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).
On brown dial, each detail is very close to genuine, cream yellow Arabic hour markers are three-dimensional and plump. Blue steel hour and minute hands are wide, they are applied with luminous material, so are hour markers. The dial has a perfect lume effect at night. The Lume light is green and lasts for a long time. At 3 o’clock, date is displayed through a small square window, date font is white and has the correct thickness. More important, the date font is centered in the window, not too right or too left.Genuine IW327006 titanium watch is equipped with IW35111 in-house movement, which is actually developed from Swiss ETA 2892. The replica uses a Sea-Gull 2892, which has the same construction as ETA 2892, maybe the decoration on rotor and movement plate is different, but the watch has a solid case back, so I do not care the decoration, as long as it is stable. Absolutely if you do care about the subtle details, you can install one genuine ETA 2892 inside the replica by yourself, it is easy. The improved Sea-Gull 2892 movement of the replica has the same winding feel, its date adjusting direction is also correct.
Two replica IWC watches are from Z factory, we call it ZF. Both watches have real power reserve and equipped with a clone IWC 52110 movement. The Titanium Big Pilot has a reference number IW510301, while the Bronzo Big Pilot has a reference number IW501005.The following are specification of two watches.First, Big Pilot Titanium. Movement: Clone IWC 52110, Based on an Asia 23 Jeweled Automatic Movement Case: 46mm*15.5mm, Solid Titanium Case with Satin Finish Crystal: Sapphire with AR Coating Dial: Black with Superlumed Hour Markers and Hands, Working Power Reserve Indicator at 3 o’clock Bracelet: Brown Riveted Leather Strap with Deployant Clasp Water Resistant: 30m Second, the Big Pilot Bronzo.Movement: Clone IWC 52110, Based on an Asia 23 Jeweled Automatic Movement Case: 46mm*15.5mm, Solid Bronze Case Crystal: Sapphire with AR Coating Dial: Brown Dial with Superlumed Hour Markers and Hands, Working Power Reserve Indicator at 3 o’clock Bracelet: Brown Riveted Leather Strap with Deployant Clasp Water Resistant: 30m Both Big Pilot watches have a super quality, because they are from Z factory. Every detail is replicated so well, especially the delicated satin finish on the case, and the micro-sanded dial detail, they all represent the top-level manufacturing process in our watch market. However, although the power reserve indicator is working, it can not reach 7 days, you need to wind them every day to gain enough power.
Sticking with undersea operations, the Oris ProDiver collection is an interesting one, given that Oris is one of the few watch companies that remains actively engaged in dealings with commercial divers. More specifically, Roman Frischknecht is a commercial diver that has been an Oris ambassador for some time, and rather than simply being an ambassador in name, Roman has played a crucial role in the development of the ProDiver collection ahead of its launch in 2009.It was his insight that led to the creation of the brand’s bezel locking system, known as a Rotation Safety System. Given the level of safety and security protocols involved in his line of work, Roman knew that if he was to be using a conventional dive watch in a modern dive environment, there could be absolutely no room for error, thus a locking mechanism (as seen in other divers like the Omega Ploprof, among others) would be mandatory.Although the roots of the Yacht-Master II relate to activities on the water’s surface rather than deep below, its unique functionality is perfectly suited to this category. After all, the Rolex Yacht-Master II is what is often referred to as yachting timer – a countdown chronograph that can be used to properly measure the start time of a regatta, also known as a sailing race.Arguably the most complex watch in the present Rolex collection, the Yacht-Master II uses an interesting combination of bezel position, crown position, and pusher action in order to set its countdown duration between 1 and 10 minutes, with the chronograph capable of flyback (or fly-forward) functionality to the pre-set time with a single activation of its lower pusher. While many Yacht-Master II wearers are unlikely to ever use this highly specific function for its actual intended purpose. being able to run a countdown like this isn’t shy on practical daily-life applications… grilling timer, anyone?
Through the transparent case back ,we can see its movement clearly. It equipped with Asian Unitas 6498 Manual Hand wound Movement. It has anther small hand in case back which was used for adjustment so that it can be more accurate in travel time and without mistake. This powerful movement can be precise and shock resistant.Anyway, this replica IWC was general as a whole, it with low-key temperament but was luxurious as well. It was so cool when owning such wrist watch with retro and simple style due to it was hand wound watch. So how about you? It was worth of your affection.
Then there’s the much more subdued fixed stainless bezel of the Explorer II which matches the case and features a 24-hour marked scale. This feature was specifically built for explorers who need to distinguish day from night – think cave explorers or polar explorers in the height of summer when the sun never sets.For decades, the durable and waterproof Oyster case on the Explorer II measured 40mm, but upon its redesign for the 40th anniversary of the collection in 2011, it was enlarged to 42mm. However, while Rolex produces a precious metal version of the Submariner, the Explorer II is exclusively offered in 904L stainless steel, and there have never been any solid gold or two-tone models ever produced. The current Explorer II is only offered on a steel Oyster bracelet with a Oysterlock clasp, but to be honest, when it comes to the Explorer II, collectors are much more concerned with what really makes this watch: the face.The dial of the Explorer II is iconic for a few reasons. The most notable being the colored 24-hour hand which circles the face. First there’s the iconic orange 24-hour hand, originally designed to help polar and cave explorers distinguish night from day, that gained its cult-status from the original “Steve McQueen” reference. Rolex eventually brought back the bright orange hand with much fanfare. Then there’s the red 24-hour hand which graced the dial for decades – it’s distinctly different than the orange hand with a skinnier body and smaller luminous triangle at the tip. The dials with a red 24-hour hand are far less punchy than their orange counterparts, but still make the Explorer II standout from the rest of the Rolex lineup.Then there are the dial colors – available in effortlessly-cool black and the coveted ‘polar’ white. The polar dial is totally cool and clean, the white face outfitted with white lume plots and Mercedes hands outlined in black. The black face on the other hand has a totally different appeal. While it boasts the same features, the darker face really highlights the stainless steel bezel, lume hour plots and lume-filled Mercedes hands (this time in white gold rather than finished black). It’s a punchier look, and the colored 24-hour hand – especially the orange one – shines against the black a little brighter.
