Complete Restoration of a 1940s Longines 9L – Stunning Vintage Movement!

In this video, I take you through the full watch restoration of a stunning vintage Longines wristwatch, powered by the legendary manual-wind 9L movement. 🕰️ This timepiece dates back to the late 1930s to early 1940s, and it came to me in remarkable condition — complete with the original Longines box, guarantee papers, bracelet, and signed buckle. The video covers: - Opening the case and inspecting the beautifully preserved 9L movement - Removing the hands and dial with care - Examining the bimetallic balance wheel, designed to compensate for temperature variations — a hallmark of high-end horology at the time - Noting some issues like excessive gain and slight endshake on a few jewels - Beginning the full teardown and service process, including oiling, cleaning, and adjusting 💡 The Longines 9L is a slim, elegant caliber that showcases exceptional finishing for the period — no shock protection, but excellent mechanical design and chronometric quality for its time. If you're a fan of vintage watch restoration, historical movements, or just love seeing mechanical beauty in motion, this video is for you. 🛠️ Subscribe for more restorations of vintage Swiss watches every week! #Longines #WatchRestoration #VintageWatches #ManualWatch #Longines9L #Watchmaker #VintageLongines #MechanicalWatch #Watchmaking #SwissWatches FWC Website: FWC Website: https://french-watch-collector.myshopify.com/ Follow me on Patreon: https://www.patreon.com/FrenchWatchCollector Please Subscr
