Tissot PRX Powermatic 80 Movement Removal & Reinstallation

In this video, I remove and reinstall the Powermatic 80 movement from a Tissot PRX. This is part of my ongoing journey learning mechanical watchmaking from the ground up. I document the full process — carefully, step by step — focusing on understanding how the movement is secured, how it sits inside the case, and how everything aligns during reinstallation. No shortcuts. No rushing. The Tissot PRX Powermatic 80 is a modern automatic movement with an extended power reserve and a compact case design, which makes movement handling and positioning especially important. On this channel, I: • Disassemble and reassemble mechanical movements • Attempt restorations and repairs • Share mistakes and corrections • Test timing and performance • Study mechanical theory in practice This is not a master watchmaker’s channel. It’s a bench journal. Precision over speed. Understanding over shortcuts. One movement at a time. --Caliber & Craft
