Bakelite was the world&#8217;s first entirely synthetic plastic that was lightweight, relatively durable, and easy to mold into different shapes.<\/p>\n\n\n\n<p>Given those characteristics, Bakelite was initially considered a good material choice for the bezel insert of the GMT-Master watch. However, it was soon apparent that Bakelite was too brittle and had a tendency to crack &#8211; plus the radioactive glowing numerals embedded into it also posed a potential health hazard.<\/p>\n\n\n\n<p>Therefore, Rolex switched over to non-luminous aluminum bezel inserts for later GMT-Master 6542 models in the late 1950s. Furthermore, Rolex service centers also typically replaced any damaged Bakelite bezels with aluminum ones. As a result, it is incredibly difficult to find a vintage Rolex GMT-Master 6542 with its original Bakelite bezel today, and many of the surviving original Bakelite inserts show significant signs of wear or damage.<\/p>\n\n\n\n<p>Rolex made two different Bakelite bezels for the GMT-Master ref. 6542. There was the bi-color blue and red version for the stainless steel models, later nicknamed the &#8220;Pepsi&#8221; bezel. The other Bakelite bezel was a single-color burgundy one that was fitted to the solid 18k yellow gold GMT-Master 6542 watches.<\/p>\n\n\n\n<p>Legend has it that Rolex opted for the split-color design to make it easier for pilots to differentiate between night and day hours &#8211; the red portion contained the daylight hours while the blue section had the nighttime ones. However, others maintain that its bi-color appearance was intended to mirror the design of the attitude indicators that were fitted to various aircraft at the time. Either way, a split-color bezel is now considered to be one of the hallmark traits of the Rolex GMT-Master collection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Aluminum Rolex GMT-Master Bezels (1959 \u2013 2007)<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"889\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup.jpg\" alt=\"Rolex GMT-Master Bezel Reference Guide aluminum\" class=\"wp-image-42659\" title=\"Rolex GMT-Master Aluminum Bezels\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup.jpg 1200w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup-300x222.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup-768x569.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup-1024x759.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/biggroup-513x380.jpg 513w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure><\/div>\n\n\n<p>Although the ref. 6542 was eventually fitted with an aluminum bezel insert, the GMT-Master ref. 1675 was the first one designed specially to sport an aluminum bezel. The Rolex GMT-Master 1675 was introduced in 1959 and it continued to be a part of Rolex&#8217;s catalog until 1980. The stainless steel versions were first only offered with the signature blue and red bezels but these were later followed by the option of an all-black bezel in the 1960s.<\/p>\n\n\n\n<p>It&#8217;s also important to mention the controversial all-blue &#8220;Blueberry&#8221; bezel from the steel GMT-Master ref. 1675 from the seventies. These are considered to be somewhat controversial since they were never something that Rolex formerly offered the public. Some claim that these blue GMT-Master bezels were special order ones for the United Arab Emirates government, while others assert that they\u2019re not genuine Rolex bezels at all.<\/p>\n\n\n\n<p>The yellow gold GMT-Master 1675\/8 models first came equipped with brown aluminum bezels but these were later joined by the choice of a black bezel insert. In the 1970s, Rolex released a two-tone steel and gold model, the GMT-Master ref. 1675\/3, which came with three bezel options: bi-colored brown and gold bezel (aka \u201cRoot Beer\u201d), all-brown bezel, or all-black bezel.