Case is made of 316L stainless steel and brushed. It is measured to be 40mm in diameter. From side view, the case has a nice arc degree, so this ensure the watch could fit your wrist perfectly. Crown uses screw-in construction like genuine and there are delicate engravings. On solid case back, there are six notches that are exclusive to IWC Mark series. Great polishing work you can see on the back. Opening the case back, you will find a soft iron cage that is antimagnetic between case back and movement, which is the same as genuine Mark XI. By the way, the bracelet is polished beautifully. The front face is brushed while its edges are polished. There are also “IWC” on the front and other engravings on back side. The buckle pin is polished. Now at last, the watch specification will be listed below:
Initially only available in White or Yellow Rolesor (Rolex’s name for a combination of steel and gold), they were just successful enough for an all-steel reference with a smooth bezel to follow in 2012.Yet it seemed to be too much of a design departure for either the traditional customer base or else the brand itself, and the Datejust II was discontinued by 2016. The Datejust 41 replaced it as a very much a scaled-up version of the 36mm piece, with the classic dimensions intact.But there was always a relatively small but enthusiastic audience for the DJII, as decidedly masculine a dress watch as you are likely to find. Issued with a range of dial options (although, strangely, only ever produced on the Oyster bracelet) it offers plenty of choices and is the ideal model for a larger wrist.Rolex is very proud of their patented Cerachrom ceramic alloy, and rightly so. Scratchproof, fade-proof, nigh on unbreakable, it is the perfect material for the brand’s bezels and it has been rolled out across most of the tool watch collection. On the Daytona, it is fitted to models forged from platinum, all three flavors of gold, and the only two steel pieces left in the contemporary lineup – those lusted after models which are more difficult to get ahold of than a Wonka factory golden ticket.But Cerachrom is a fairly new invention. Previous iterations of the stainless steel Daytona have always had steel bezels, something no longer obtainable if you are buying brand new. The last reference to have one was the ref. 116520, which ran from 2000 to 2016, and was the first Daytona to house Rolex’s own in-house chronograph movement, the Cal. 4130.
The GMT Master II ref. 16710 is one of the most iconic and influential examples of the brand’s multi-time zone pilot’s watch. It brought an upgraded case and movement to the line, making it a huge success and leading to its impressive production run of almost twenty years. The ref. 16710 was then replaced by the ref. 116710 in the late 2000s as a completely new generation of Rolex GMT-Master tool watches began to make an appearance with a brand new case and bracelet design, improved materials, and a new movement.Rolex developed the GMT-Master in the early 1950s at the request of Pan Am Airlines. Its release came during the dawn of international flight. The famous air carrier required a dual-time wristwatch to issue their pilots, and the GMT-Master was born. The GMT-Master II was released a number of years later in 1983 with the ref. 16760, and brought with it independent hour hands that allow the wearer to read two time zones on the dial and a third on the bezel.The first GMT-Master II ref. 16760 featured a bulkier case and is often referred to by avid collectors as the “Fat Lady” or “Sophia Loren.” In 1989, Rolex would release a refined variation of the Fat Lady GMT in the form of the sleeker reference Rolex 16710 with a thinner case and movement. The ref. 16710 was well-received among collectors for its upgraded case and movement, and it would go on to become one of the most successful GMT-Master II models, remaining in production for nearly twenty years.A completely redesigned version of the stainless steel Rolex GMT-Master II was introduced in 2007, which meant the discontinuation of the long-running ref. 16710. The Rolex 116710 is similar in design as its 5-digit predecessor with an all-steel finish, a perpetual movement with independent hour hands, and a bidirectional bezel; however, that’s where its similarities end. The ref. 116710 is almost an entirely new watch and boasts a redesigned bezel, case, bracelet, and dial, as well as the newer Caliber 3186 perpetual movement.
About this two tone Submariner 116613LN, there are basically four factories that are making it. BP, GM, AR and Noob. Among four of them, BP is the factory makes the cheapest one. GM is a new factory, I do not know their quality. So, the last two factories AR and Noob are worth your consideration. Based on the V1 edition, this time AR factory update the bezel and dial, the thickness of yellow gold coating on case and bracelet is also improved. First, the 18K yellow gold coating, which the factory claims, is updated to be 8 mils thick. Second, the black ceramic bezel insert is also updated, the golden markers on the bezel are improved to have the same engraving depth. Thrid, about dial improvement, the golden edge of hour markers is narrowed, while the central lume part is wider, so there will be more lume coating on each hour marker to guarantee stronger and longer lume light in dark conditions.So, instead of spending $50 USD more on the 116613LN from Noob, it is better to choose this one from AR factory.I love vintage watches very much. Especially Rolex and Panerai are my most favorite.This generation’s Paul Newman Daytonas are currently flying under the radar. Yes, the Rolex GMT-Master II has already doubled in value, and is likely going to appreciate further due to Rolex carefully managing the supply of that model to the ravenous public, but only by 200%, 300%, 500%. Now, that’s not too bad at all, but the really crazy money is likely hiding somewhere in the far corner of the industry and we won’t know what it is until it’s too late to rush out, cash in hand, and “collect” it.So what should we do in the meantime? I told my little friend, desperate to see a return on his money that he should be patient. He should wait to fall in love. He should truly get to know himself before he pulls the trigger. And then, when he’s good and ready, he should buy a Rolex anyway.
