If the IWC brand is an absolute reference in the world of “classic” pilot watches, it also knows how to evolve in a more innovative and contemporary register. Proof of this is its new gem spotted on Lewis Hamilton’s wrist: using Ceralume technology, this concept is the first fully luminous ceramic watch!
What is Ceralume technology?
We already knew about the luminescent coatings on the indices and hands of watches, the famous Super-LumiNova. Some brands even go so far as to overdo it, like Yema with its Superman Maxi Dial Full Lume and its dial entirely covered with Grade A Super-LumiNova® BGW9.
But IWC Schaffhausen has decided to go even further by unveiling a proprietary luminous ceramic technology, named Ceralume®. The result of several years of research conducted by the brand’s XPL engineering division, this technology is not limited to the dial, but allows for the production of fully luminous ceramic watch cases for the first time. Without going too much into technical and scientific details, it can be said that this innovation is based on a patented process where ceramic powders are homogeneously mixed with Super-LumiNova pigments, this famous material that acts as a battery to store light energy.
The manufacturing process of Ceralume® is complex and requires precise engineering. Ceramic powders and Super-LumiNova pigments are combined via a particular ball milling process to ensure a perfectly homogeneous mixture. This step is crucial to avoid any accumulation of particles and ensure the uniform luminous quality of the final product. According to IWC, the treated ceramic is capable of emitting a bluish light for more than 24 hours, as demonstrated by darkroom tests.
IWC transforms its pilot chronograph into a luminous watch
With this innovation, IWC Schaffhausen reinvents its famous pilot’s chronograph by integrating Ceralume® technology. For the rest, the design of this watch is based on the Pilot’s Watch Chronograph 41 model, which it retains the clean lines and ergonomics of.
But rather than the usual steel, this “concept watch” stands out for its ability to glow in the dark, thanks to its luminous ceramic case, its brass dial sprayed with a Super-LumiNova solution, and its white rubber strap which is also enriched with luminescent pigments.
The innovation in ceramic materials at IWC isn’t something new. As early as 1986, the brand launched the world’s first wristwatch with a case made of black zirconium ceramic. Since then, IWC has continued to push the boundaries by introducing advanced materials like silicon nitride ceramic and black boron carbide, one of the hardest materials known.
And since ceramic has (re)become essential in watch collections in 2024, this material has recently entered the Top Gun range of IWC, with colorful high-end watches! Although not yet on sale, the new ceramic Ceralume® model was seen on the wrist of Lewis Hamilton at the F1 Grand Prix in Monaco, with IWC being a sponsor of the Mercedes team.