<\/p>\n\n\n\n<p>These aluminum color-schemes continued to the following references that were produced from 1980 until 1988: the stainless steel GMT-Master 16750, the yellow gold GMT-Master 16758, and the two-tone GMT-Master 16753. Furthermore, the GMT-Master 16700 (only available in stainless steel) was made from 1988 to 1999 and continued the choice between a red\/blue Pepsi bezel and an all-black bezel.<\/p>\n\n\n\n<p>However, stepping back a little to 1982, Rolex launched the first GMT-Master II model. Along with introducing a new type of GMT movement where the 12-hour and 24-hour hands are independently adjustable, the <a title=\"Rolex GMT-Master II\" href=\"https:\/\/www.bobswatches.com\/rolex-gmt-master-ii-1.html\">Rolex GMT-Master II<\/a> ref. 16760 also debuted a new bezel color scheme &#8211; red and black, also known as the &#8220;Coke&#8221; bezel. In fact, the GMT-Master II ref. 16760 only came in stainless steel and was only offered with the red\/black Coke bezel.<\/p>\n\n\n\n<p>With that in mind, the second generation of the Rolex GMT-Master II, the ref. 16710 presented in 1989, was the most varied in terms of bezel colors with Pepsi, Coke, and all-black bezels available. Plus, the yellow gold GMT-Master II ref. 16718 was available with either a black or brown bezel, while the GMT-Master II ref. 16713 came with either a black bezel, brown bezel or brown\/gold &#8220;Root Beer&#8221; bezel. Offering the widest variety of bezel colors thus far, this generation was the last GMT-Master II to feature aluminum bezel inserts.<\/p>\n\n\n\n<p>Lastly, it is also worth mentioning that among the various aluminum bezel inserts, each generation for each reference can have multiple sub-variations and this is particularly true of the older vintage references. Details such as the thickness of the font or slight variations in the style of the numerals themselves can allude to the year of production, and you often hear terms such as \u201cfat font\u201d or \u201coval 8\u201d being used to further describe the bezel inserts on vintage Rolex GMT-Master watches.<\/p>\n\n\n\n<figure class=\"wp-block-table table-responsive\"><table><tbody><tr><td><b>Bezel Color<\/b><\/td><td><b>GMT-Master I\/II Material&nbsp;<\/b><\/td><td><b>GMT-Master I\/II References<\/b><\/td><\/tr><tr><td>Blue &amp; red aluminum bezel &#8220;Pepsi&#8221;<\/td><td>Stainless steel<\/td><td>1675, 16700, 16710<\/td><\/tr><tr><td>Black aluminum bezel<\/td><td>Stainless steel Yellow Gold<br>Two-Tone Steel\/Gold (Rolesor)<\/td><td>1675, 1675\/8, 1675\/3, 16700, 16710, 16718, 16713<\/td><\/tr><tr><td>Brown aluminum bezel<\/td><td>Yellow Gold Two-Tone Steel\/Gold (Rolesor)<\/td><td>1675\/8, 1675\/3, 16713<\/td><\/tr><tr><td>Brown &amp; yellow aluminum bezel \u201cRoot Beer\u201d<\/td><td>Two-Tone Steel\/Gold (Rolesor)<\/td><td>1675\/3, 16713<\/td><\/tr><tr><td>Black &amp; red aluminum bezel &#8220;Coke&#8221;<\/td><td>Stainless steel<\/td><td>16760, 16710<\/td><\/tr><tr><td>Blue aluminum bezel &#8220;Blueberry&#8221;<\/td><td>Stainless steel<\/td><td>1675<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>It&#8217;s important to mention that aluminum bezels have a tendency to fade over time, especially with prolonged exposure to the sunlight. However, aluminum bezels do not all fade in the same manner. This explains why you\u2019ll often see a wide range of colors present among vintage GMT-Master watches with faded bezels.<\/p>\n\n\n\n<p>For instance, some Pepsi aluminum bezels have faded in such a way that the once-red portion is now light pink, light orange, or even bright fuchsia &#8211; it really just comes down to the age of the insert and the specific conditions that it was exposed to during its lifetime.