How to Swap a Seiko Watch Crystal

This video goes over how to swap a Seiko friction fit crystal, specifically on a Seiko 7N43-9070. I use two types of presses in this video, a lever press to remove the crystal and reinstall the bezel and a screw press to install the new crystal into the bezel. The crystal used for this specific watch in the video is the 300P03LN03 but there are other compatiable crystals for this model. Off camera I did also change out the gasket that the crystal rests in when it is in the bezel (no special tools needed to install a gasket they just slide in).
