Lastly, both the 16613 and the 116613 are fitted with stainless steel and 18k yellow gold Oyster bracelets. Depending on the year released, the ref. 16613 has either solid or hollow end-links, either a stamped or link-style fold-out extension system, and either a gold-through or an all-steel clasp. Collectors have different preferences on 16613 bracelet styles, making it a fun watch to collect.The ref. 116613 offers a more substantial hold on the wrist than its 5-digit predecessor and features solid gold center links, solid end-links, and a machined Oysterlock clasp with an innovative Glidelock extension system. The solid construction of the bracelet balances the Super Case nicely on the wrist for a supremely comfortable hold, even over wetsuits.While the ref. 116613 is noticeably more modern in appearance, it still boasts many similarities to the ref. 16613 in the form of a versatile two-tone finish, similar dial and bezel color options, the same water-resistance of up to 1,000 feet (300 meters), and an Oyster bracelet that wears comfortably and allows for tool-free adjustment over wetsuits. When collecting, it ultimately comes down to preference; do you prefer a classic or a contemporary dive watch?The Rolex Sea-Dweller Deepsea is the most robust and over-engineered dive watch in Rolex’s current lineup. While the regular Sea-Dweller is water-resistant to an insane depth of 4,000 feet, the Deepsea has an absolutely abyssal depth rating of 12,800 feet, which is more than 100 times further below the surface of the ocean than any human could physically survive.Although the case of the standard Rolex Sea-Dweller is not all that different from that of a Submariner, the Deepsea has a re-designed case architecture that allows it to stand up to the crushing pressures found at 12,800 feet below sea-level. As a result of its more rugged and highly specialized build, the Deepsea is among the largest Rolex watches currently in production, with a case diameter of 44mm, and an overall thickness of just under 18mm.
The green-tinted sapphire crystal fitted to the reference 116400GV Milgauss has quickly become one of the defining characteristics of Rolex’s anti-magnetic line of watches. The Rolex Milgauss was first introduced in 1956; however, it was not until 2007 that it received its now-signature, green sapphire crystal – an exclusive feature that was originally introduced as a way for Rolex to celebrate the 50th anniversary of their Milgauss line.No other watch in Rolex’s current catalog is fitted with a green-tinted (or any other color) sapphire crystal. However, at the present time, all Milgauss watches that are currently in production leave the factory with green sapphire crystals. Rather than simply being a layer or coating, the light green tint is present throughout the entire material of the crystal, and will not fade or discolor after prolonged wear and use.Rolex claims that it took them many years of research and development to master and perfect the secret procedure of manufacturing their green-tinted sapphire crystals and that the actual process of producing the crystals takes multiple weeks. What is most interesting is that despite a usual eagerness to patent their various in-house technologies, Rolex claims that the green sapphire crystal in the Milgauss is “not patented, as it is so difficult to make that no one else would even venture to try.”Rolex will never reveal their exact formulas and secrets about how they manufacture the green-tinted sapphire crystals fitted to the Milgauss; however, we do know some general information about green-colored synthetic sapphire and the production of sapphire watch crystals as a whole.There are a number of different ways to produce synthetic sapphire, all of which fall into the following general methods of production: melt growth, solution growth, and high-temperature/high-pressure growth. It is hypothesized that Rolex uses a hydrothermal method of production for its synthetic sapphire crystals, which is slow, expensive, and uses heat and pressure to imitate the conditions present deep inside the earth that is responsible for the production of naturally-occurring crystalline gemstones.
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.
