Aug 30, 2022DIY Watch Club
In this video (Part 1), we'll discuss in detail how to attach GMT, hour, and minute hands onto your watch with basic equipment and how to choose the correct tool for hand installation. We have used a Seiko NH34 aka 4R34 as a demonstration, but the principle should work for other GMT movements. This video is designed for beginners so we'll cover quite some basics.
