The ref. 16710 is available on either a three-piece link Oyster bracelet or a five-piece link Jubilee bracelet with hollow center links and a folded metal clasp. Older references have hollow end-links and a standard clasp, while newer references have solid end-links and a clasp with an additional safety latch. The Jubilee bracelet is the exception and is only available on reference 16710 watches with hollow end-links and a standard fold-over clasp.The ref. 116710 is only produced on a three-link Oyster bracelet. As a newer variation of the GMT-Master II, the bracelet is equipped with solid end-links, solid center links, and a newer Oysterlock clasp with a 5mm Easylink comfort extension system. Many collectors prefer this example of the Oyster bracelet as the redesigned clasp allows the wearer to adjust the length without the use of tools as their wrist fluctuates in humid or hot weather.The GMT-Master II is an absolute legend, there’s no argument about it. What it comes down to when comparing the 16710 and the 116710 is personal taste. Do you prefer the classic styling of an older sports watch? Or do you prefer a contemporary timepiece that has all the latest and greatest technologies? Either way, the Rolex GMT-Master II is a must-have for any serious watch collection.
As previously mentioned, the case also received a ceramic “Cerachrom” insert, which is virtually scratch-proof and will not fade and lose its vibrant color like aluminum. The ref. 116613 is also available with Rolex’s patented “Chromalight” lume on the dial, which offers a bright, blue glow for up to 8 continuous hours (as well as larger plots). Similar to the ref. 16613, the newer model Submariner Rolex 116613 is also available with either a blue or black dial and bezel combination. However, the Serti dials on the 116613 only come in blue or black (rather than champagne or silver), and do not feature sapphires set into the markers on the 6, 9, and 12 o’clock locations. Instead, ref. 116613 Serti dials only have 8 diamonds set in them, and feature lume-filled indexes for the 6, 9, and 12 o’clock hour markers.Both the Submariner 16613 and 116613 run on the Rolex Caliber 3135 perpetual movement with a 48-hour power reserve. However, the version of the Cal. 3135 inside the newer ref. 116613 is fitted with an upgraded paramagnetic blue Parachrom hairspring for better resistance to shocks and temperature variations.
