The ref. 16710 is outfitted with a standard 40mm Oyster case with water-resistance up to 100 meters and a protective sapphire crystal over the dial. The bezel is equipped with an aluminum insert in either all-black, red and blue, or red and black. Depending on the year of production, the watch is also available on the secondary market with cases that have either lug holes or no lug holes, and the luminous material on the dial will vary, as Rolex made the switch from Tritium to LumiNova during the production of the reference 16710 GMT-Master II.With the release of the ref. 116710 came a brand new case design that includes the upgrade to a triple-sealed Triplock screw-down crown, a new bezel mounting system that operates on 24 clicks instead of 120, a tougher “Cerachrom” bezel insert crafted from a scratchproof ceramic material, and a “Maxi” dial topped with larger hour markers and wider hands. The 40mm case also received a larger crown guard and wider lugs, earning it the nickname the “Super Case” among collections due to its thicker and more aggressive overall appearance.The ref. 16710 is equipped with the self-winding Rolex Caliber 3185 perpetual movement, which includes a Quickset function for easy adjustment of the date mechanism, hacking, an independent 24-hour hand, and a 48-hour power reserve. However, near the very end of production of the ref. 16710, Rolex switched movements, and later-era examples of the reference 16710 were equipped with the Caliber 3186 movement. The Caliber 3186 has the same specifications as the Caliber 3185 but is now equipped with Rolex’s newer paramagnetic blue Parachrom hairspring and a smoother operating jump-hour hand. With that in mind, all reference 116710 GMT-Master II watches run solely on the Caliber 3186.
The first ceramic bezel Submariner appeared in 2009 with the introduction of the steel and gold Rolex reference 116613. A stunning blend of classic and modern dive watch design, the ref. 116613 has since become a highly sought-after dive watch, both at retail and on the pre-owned Rolex market. Other metal variations of the ceramic (aka “Cerachrom”) bezel Submariner would later follow. However, none is as intriguing as the Rolex Submariner two-tone example.The Rolex Submariner was introduced to the market in the early 1950s and was the first timepiece in the brand’s catalog to offer water resistance up to 100 meters. This depth rating would eventually be increased to up to 300 meters, where it remains for the modern versions of the Submariner that are sold today. Other notable upgrades made to the line over the past six decades include improved materials (904L Oystersteel), longer-lasting lume (Chromalight), higher-beat Caliebr 3135 perpetual movements, tougher scratch-resistant sapphire crystals, and unidirectional rotating timing bezels.The Submariner was first offered in stainless steel, then in yellow gold. The first two-tone Submariner wasn’t released until 1984, with the reference 16803. This take on Rolex’s famous professional diver introduced the line to a brand new level of collectors who sought a gold Rolex but didn’t have the budget for an all-gold timepiece. Fast forward to 2009 with the release of this article’s featured ref. 116613, a completely redesigned dive watch with an upgraded bracelet and case, a redesigned bezel fitted with a ceramic insert, and a larger display on the dial.The Rolex Submariner is a dive watch legend. From its many appearances in the James Bond franchise to gracing the wrists of numerous A-list celebrities, the Submariner has become one of the most recognizable and coveted luxury watches in the world. The line is varied and offers options in either an all Oystersteel (904L stainless steel), Rolesor (two-tone steel and gold), or solid 18k gold. Today, we will compare two of the most iconic two-tone Rolex Submariner references – the Rolex 16613 and Rolex 116613.
