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).
Submariner 116613LN has longer lugs and bigger crown bridge, so this feels it has a bigger case. The bracelet is also made of solid 316L stainless steel and gold-cladding, matching the case perfectly. It’s front cover is made of sapphire crystal and there is water-drop enlarged at 3:00 position for the date indicator. The waterproof is 100 meter that allow for swimming.Replica Rolex Submariner 116613LN Black Dial Replica Rolex Submariner 116613LN Caseback.This replica Rolex Submariner has two edition, a normal edition and a latest V6S edition. Here is the difference between these two: there is a laser Anti-counterfeiting Rolex logo on the front case at 6:00 position, this is exactly as original edition. This logo has to use magnifier or put it at a 45 degree under the light to see it. But, the ordinary edition has the painted crown logo that can be seem directly. There comes very the original Rolex package, very fancy and high-class.Many of Rolex watch models are inspired a lot from sports, Rolex Yacht-Master is one of them. Rolex released the first Yacht-Master watch in 2007, and then released Yacht-Master II on the Basel in 2013 which became one of the most classic sporty watch in the market. Of course, then there came out many replica versions, I have seen many editions of replica Rolex Yatch-Master II, but today I would like to introduce a good edition to you, comparing to other editions on the look and function, this is the best.Rolex Yacht-Master Watch design comes from yacht racing, which we can tell from its name. This replica has a 1:1 proportion case, 44mm*14mm is a perfect size for its design. As it is designed for the professional sailing players and the yacht fans, the watch stands for Rolex’s best level on accuracy, function and technology. The case material is top-grade solid 316L stainless steel. On the white dial, we can see functions are including hour, minute, second and chronograph. These functions can be adjusted by the crown and buttons on the side, very easy to operate. There is a small red triangle hand on the dial, this is just for decoration, not moving at all. The blue bezel inspiration comes from the ocean where the yacht should be, and it can rotate both ways. Bezel is made of ceramic, new and top material in watch.
If you have a vintage Rolex Datejust manufactured prior to the introduction of Caliber 3035, then your particular model is a non-quickset Datejust. To set the date and time on a Non-Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case.Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic movement).Pull the crown out to the last notch.Rotate the crown to advance the timekeeping hands. Keep turning until the correct date appears in the date window. When the correct date appears, you are now in AM hours; now set the time accordingly taking into consideration if it is currently AM or PM.Push the crown all the way back in and screw it down to the case.To set the date and time on a Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic)Pull the crown out one notch to set the date (the timekeeping hands will continue to run in this position).Rotate the crown to adjust the date.
