IWC Big Pilot's Watch Perpetual Calendar Edition Racing Green IW503005(Replica IWC Big Pilot's, the new special limited edition watch uses a matte black Ceratanium® case with a vibrant "racing green" dial. The case has a diameter of 46.5 mm and a thickness of 15.5 mm. It is equipped with a screw-in crown, a double-sided anti-glare sapphire crystal and a see-through case back. It has a water resistance of 6 bar (60 meters). The mirror assembly is stable and can withstand sudden drops in air pressure.

The "racing green" dial is decorated with contrasting white markings, combined with gold-plated hands and moon phase discs. The hour and minute hands are coated with Super-LumiNova fluorescent material, and the calendar hands have a red tip to ensure clear and easy reading. Although the functions are complex and diverse, the layout is uniform, balanced and coordinated, which is one of the main advantages of the perpetual calendar module developed by Kurt Klaus.

 There is a date display and a power reserve display at 3 o'clock, and a month display at 6 o'clock. The day of the week and the small seconds share the small dial at 9 o'clock. There is a dual moon phase display at 12 o'clock, which accurately and vividly shows the different moon phases seen in the southern and northern hemispheres. A major feature of IWC's perpetual calendar mechanism is that "one-key adjustment" can be easily achieved through the crown. There is also a four-digit display window between 7 o'clock and 8 o'clock, which can be used to display the year.

This watch is equipped with IWC's self-made 52615 movement, which is assembled from 386 parts, contains 54 jewels, and vibrates at 28,800 vibrations per hour (4 Hz). The 52615 movement adopts the Bieleton automatic winding system, which is an efficient two-way pawl winding system, equipped with ceramic components to reduce wear. The oscillating weight has been hollowed out and decorated with an 18K gold badge. The full chain can provide a long power reserve of 168 hours (7 days). In addition, the movement is also decorated with exquisite Geneva pattern and fish scale pattern. Replica IWC Watches
