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.
Part of the brand’s collection since 1945, the Rolex Datejust is the ultimate everyday luxury watch. While the model comes in a vast assortment of styles including different sizes, metals, bracelets, bezels, and dial designs, what remains constant across all Datejust watches is its time and date functionality. The hour, minute, and seconds hands are always placed at the center while the date window is always found at the 3 o’clock position. In true Rolex fashion, the Datejust watch is easy to use and operate but there are a few things to keep in mind when setting the time and date. Read on for our quick guide on how to set the date and time on a Rolex Datejust.Earlier models of the Rolex Datejust did not yet have the quickset date feature. A quickset date feature means that the date can be set independently from the timekeeping hands. Conversely, on a non-quickset Datejust, the minute and hour hands have to be advanced past midnight to change the numeral in the date window.Rolex introduced the quickset date function to the Datejust lineup in 1977 with the introduction of Caliber 3035 movement. So if your Datejust was made in 1977 or later and is powered by Caliber 3035 or subsequent movements (Cal. 3135, 3136, or 3235) then it has the quickset feature.Regardless of when a Datejust was produced, they all come equipped with a screw-down winding crown to ensure the watch’s water resistance. Therefore, a Rolex winding crown must be unscrewed first before any adjustments can be made.
Rolex has been manufacturing watches with 34mm case diameters for the majority of their long and distinguished history; however, these “mid-size” models such as the Date and Air-King often get overlooked due to the multitude of options that exist in the more standard, 36mm Rolex Oyster Perpetual case size. However, Rolex has manufactured a number of excellent watches – both vintage and contemporary – that have 34mm case diameters, and their highly versatile size allows them to look at-home on wrists of virtually any gender or measurement.Although the Datejust collection has historically had a case diameter of 36mm for the standard full-size model, Rolex also manufactures a line of watches called the Date that offers many of the same design traits and features of the Datejust – even the same movement too – only in a slightly smaller overall package.One of the most “quintessentially Rolex” watches currently in production with a 34mm case diameter is the reference 115234 Date. With a Cyclops magnification lens, stainless steel Oyster bracelet, and 18k white gold fluted bezel, the reference 115234 Date checks all the same design boxes as the Datejust, just with a slightly reduced size. Additionally, since the 34mm Date and the 36mm Datejust share the same movement, the reference 115234 is in no way a “lesser” watch compared to the Datejust, just one that is 2mm smaller.Since consumer trends favored smaller wristwatches in past decades, a number of great vintage Rolex references exist with 34mm case diameters. One of the longest-running Rolex models of all time is the reference 5500 Air-King, which boasts a super clean and minimal dial design that perfectly complements its slightly reduced case size.The reference 5500 remained in production for thirty-seven years, during which time it was fitted with both Rolex’s Caliber 1520 and Caliber 1530 movements – neither of which were chronometer-certified. Due to their long production run, reference 5500 Air-King watches were manufactured in relatively large numbers and can still be purchased for very reasonable prices. Fitted with one of the cleanest and least text-heavy dials found inside any Rolex watch, the Air-King 5500 pre-dates the widespread implementation of chronometer-certified movements and represents one of the best entry points into vintage Rolex collecting.Although the Day-Date President is the classic all-gold Rolex watch, it has never been manufactured in a size smaller than 36mm. However, throughout its history, Rolex has produced a number of all-gold watches within their Date collection that have 34mm case diameters, and lack the additional complication for displaying the day of the week that is found on the flagship Day-Date line of watches.One of the more modern incarnations of the all-gold 34mm Date is the reference 15238, which stands out due to a number of characteristics that help separate it from previous iterations of Rolex’s all-gold 34mm Date watch. While earlier examples were made from 14k gold, there reference 15238 is craft from 18k – the same as what Rolex uses to manufacture their flagship Day-Date President watch. Additionally, the Date 15238 is fitted with Rolex’s Caliber 3135 movement and a synthetic sapphire crystal, which give it all the ingredients necessary to be a fairly modern watch.
And of course, the movements of both watches are COSC certified chronometers.But the bracelets are where we begin to see differences between the Sub and the GMT. The Submariner gets Rolex’s folding Oysterlock safety clasp with their Glidelock extension system. The GMT’s Oyster bracelet, on the other hand, buckles with a simpler folding Oysterlock safety clasp with and Easylink 5 mm comfort extension link. There have been multiple cases where the Submariner and the GMT are compared.The biggest difference between the two watches is the GMT’s additional hour hand tipped with a triangular “arrowhead.” This hand indicates the hours in 24-hour format. This fourth hand can be set independently of the main hour hand, and the 24-hour time is marked on the bi-directional rotating bezel.In fact, when moving across time zones, one can move the GMT’s regular hour hand to reset to local time without affecting the 24 hour hand’s position. This makes such adjustments easy and routine for the busy traveler.With the Submariner, choices of bezel and dial colors depending on the metal chosen means you have numerous variations from which to choose. The uni-directional bezel is marked in typical dive watch fashion of five minute increments, numbers each ten minutes, and the first fifteen minutes in one-minute tick marks.Even though the GMT features Rolex’s patented Triplock screw-down crown system, the watch is only rated to 100M/330Ft (in all metals). The Submariner is rated to 300M or 1000Ft. This is interesting, given that both watches are housed in the super case.So there you have it. The Submariner and the GMT-Master II are fraternal twins, nearly identical, but each with its own capabilities.5 of the Best Looking Rolex Cerachrom Bezels Rolex isn’t known for being particularly bold with design. However, what they are known for is being innovative, whether that’s creating their own alloys like Everose or mastering the art of hard-to-achieve colored dials. Most recently, one of their biggest innovations to roll out was their new and improved Cerachrom bezels, like those that can be found on the Rolex Daytona and GMT-Master II.Because the bezel on a watch is so exposed, it is often susceptible to shocks, corrosion, fading and scratching. Therefore, Rolex wanted to upgrade specific Professional models in their Oyster collection from aluminum bezel inserts to something much more durable. In typical Rolex fashion, they’ve created their own durable ceramic called Cerachrom – which is a mix of the words “ceramic” and the Greek word for color, “chrom.”Today, we’re looking at the best of the best of these Cerachrom bezels. The most good looking, handsome, and striking examples since this new material was rolled out.I wanted to note this one first because it just looks so different than the other Cerachrom bezels that Rolex has produced. That matte, sandblasted ceramic bezel has this effortlessly modern feel, and is kind of everything that you’d want to see out of a new material. Plus, that black bezel just totally pops against the Everose case.They said it couldn’t be done. When Rolex first unveiled their Cerachrom bezel in 2005, they did so in one solid color and actually admitted that it was just too hard to do a two-colored bezel with the material. Then in 2013, they presented us with this – a blue and black bezel that became instantly iconic. It was a great addition to the GMT-Master II lineup, but it also further illustrates Rolex’s dedication to innovation. Plus it’s totally sharp, right?This is a jaw-dropping look – that Chestnut brown monobloc Cerachrom against an icy blue dial. It’s unique, it’s beautiful, and it’s all executed so well. The Daytona is already a love-it-or-hate-it watch, so it’s fitting that they’ve chosen to go with such a bold, and frankly fun choice for the bezel here.The blue Cerachrom bezel on the Yacht-Master II is just striking. The way the bold blue contrasts against the white dial and Oyster case is just so elegant.
