Colin from Watch off the Cuff provides a comprehensive, step-by-step tutorial on replacing a scratched or cracked watch crystal. He demonstrates the entire process using a personal Seiko 5, covering essential tools such as a crystal press, various dies, micrometers, and calipers. The video details how to measure the crystal accurately, remove the bracelet and movement, and safely press the old crystal out and the new one in. Colin also emphasizes the importance of cleanliness, specifically the use of Rodico to remove dirt from the gasket seat and ensuring the new crystal is perfectly clean before installation to avoid smudges or debris inside the watch.
