Set up and operation of Citizen BL5400-52A (E820) Eco-Drive Watch - KS #20

This is a re-run of my earlier review of my Citizen Eco-Drive (Model BL5400-52A with E820 movement) watch using all those fantastic functions it has - a perpetual calendar (which means there is no need for adjusting a date every other month), chronograph, dual time, alarm and a slide rule, which was the main reason why I purchased this watch in the first place.
For some reason my original video (recorded back in 2018) has disappeared on me. Don't ask me why - I have no idea. I asked U-Tube to help me restore it, but it is yet to be seen, and in the meantime I offer you this re-run, as I happened to have a copy of it.
Some people may say it is too complicated to set this watch up. I would not say that. I was able to figure this out after reading its manual and in this video I demonstrate how it's done. I will even show you how to use a slide rule here.
