It is equipped with IWC's self-made 32100 movement. The movement uses an anti-magnetic silicon material escapement, combined with a soft iron inner case, to further resist magnetic field interference. The movement is equipped with an efficient two-way pawl winding system, which can accumulate a 72-hour power reserve in the mainspring. The watch has a black fabric strap with a sandblasted stainless steel pin buckle.Replica IWC Pilot's

The case is made of black zirconia ceramic. This material was first developed and used in watchmaking by IWC in the 1980s. Second only to diamond on the Vickers hardness scale, ceramics are among the hardest substances on Earth. Due to its lightness, hardness and scratch resistance, this material is ideal for making watch cases, especially suitable for daily use in the cockpit of jet aircraft where space is limited. In addition, the quiet matte black prevents the pilot from being disturbed by the sunlight reflected by the watch. The back of the case is made of lightweight titanium and is engraved with flying patterns against the background of the Ace of Spades.

Super-LumiNova® fluorescent coating is a high-tech ceramic compound that works like a light storage battery. By absorbing light energy from sunlight or artificial light sources, the electrons in the material enter a higher energy state and store energy. When the electron returns to its normal state, the absorbed energy is emitted as visible light, making it glow in the dark. The material can absorb and release light energy repeatedly indefinitely without aging or reducing its ability to store light.

The most eye-catching highlight of the watch is the full luminous white dial. This dial was developed by IWC for the "Ace of Spades" special edition, and the manufacturing process is exquisite and complex. First, the advanced Super-LumiNova® fluorescent coating pigment and binder are mixed, poured into a circular mold, and then hardened through a specially developed curing process, making the material as durable as ceramics. The formed solid dial is then fixed to the soft iron dial blank. Finally, black scales, numbers and badges resembling the 'Ace of Spades' in playing cards are printed on the dial. In the dark room test, the dial can continuously emit bright green light for more than 23 hours, bringing the watch's readability and night visibility to a whole new level.

The “Professional Pilot’s Watches Program” initiated by IWC is specially developed for pilots flying high-speed jet aircraft, fully meeting their stringent requirements. Pilot's Automatic 41 Black Aces Watch IW326905 is inspired by one of the ace flying teams (in English, Black Ace is the Ace of Spades in poker, which can be extended to "ace").Replica IWC Watches
