My first Zodiac! - Zodiac Glorious- any idea of it's date?

[TheWatcher]

I'm only on the site about 3 weeks as I have only bought my first Zodiac watch. A friend of mine has been bugging me to keep an eye out for a good but well priced Sea Wolf and in my search I came across this beautiful Glorious. I love 1950s/ early 60s simple elegant style, so for the money and it's condition I couldn't let it go even though I had no intention of buying more watches! 

Can anyone give me an idea of it's date of manufacture?
All comments and/ or criticisms are welcome as I am totally new here and new to the world of Zodiac watches.

My Zodiac Glorious:

Case serial number: 1235343
