How to set the time on a flip clock

[BruceM]

I have acquired a flip clock which MIGHT be in working order, but I'm not sure.
It does flip over every minute so that works, but the manual flipping is inconsistent. Most of the time it is blocked.
I've searched for instructions on how to set the initial time on these darned devices and found precious little.
You have to set the minutes to zero before you can adjust the hours etc etc
So please point me at some instructions in plain English.
My clock is a Twemco BQ-50 which I guess works the same way as hundreds of others.

thanx

Hey Bruce, Mackey touched on setting the time on a Twemco in this video:

Not the same model but might be close enough to be helpful.

Hey, I remember that Clock!
I actually just dug it out of cold storage and have in up on a shelf in the half bathroom now.

Something makes me think TWEMCO would not approve of my post.
