual-tone bezel for differentiating between the day (0600 to 1800) and night (1800 to 0600) on the 24-H scale of the bi-directional rotating bezel. The popular two-color themes include Blue & Red, Black & Red, Black & Blue and Black & Green.

Initially, the company used Bakelite for manufacturing two-tone bezel-inserts. In the late 1950s, Rolex began equipping its GMT watches with aluminium bezels. The brand also offered their customers to replace Bakelite bezels of their wristwatches with more durable aluminium counterparts. Rare to find, the first generation GMT master models with the original Bakelite bezels are thus highly sought-after by rolex vintage watch collectors.

In 2005, Rolex introduced the Cerachrom bezel-insert for the GMT Master II series with the 50th-anniversary white gold edition. This specially developed ceramic material is highly corrosion-resistant, scratch-proof and UV-resistant. The early generation Cerachrom bezel-inserts were single-toned. In 2013, the first GMT watch with a bi-color Cerachrom bezel-insert was launched. As of now, all the new GMT Master II models feature dual-tone bezels made of Cerachrom ceramic material.

The brand also used monotone bezels in some models. For example, the rolex gmt master ii black in steel (116710LN) features an all black bezel and a matching color dial.

(3) Nicknames

Most Rolex GMT watches come with interesting nicknames, from the popular Pepsi to the newly launched Sprite.

The main inspiration for these names is the color theme of the particular model. For example, the rolex gmt pepsi name came from the dual tone “Blue and Red” bezel evoking the bottle cap of the famous American soft drink brand. The very first Rolex GMT watch featured the so-called Pepsi color bezel. Similarly, the GMT model with a “Black & Red” bezel is called Coke because it reminds us the signature color theme of Coca Cola.

Another interesting designation is rolex gmt root beer, which features a distinct “black and brown” bezel combination evoking the color of a traditional North American soft drink made using the root bark of the sassafras tree.

Introduced in 2019, the GMT Master II 126710 BLNR is known as Batgirl. Sprite is the nickname given to the newly released “black and green” GMT Master II watch with the crown on the left side.

(4) Weekend-proof Autonomy

It usually refers to mechanical timepieces with longer power reserve so that the wearer can unworn the wristwatch on a Friday evening and worn it back on again on Monday morning without winding the movement. All the new GMT Master II models are equipped with the Manufacture Calibre 3285. Featuring the state-of-the-art Chronergy escapement, this self-winding movement has a power reserve of 70 hours, making the timepiece a truly weekend-proof watch.
