Replacing the crystal on a Seiko 7549-7010 300m Tuna

I needed to change the crystal in my Seiko 7549-7010, so here's how I do it.
Since the crystal needed to be swapped, I did a complete case rebuild (minus crown since that's good) start to finish. Things to look for, how I use silicon grease on cases, tips, all that.

PSA: This video contains sub-optimal levels of editing, namely, none. No script, no planning, no real editing, nothing. Same for the sound - I forgot my microphone so if you can hear *anything* count that as a win. Even if that "anything" is tuneless humming. I did pump up the volume though. YMMV if you choose to blow part of your life on this. No Refunds. Enjoy!
