Frontal crystal is made of sapphire, the surface has a layer of anti-reflective coating that looks a little purple when seeing at a certain angle. This features on the replica is 100% the same as genuine. Black dial does not have special points, like other diving watches, it has a strong lume effect. See the dial lume picture below, you can see there are three different lume color on the dial. The skeletonized design of hour and minute hands is also my love about the replica. Central second hand has a red tip that just echoes with the red “Seamaster” lettering below OMEGA LOGO. I have to say the skeleton design of hands is a little similar to the feel which the bracelet gives to me.Finally it comes to the band, which is fully brushed stainless steel bracelet. I can not find a professional word to describe the bracelet, but actually I find its design perfectly matches the whole theme of the replica watch. I can not find any other bracelet on this watch that will have such a design similarity to its hands and bezel. Perhaps a vintage nato strap will also work fine.The bracelet looks a little loose on my wrist, but the watch body seems to be very nice, I love big watch.
The Oyster case was an innovation of its time when it was developed by Rolex in 1926. It ushered in a brand new era of durable, everyday watches that could be worn during almost any activity without damaging the internal movement. The Submariner takes the design of the Oyster case one step further and increased its waterproofness up to 300 meters/1,000 feet.The ref. 16613 features a standard 40mm case in highly corrosion-resistant 904L stainless steel. An 18 karat yellow gold screw-down crown and unidirectional bezel accompany the case, giving it a desirable two-tone design. The dial and bezel set are most commonly available in either black or blue, with some examples of the gem-set “Serti” dial (either champagne or silver in color and set with diamonds and blue sapphires) also available on the secondary market. Depending on the year produced, the ref. 16613 also features either a holes or no holes case and either Tritium or LumiNova used for the luminescence on the dial and hands.Regardless of the year of production, all two-tone Rolex 16613 Submariner watches are powered by Rolex’s trusty Caliber 3135 automatic movement. The 31-jewel movement beats at a rate of 28,800bph and includes a date complication, a 48-hour power reserve, automatic winding technology, and a sophisticated Breguet overcoil balance-spring. The movement has been a fixture in many Rolex wristwatches for more than three decades, and for a good reason. The Cal. 3135 has proven itself to be an accurate and robust movement, which can deliver decades of reliable performance if properly maintained.
Second, the movement vibration frequency is 28800vph, what shocked us is its chronograph function. Using 7750-2 automatic movement, almost has the same capability as original. It has insurance to be accurate in travel time. So you don’t need to confuse about this problem. With thin and long hand, compared with its big dial, it is more generous in the whole style. Its chronograph counter subdial is located in the place of twelve o’clock, and small second hand stays in the place of six o’clock.Third, the replicas uses leather strap, giving us a good touch feeling with such material. And considering we may has different dressings with various styles, this replica can provide two kinds of straps so that you can change as your like. You can change as domestic alligator strap or America alligator strap. The black leather strap matching with the fold-over clasp, can satisfy your requirement about comfortable feeling and convenience. When we observe it carefully, we see a big IWC logo in clasp clearly. Most of all, the replica is so nice in appearance with any details, you may almost can not find out its difference with the original. And its powerful capability as well.