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ceramic Rolex GMT-Master II Bezels (2005 \u2013 Present)<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"306\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic.jpg\" alt=\"Rolex GMT-Master Bezel Reference Guide Cerachrom ceramic \" class=\"wp-image-42660\" title=\"Rolex GMT-Master Cerachrom Bezels\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic.jpg 1200w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic-300x77.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic-768x196.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic-1024x261.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/ceramic-585x149.jpg 585w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure><\/div>\n\n\n<p>2005 marked the 50th anniversary of the GMT-Master watch. To celebrate, Rolex released an entirely revamped GMT-Master II model complete with a redesigned case, a new movement, and most importantly, a brand new material for the bezel.<\/p>\n\n\n\n<p>The 18k yellow gold Anniversary GMT-Master II ref. 116718 featured a black bezel made from Cerachrom, which is Rolex&#8217;s proprietary ceramic material that is both scratch-resistant and fade-proof. Rolex later followed up the solid gold model with the two-tone GMT-Master II ref. 116713 in 2006, and the stainless steel ref. GMT-Master II ref. 116710 in 2007.<\/p>\n\n\n\n<p>Rather than printed markings like on aluminum bezel inserts, the 24-hour scales on Rolex\u2019s new Cerachrom bezels require a much more complex manufacturing process. The numerals and markings are first molded into the material and then the whole insert is subjected to Physical Vapour Deposition (PVD) where the surface is coated entirely in a layer of yellow gold, pink gold, or platinum. The metal is then polished away from the ceramic surface leaving behind metal-filled graduations. Initially, Rolex only offered the Cerachrom bezels across all three metal cases in monochromatic black, claiming that it would be impossible to produce a two-tone version from a single piece of ceramic.<\/p>\n\n\n\n<p>However, in 2013, Rolex seemingly did the impossible by introducing the stainless steel GMT-Master II ref. 116710BLNR with a bi-color, black and blue Cerachrom ceramic bezel insert. Like all split-color GMT bezels before it, this one quickly picked up a nickname and it\u2019s now known as the Rolex &#8220;Batman&#8221; among collectors and enthusiasts.<\/p>\n\n\n\n<p>This was the world&#8217;s first single ceramic component featuring a two-color combination and made major headlines when it first made an appearance. To achieve this two-tone ceramic insert, Rolex adds a special solution to one half of the bezel, then during the sintering process, that treated area transforms into another color.<\/p>\n\n\n\n<p>Other two-tone Cerachrom ceramic bezels soon followed including the blue and red Pepsi bezel, first only available on the 18k white gold GMT-Master II ref. 116719BLRO in 2014, and then on the stainless steel GMT-Master II 126710BLRO in 2018. There&#8217;s also the new Root Beer style bezel in the form of the brown and black Cerachrom bezels that are found on the Everose gold GMT-Master II 126715CHNR and two-tone Everose Rolesor 126711CHNR models.<\/p>\n\n\n\n<figure class=\"wp-block-table table-responsive\"><table><tbody><tr><td><b>Bezel Color<\/b><\/td><td><b>GMT-Master II Material&nbsp;<\/b><\/td><td><b>GMT-Master II References<\/b><\/td><\/tr><tr><td>Black Cerachrom bezel<\/td><td>Stainless steel Yellow Gold Two-Tone Steel\/Gold (Rolesor)<\/td><td>116710LN, 116718, 116713<\/td><\/tr><tr><td>Blue &amp; red Cerachrom bezel &#8220;Pepsi&#8221;<\/td><td>White Gold Stainless Steel<\/td><td>116719, 126719, 126710BLRO<\/td><\/tr><tr><td>Blue &amp; black Cerachrom bezel &#8220;Batman&#8221;<\/td><td>Stainless Steel<\/td><td>116710BLNR, 126710BLNR<\/td><\/tr><tr><td>Brown &amp; black Cerachrom bezel &#8220;Root Beer&#8221;<\/td><td>Everose Gold Two-Tone Steel\/Everose Gold (Rolesor)<\/td><td>126715CHNR, 126711CHNR<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Today, all of the current-production Rolex GMT-Master II models come equipped with two-tone Cerachrom bezels, regardless of their metal type (except for the gem-set versions).

