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).
There is one thing I must explain, that is, many people are obsessed with those replicas manufactured by big factories like Noob, BP, J12 and others, but this does not mean that they are the best. Sometimes a cheap quartz watch will run longer than a Noob Submariner at several hundreds of dollars, every one is looking to get the best one, but you just need to find the one that perfectly fits your style.Rolex Crown Buckle Rolex Clasp Here comes the two tone GMT Master 2 replica.
