One of the hottest and most sought-after releases in recent years was the reference 116500 Daytona in stainless steel with black Cerachrom bezel. With the exception of its bezel, the new Daytona 116500 was virtually identical to almost any other modern, stainless steel Daytona. However, the aesthetic impact of the black Cerachrom bezel is significant, and the presence of a solid black ring around the face of the watch completely changes the overall appearance of the new ref. 116500 Daytona.Additionally, the new black Cerachrom bezel is more than a little reminiscent of the black acrylic bezels that were fitted to several vintage Daytona chronograph references manufactured during the 1960s and 1970s, such as the reference 6241 and the reference 6263. Although the two materials are significantly different in a multitude of different ways, the black Cerachrom bezel on the new 116500 Daytona is very much the contemporary equivalent of the black acrylic bezel that can be found on a number of highly-desirable, vintage Rolex Daytona references.For the most part, Rolex only moves forward with their designs as they continuously work to refine and improve their watches. However, they have been known to occasionally borrow small design elements from some of their early watches, and implement them into the latest incarnations of their ever-evolving timepieces. Sometimes these design elements get re-imagined or modernized to reflect advancements and improvements in available materials and technologies (like the Cerachrom bezel on the Daytona). Other times, like in the instance of the 24-hour hand on the new Explorer II, these vintage-inspired, design traits get pulled right off a page from a 1970s Rolex catalog and get placed on a watch currently in production.
At the heart of the Deepsea’s case is Rolex’s patented Ringlock system, which uses a super hard, nitrogen-alloyed steel central ring to internally support both the extra-thick sapphire crystal and the Grade 5 titanium caseback. While the Ringlock system is largely responsible for the overall increase in the case size of the Deepsea, it actually enables the watch to be smaller than it otherwise would be, had it were to follow a more traditional case design while still retaining its same colossal depth rating.The primary purpose of the Ringlock system is to reduce the amount of stress placed on the case of the watch. As pressure on the watch increases at greater depths, the majority of it gets exerted on the front and back surfaces of the watch. Since the nitrogen-alloyed stainless steel compression ring internally supports both the crystal and the caseback of the Deepsea, the amount of force exerted on the actual case itself remains relatively minimal. Additionally, as the crystal and caseback get squeezed together, with the majority of the force being supported by the internal compression ring, the front and back gaskets of the watch get pressed together, ensuring an extra tight seal.The caseback on the Rolex Deepsea consists of two components: an inner caseback made from Grade 5 titanium, and an outer, screw-down caseback ring that is constructed from Oystersteel (904L stainless steel). With a traditional, single-piece, caseback design, the entirety of the pressure placed on caseback gets exerted on the case of the watch itself, particularly near the threads. By separating the caseback into two components, Rolex is able to redistribute much of the force being exerted on the rear surface of the watch. The outer, screw-down ring performs the sole duty of keeping the inner, titanium caseback tight on the watch, while the nitrogen-alloyed steel compression ring ultimately supports all the pressure being exerted on the titanium case-back itself.
Omega Planet Ocean series was so popular in the world, it even has good performance in the movie 007, which has left deep impression to us accompanying with this exciting action movie. Today I am going to recommend a perfect replica of this series. Since it with advanced technology, cool matching color, dynamic appearance as the genuine. So I believe that you may fall in love with such perfect chronograph definitely.This replica Omega contains with key factors in its whole structure. Of cause, ceramic plays an important role in this replica. Its diameter was 45mm, and it case was made of solid 316 stainless steel, matched with a black ceramic bezel, Arabic numerals and scales in front of us clearly . Bezel can be hit easily when diving, but the hard ceramic can protect it from damage effectively. It was really an ideal material of bezel. In its black dial, we can see that six, nine,twelve this three Arabic numeral markers with orange coating, which can catch our eye at the first time with such bright color. Besides,the markers and scales has coated with super luminous so that can help diver read their diving time easily. The minute hand and bezel with green luminous, markers and hour hand will appear anther color, blue. With different color in luminous so as to distinguish easily. Diver can distinguish diving time and normal time quickly. That design was so considerate because this function was so important to diver. I think it was rather necessary to concern about their safety. The date display window was set in the palace of three o’clock, it was so clear since it with white big number and black background to create striking contrast in visual effect.
However, the dials of the gold Sub were not the standard black dials of their stainless steel counterparts.A few years later, around 1971, Rolex offered another colorway of the yellow gold Submariner featuring a bright blue bezel and dial. The yellow gold Submariners in blue also has the same “nipple dial” design. Particularly intriguing with the blue gold Submariner 1680/8 models is how the dials have transformed into different colors over time including lighter blues, vibrant purples, and rich reddish brown (also known as “tropical dials” in vintage Rolex terminology). Comparing the Rolex Submariner to the GMT-Master II.Two watches, perhaps the two most well-known in Rolex’s sports watch lineup, have amazing similarities, and one can be forgiven for confusing them at a distance. These two watches are, of course, the Submariner dive watch (ref. 116610) and the GMT-Master II (we’ll call it the GMT for short, but we’re talking about the current ref. 116710).The Submariner GMT Master Comparison .The individual histories of the Submariner and the GMT are well documented elsewhere, so let’s compare and contrast the two current models.First, the similarities. The Submariner and the GMT-Master II are luxury watches. Both watches are currently housed in the 40mm diameter so-called “super case” with a ceramic or Cerachrom bezel insert. This case, done in 904L stainless steel, debuted in 2007 with the GMT (the Submariner received the new case a year later). There are minute differences in the two cases, but you need to set them side by side and look very closely to see them.Both watches buckle to your wrist with the current Oyster bracelet.
