Welcome to my watch repair channel! In this quartz wrist watch repair tutorial we disassemble and repair my 1978 Heuer 8440 quartz dive watch that I’ve had since high school, which hasn't run for over 30 years! You’ll see the quartz watch movement explained, and you’ll see a variety of watch repair tools and how to use them.
I’m just starting out on my journey into wrist watch repair and watch restoration (horology), and I hope to educate and entertain in this series of watchmaking video tutorials for beginners.
