If you have a vintage Rolex Datejust manufactured prior to the introduction of Caliber 3035, then your particular model is a non-quickset Datejust. To set the date and time on a Non-Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case.Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic movement).Pull the crown out to the last notch.Rotate the crown to advance the timekeeping hands. Keep turning until the correct date appears in the date window. When the correct date appears, you are now in AM hours; now set the time accordingly taking into consideration if it is currently AM or PM.Push the crown all the way back in and screw it down to the case.To set the date and time on a Quickset Rolex Datejust, follow these steps:Unscrew the winding crown by turning it counterclockwise until it releases from the case Turn the crown clockwise around 25 times to manually wind the watch (it’s always a good idea to hand-wind the watch while setting it even if it is an automatic)Pull the crown out one notch to set the date (the timekeeping hands will continue to run in this position).Rotate the crown to adjust the date. We recommend setting the date to the day before today.Pull the crown out to the last notch to set the time. Rotate the crown to move the hands past midnight so that today’s date appears in the window. You are now in AM hours; now set the time accordingly taking into consideration if it is currently AM or PMPush the crown all the way back in and screw it down to the case.Always remember to keep the winding crown on your Rolex watch screwed down onto the case if you not adjusting the time and date to protect the watch from moisture and dust. Also, never unscrew the crown if you are in or around.
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.
Second, the shape of the hands, especially the propeller-shaped end of the central second-chronograph hand is made correct.The final thing you concern about is if the replica watch has a full chronograph function. I must say yes. The watch is equipped with the most widely used Asia Valjoux 7750 movement, you can operate the chronograph buttons like you do on a genuine. Thanks to the solid case, Z factory did not make too much modification on the movement, so it could maintain a high stability of the original movement.It is a new arrival, but Z factory did not raise its price, it is sold at much cheaper than other Spitfire watches, so I recommend it if you are a pilot watch fan of IWC.
