As previously mentioned, the case also received a ceramic “Cerachrom” insert, which is virtually scratch-proof and will not fade and lose its vibrant color like aluminum. The ref. 116613 is also available with Rolex’s patented “Chromalight” lume on the dial, which offers a bright, blue glow for up to 8 continuous hours (as well as larger plots). Similar to the ref. 16613, the newer model Submariner Rolex 116613 is also available with either a blue or black dial and bezel combination. However, the Serti dials on the 116613 only come in blue or black (rather than champagne or silver), and do not feature sapphires set into the markers on the 6, 9, and 12 o’clock locations. Instead, ref. 116613 Serti dials only have 8 diamonds set in them, and feature lume-filled indexes for the 6, 9, and 12 o’clock hour markers.Both the Submariner 16613 and 116613 run on the Rolex Caliber 3135 perpetual movement with a 48-hour power reserve. However, the version of the Cal. 3135 inside the newer ref. 116613 is fitted with an upgraded paramagnetic blue Parachrom hairspring for better resistance to shocks and temperature variations.
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.
