Back in May of 2024, IWC equipped Lewis Hamilton with every five-year-old boy’s dream watch. The Pilot’s Watch Chronograph 41 Ceralume, which looks white at first glance, is actually made of ceramic powder infused with luminous pigment, so the case, dial, and white rubber strap doubled as a night light. Unfortunately, like many pieces worn by Hamilton, it was just a production piece that wasn’t available to the general public.
Collectors’ patience was rewarded earlier this year, though, when IWC debuted a commercial—and more complicated—version of the technology in the form of the Big Pilot’s Watch Perpetual Calendar Ceralume. Limited to 250 pieces, it has already found itself on the wrist of one mega-collector (and former IWC ambassador) in the form of Tom Brady, who wore one while on vacation with his family in southern France.

This IWC has been one of the breakout hits on watch social media this year. The effect of the entire piece breaking out into a neon blue glow whenever it enters the dark is quite a stunt. This watch is a statement piece unlike any other statement piece. While many watches at Brady’s level earn their keep with endless complications, stupifying diamond setting, or both, IWC developed a watch that steals attention unlike anything else at the horological buffet right now.
Of course, being a Big Pilot’s Watch, the thing lives up to its name. Measuring 46.5mm, it only looks manageable because Brady is 6’4”. Being made of ceramic, however, it’s not nearly as heavy as one might imagine, and its heft is further mitigated by its white two-piece rubber strap. The movement produces all sorts of inten—a moonphase, date/power reserve, month, and running seconds/day—plus a small aperture for the year—but pales in comparison to the story behind the watch’s insane case.
