This Watch Could Kill You! Restoring a Jardur Chronograph with Radioactive Lume

WARNING: This is one of the most dangerous restorations I've ever done! In this video, I take you inside the restoration of a rare vintage Jardur Chronograph equipped with the legendary Valjoux 71 movement. But this isn't just any restoration—this watch hides a deadly secret. The lume inside the hands is radioactive, making every step of this restoration extremely delicate and risky. You'll see the full step-by-step disassembly, inspection, cleaning, lubrication, and reassembly of the Valjoux 71 chronograph movement, known for its complexity with minute, second, and hour totalizers. This kind of vintage military-style chronograph requires the highest level of care—not only because of its mechanical intricacy but also due to the serious health hazards linked to the radioactive lume material, which can be deadly if mishandled. In this video, I show you how I safely manage the risk, protect myself, and bring this beautiful and historic chronograph back to life, making it work like new. If you love vintage chronographs, rare military watches, or want to see what it's like to work on dangerous timepieces—this is the video for you!
