The case is 40mm in diameter and made of 316L stainless steel, round bezel is very thin, so we can see a very big dial under the sapphire crystal. Whole case is brushed, including four lugs. The face of bezel is also brushed while polished on edge. Like genuine, you can operate the two pushers to start or stop chronograph. Case back is locked by four screws, there are vertical brushing on the center. When open the case back, the inside has beautiful geneva stripes and correct engravings like genuine watch.Dial is blue. There are two small dials at 6 and 12. The subdial at 6 o’clock is displaying small seconds, while the subdial at 12 o’clock is for 30-minute chronograph. The two small dials are sunken on the main blue dial, together with the beveled inner bezel, the whole dial shows a 3D visual effect. Besides, silver Arabic numeral hour markers are also three-dimensional.
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.
The Datejust and Date have always featured identical functions – a self-winding time and date movement with an instantaneously changing date display. Additionally, the two watches have often run on the same calibers as well (as have the smaller versions of both models) with both switching to quickset date movements in the late 1970s.However, today the current-production Datejust 36 and Datejust 41 watches are powered by the latest generation Caliber 3235 movement with a 70-hour power reserve, while the Date 34 still runs on the previous generation Caliber 3135 with a 48-hour power reserve.Overall, the Rolex Date is the smaller and simpler version of the Rolex Datejust with fewer options available from the factory but offering near-identical functionality.Holiday season is right around the corner and for many of us, that means traveling somewhere to spend some quality time with family. Whether you’re flying across the country for Thanksgiving, to another country for winter break, or voyage frequently as part of your day-to-day life, here are some of our favorite Rolex watches for women who travel.Given that the Rolex GMT-Master watch was invented for people who fly planes for a living, it comes as no surprise that this would be a top pick for a travel watch.
While bidirectional rotating bezels may be quicker for wearers to turn to the appropriate spot, as a dive bezel it’s not the best option. If the bezel gets accidentally knocked, this could cause divers to miscalculate how long they have been underwater. Therefore, a unidirectional bezel is more prudent because accidental knocks to the bezel can only result in overestimating immersion time – it’s far preferable to start ascending to the surface earlier or spend longer than necessary at a decompression stop.Rolex began equipping the Submariner with unidirectional bezels starting with the Submariner Date ref. 16800, which was introduced around 1979. The no-date Submariner model received a unidirectional bezel with the introduction of the Submariner ref. 14060 in 1990.Like the previous generation, the new unidirectional bezels included aluminum bezel inserts. In 1983, Rolex introduced the first two-tone Submariner model in the form of the Submariner Date ref. 16803, which sported a yellow gold knurled bezel with a black or blue aluminum insert. To celebrate the 40th anniversary of the Submariner in 2003, Rolex introduced the stainless steel Submariner Date ref. 16610LV with a green bezel insert.In 2008, Rolex introduced the first Submariner models equipped with unidirectional bezels featuring Cerachrom inserts. Cerachrom is Rolex’s proprietary ceramic alloy that is not only resistant to scratching but also to fading. The 60-minute graduations are cut into the bezel and then the ceramic bezel insert is fully coated with either yellow gold (for yellow gold and two-tone models) or platinum (for white gold or steel models). The gold/platinum is then polished away from the ceramic surface until only the recessed numerals and markings are left with the metal filling.By 2012, Rolex had rolled out the Cerachrom bezels across all Submariner models and color options include black, blue, and green. A quick way to know the color of the bezel is to look at the letters in the reference number: LB (blue bezel), LN (black bezel), and LV (green bezel).
Second, the shape of the hands, especially the propeller-shaped end of the central second-chronograph hand is made correct.The final thing you concern about is if the replica watch has a full chronograph function. I must say yes. The watch is equipped with the most widely used Asia Valjoux 7750 movement, you can operate the chronograph buttons like you do on a genuine. Thanks to the solid case, Z factory did not make too much modification on the movement, so it could maintain a high stability of the original movement.It is a new arrival, but Z factory did not raise its price, it is sold at much cheaper than other Spitfire watches, so I recommend it if you are a pilot watch fan of IWC.
