Reviving a Dead Jaeger-LeCoultre Triple Date Moonphase | Caliber 901

This Vintage watch Jaeger-LeCoultre Triple Date with Moonphase was in terrible shape. It arrived from a subscriber in the Netherlands — completely dead. The watch wouldn't wind, the moonphase quickset didn’t work, and even the crown was stuck. From the outside, it was dirty and motionless... and inside? Things were much worse for this restoration. As soon as I opened it, I found a rusted, non-functional Jaeger-LeCoultre Caliber 901, with corroded screws, oxidized parts, and layers of grime. Some components were literally disintegrated by rust. In this video, I take you through the full service process of this complicated and elegant movement: ✅ Disassembly ✅ Cleaning and rust removal ✅ Inspection and lubrication ✅ Reassembly and adjustment ✅ Final results on the timegrapher This Triple Calendar Moonphase movement from JLC is a true piece of haute horlogerie — and bringing it back to life was both a technical challenge and a pleasure. 🔔 Don’t forget to like, comment and subscribe if you love vintage watchmaking content! 🧰 I use tools from Maison Vénus, my trusted partner for high-quality watchmaking equipment. 📲 The restoration Reels will also be posted soon on Instagram — stay tuned! 💬 Would you have dared to restore this kind of rusted movement?
