Above are the official specifications.This ZF‑factory Big Pilot houses a Seagull movement with nearly five‑day power reserve, perfectly replicating the original genuine power‑reserve indicator. The watch is 1:1 moulded after the original. Both numerals and hands are fully luminescent. The threaded ring of the power‑reserve display is exquisitely finished and features a deeper shade of blue than the main dial.

For all IWC Le Petit Prince special‑edition watches, the numerals feature a 3D design. Just like the original, this replica delivers a more three‑dimensional dial.

The leather strap of the Le Petit Prince special edition is extremely soft, and the stitching craftsmanship on the strap is excellent.

The case‑back of the Le Petit Prince special‑edition watch features a unique engraving depicting a young boy.

Almost every IWC watch comes with a blue anti‑reflective coating, a design detail favoured by the brand. However, you should not fixate on this feature. Many watch models from Cartier, Omega, Rolex, Panerai and other brands do not have a blue‑tinted coating at all. A blue coating does not automatically mean better quality. Some smaller manufacturers will add a blue film to watches whose original versions have none, simply to satisfy buyer expectations. You should view this feature rationally. It is no high‑tech feature; the only real consideration is whether to stay faithful to the original design.

Now let’s take a look at the standard‑version IWC Big Pilot. The differences lie in its black dial, black leather strap and distinct case‑back engraving. Its dimensions, thickness, power reserve and movement remain identical.

Finally, we will introduce the Muhammad Ali special‑edition watch. It is fitted with red hands in its colour scheme, which symbolise boxing gloves. The inner side of the strap is also bright red, and the case‑back bears an engraved signature of Muhammad Ali. Below is an excerpt introducing the legendary story of this boxing champion: Muhammad Ali‑Haj (January 17, 1942 – June 4, 2016) was a world‑famous American boxer born in Louisville. His birth name was Cassius Marcellus Clay, Jr. He started his boxing career at the age of 12. In 1964, the 22‑year‑old Ali defeated Sonny Liston and claimed his first heavyweight championship title. He beat Liston again in the same year, ushering in the Ali‑era of professional boxing. Over the following 20 years, Ali won the heavyweight championship 22 times. He retired from boxing in 1981. Later in life, he was diagnosed with Parkinson’s disease.
