Full restoration done! 1930s-early 1940s Landeron Hahn 45 minute monopusher chronograph. Landeron Hahn caliber 2, column wheel design. This beauty is huge too, almost 40mm in diameter. I had to put many hours into this job, including extensive corrosion removal and part refinishing, custom made springs to replace the worn out ones, hammer adjustments, hairspring and balance repairs, countless snapped screws repaired, dial repairs, case repaiea minute jumper brazed, etc etc, one of the biggest jobs I have done for a customer. But wow! What an awesome result. Everything works like new and it runs surprising well. A 85+ year old watch that's now ready for daily wear again in 2025 ππππ Added a little jazz music for period appropriateness π
