An Elegant Watch… A Grueling Repair | Longines Ultra-Chron

This Longines Ultra-Chron is an elegant, high-quality watch that looked like it should be a straightforward service. But once I started working on it, the project quickly proved to be far more complicated than expected. What appeared to be a routine repair turned into a series of unexpected problems that made this Ultra-Chron anything but simple. The Longines Ultra-Chron is a high-beat movement known for precision and quality, but this example had several issues hiding beneath its refined exterior. In this video, I take you step by step through the full disassembly, diagnosis, cleaning, and rebuild as I work to bring this classic watch back to reliable running condition. If you enjoy vintage watch repairs, detailed watchmaking work, and the occasional challenging project, this is one you won’t want to miss. 👍 Don't forget to like, comment, and subscribe for more watch repair projects and behind-the-scenes stories! 🎩 Instagram Hat Giveaway GIVEAWAY DETAILS: I'm giving away a brand new Weekend Watch Repair hat on Instagram!
