The IWC Portuguese Annual Calendar replica is equipped with an Asia IWC 52850 automatic movement, ZF disassembled all 326 components of original movement, after lots of trials of data analysis, the clone movement looks 90% the same as original 52850, besides, its adjusting method and winding feel are 100% the same as original. Because this IWC Portuguese watch has a see-through case back, so on the replica movement, ZF factory needs to work hard on the movement decoration. The following are photos of four Portuguese Annual Calendar watches.
The first ceramic bezel Submariner appeared in 2009 with the introduction of the steel and gold Rolex reference 116613. A stunning blend of classic and modern dive watch design, the ref. 116613 has since become a highly sought-after dive watch, both at retail and on the pre-owned Rolex market. Other metal variations of the ceramic (aka “Cerachrom”) bezel Submariner would later follow. However, none is as intriguing as the Rolex Submariner two-tone example.The Rolex Submariner was introduced to the market in the early 1950s and was the first timepiece in the brand’s catalog to offer water resistance up to 100 meters. This depth rating would eventually be increased to up to 300 meters, where it remains for the modern versions of the Submariner that are sold today. Other notable upgrades made to the line over the past six decades include improved materials (904L Oystersteel), longer-lasting lume (Chromalight), higher-beat Caliebr 3135 perpetual movements, tougher scratch-resistant sapphire crystals, and unidirectional rotating timing bezels.The Submariner was first offered in stainless steel, then in yellow gold. The first two-tone Submariner wasn’t released until 1984, with the reference 16803. This take on Rolex’s famous professional diver introduced the line to a brand new level of collectors who sought a gold Rolex but didn’t have the budget for an all-gold timepiece. Fast forward to 2009 with the release of this article’s featured ref. 116613, a completely redesigned dive watch with an upgraded bracelet and case, a redesigned bezel fitted with a ceramic insert, and a larger display on the dial.The Rolex Submariner is a dive watch legend. From its many appearances in the James Bond franchise to gracing the wrists of numerous A-list celebrities, the Submariner has become one of the most recognizable and coveted luxury watches in the world. The line is varied and offers options in either an all Oystersteel (904L stainless steel), Rolesor (two-tone steel and gold), or solid 18k gold. Today, we will compare two of the most iconic two-tone Rolex Submariner references – the Rolex 16613 and Rolex 116613.
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.
On the dial at 12 o’clock, there is a FA Jones signaure in black, a small hand is showing current seconds on subdial at 6 o’clock. Central hour and minute hands are classic Breguet hands, which add a little retro flavor to the watch. Printed Arabic hour markers are in blue.Look at the manual winding movement through crystal back, each movement plate is carefully crafted, from polishing to chamfering, each detail is uncompromised.The leather band varies from brown, blue and black on different model. Please tell me which one you like: rose gold case with brown leather strap, blue hour markers with blue leather band or black hour markers with black leather strap.
