Seiko Production Dates

Some of my Japanese watch books have charts with production dates and I have now managed to translate a few of the different charts. For consistency, I have not made any changes, even when information in other places indicate that some of the dates may be wrong. Also, the charts note that end dates are harder to establish than start dates.

Hi:

You have an interesting blog. I like one of the Citizen watches on it, but I'd like to know more information about its make and model.

Here's your description of it

"Alarm

In the late 50s, Citizen purchased / licensed a Schild/Poljot alarm movement and continues to make alarm watches with this movement until the late 60s."

The watch you have in the photo below this description has a brown band and a silver and black face. What make and model is this type of watch specifically? And what year did it come out?

I apologize if it's already clear in your description, but I'm unsure about how to interpret the information.
