Did you catch Lewis Hamilton rocking a new IWC Schaffhausen timepiece at the Monaco Grand Prix over the weekend? We did too, and as curious watch fanatics, we couldn’t help but speculate on what exactly this stark-white timepiece could be. A new iteration of the 2022 Pilot’s Watch Chronograph TOP GUN “Lake Tahoe” edition, perhaps?
Sort of.
Earlier this week, IWC took to Instagram to reveal what its experimental engineering division, XPL, has been working on over the last few years. Introducing the new IWC Ceralume Pilot’s Chronograph—a ceramic watch, albeit a prototype, that completely glows in the dark, from case to dial to strap!

Such wizardry is thanks to a proprietary luminous ceramic technology that IWC calls “Ceralume.” This technical feat has allowed IWC watchmakers to produce their very first fully luminous ceramic watch. Building on its 40-year journey as true pioneers of engineering ceramic material within watches—ceramic is notoriously difficult to work with, you see—IWC is no stranger to such technical feats.
Thanks to the homogeneous mixing of ceramic powders with high-grade Super-LumiNova pigments, IWC has fashioned a luminous material that acts like a battery for storing light energy. Utilising the new Ceralume technology, this fully luminous concept Pilot’s Chronograph emits a bright blueish light that lasts more than 24 hours.
“With the first fully luminous ceramic case rings, we underscore our role as a pioneer and innovator in ceramic watches. The development of Ceralume took several years. The main challenges we faced were producing watch cases with maximum homogeneity and meeting our exacting quality standards,” says Dr. Lorenz Brunner, Department Manager Research & Innovation at IWC Schaffhausen.
“To achieve these goals, we engineered a ground-breaking new manufacturing process – tailored to the unique combination of ceramic powders and Super-LumiNova pigments.”
If we’re to get extra technical, the ceramic material absorbs light energy from sunlight (or artificial light), stores it temporarily, and then emits the absorbed energy as visible light—the luminous “glow” that you see below. According to IWC, this cycle is infinite and will never cause the material to age or diminish its light storage capacity.

Developed completely in-house by IWC and its Experimental Engineering Division (XPL), the patent-pending Ceralume technology will undoubtedly form the foundation of future developments and releases, with a broader commercial release imminent.
