Having trouble digging up a parts list for the 6139-6022 "Pulsations", but I believe that the original parts number for the crystal is the 350T02ANS. Is this correct?

Hi I've owned Seiko Bell-matic's since 1976 or so. I've had two (so far) and I love them. I'm hard on them and have to replace the crystals and wonder is any tougher ones can be had. Thank you Tony

To encourage everyone here, I took pictures while doing my first crystal replacement. I have no experience with this, so maybe I overlooked some things - please reply with notes on how to improve my process. This "tutorial" is also available as an album on imgur: http://imgur.com/a/GnFY0 I...
