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).
Other Submariners do not have engravings on case back. From the case back, you can see the pins that connect the case and bracelet, they are crafted to be better so that could firmly connect case head, every piece of the bracelet link is made of solid 316L stainless steel, holding the replica is like wearing a genuine Rolex.In a word, the replica inherits all advantages of Noob 116610 LN Submariner but has its own unique features.This is another great vintage project in the replica watch market, which comes with a replica Rolex Submariner. The replica is manufactured by the same factory as Daytona 6214. I have introduced several pieces of replica watches including Panerai and Rolex in my blog, many of them attracted a lot of readers here and they asked me the price, I have to tell them these vintage watches are all sold at reasonable prices. Ref. 5510 should have be the oldest Submariner model Rolex made, it already had the features of modern Rolex Submariner like Mercedes-Benz hands and rotating bezel, however Submariner 5510 also has the iconic features of its own. Here I will introduce the replica to let you know more about those vintage Rolex watches made in old times.The most outstanding place that also makes the watch full of vintage style lies in its dial, which is black. The hour markers of 3-6-9 and bar-shaped also make it different from other Submariner watches. These hour markers are all applied with yellowish luminescence, so are the hands. The dial printings are also in yellow color except the words “200m = 660ft”. Next to the hour markers, there is a circle of minutes scales in track style, which is also different from modern Submariner watch. We actually call such dial “Explorer Style”. The bezel insert is black and features white printings, there is a pearl at 12 o’clock in red triangle background.