These models feature precious gems such as diamonds, sapphires, and rubies set into the bezel rather than the standard 24-hour scale layout. However, Rolex sets the gems into the bezel in such a way where the scale is still somewhat decipherable, complete with an upside-down triangular-cut gem at the 12 o\u2019clock location. There are even some gem-set Rolex GMT-Master II bezels with diamonds, rubies, and sapphires that mimic the iconic red and blue \u2018Pepsi\u2019 colorway.<\/p>\n\n\n\n<p>Rolex released the yellow gold GMT-Master II ref. 116758SANR, 116758SA, and 116758SARU models in 2006. The following year, the white gold GMT-Master II ref. 116759SANR, 116759SA, and 116759SARU joined the collection, and all of these models feature ultra-luxurious bezels set with breathtaking gemstones.<\/p>\n\n\n\n<p>Additionally, Rolex also unveiled the GMT-Master II ref. 116769TBR in 2007. Blanketed with over 30 carats of diamonds set into its case, dial, bezel, and bracelet, the Rolex GMT-Master II \u201cIce\u201d retailed for a whopping $485,350. Unlike the other gem-set GMT-Master II bezels, the Rolex \u201cIce\u201d bezel is only rendered in one color, consisting almost entirely of baguette-cut diamonds and one triangular-cut diamond at 12 o\u2019clock.<\/p>\n\n\n\n<p>In early 2020, Rolex quietly released the ultra-lavish Everose gold GMT-Master II 126755SARU, which features a solid 18k Everose gold case with a \u2018Pepsi\u2019 gem-set bezel that features diamonds, blue sapphires, and red rubies.<\/p>\n\n\n\n<figure class=\"wp-block-table table-responsive\"><table><tbody><tr><td><b>Bezel Gems<\/b><\/td><td><b>GMT-Master II Material&nbsp;<\/b><\/td><td><b>GMT-Master II References<\/b><\/td><\/tr><tr><td><span style=\"font-weight: 400;\">Black sapphires &amp; diamonds<\/span><\/td><td><span style=\"font-weight: 400;\">Yellow Gold<\/span>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">White gold<\/span><\/p>\n<\/td><td><span style=\"font-weight: 400;\">116758SANR, 116759SANR<\/span><\/td><\/tr><tr><td><span style=\"font-weight: 400;\">Blue sapphires &amp; diamonds<\/span><\/td><td><span style=\"font-weight: 400;\">Yellow Gold<\/span>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">White Gold<\/span><\/p>\n<\/td><td><span style=\"font-weight: 400;\">116758SA, 116759SA<\/span><\/td><\/tr><tr><td><span style=\"font-weight: 400;\">Blue sapphires, red rubies, diamonds<\/span><\/td><td><span style=\"font-weight: 400;\">Yellow Gold<\/span>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">White Gold<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Everose Gold<\/span><\/p>\n<\/td><td><span style=\"font-weight: 400;\">116758SARU, 116759SARU, 126755SARU<\/span><\/td><\/tr><tr><td><span style=\"font-weight: 400;\">Baguette-cut diamonds<\/span><\/td><td><span style=\"font-weight: 400;\">White Gold<\/span><\/td><td><span style=\"font-weight: 400;\">116769TBR<\/span><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit.jpg\" alt=\"Rolex GMT-Master Bezel Reference Guide original brown Bakelite \" class=\"wp-image-42322\" title=\"Rolex GMT-Master 6542 - Brown Bakelite Bezel\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit.jpg 1200w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit-300x200.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit-768x512.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit-1024x683.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2020\/07\/Rolex_GMT_6542_5D3_1917-Edit-570x380.jpg 570w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\">GMT-Master Bezel Nicknames and Letter Codes<\/h2>\n\n\n\n<p>Depending on whom you talk to, Rolex GMT-Master bezels are commonly referred to by their nicknames or by their letter codes.
