Please help identify this Waterman.

This pen was passed down to me a bit over 17 years ago after my father died. I know he used it to sign important documents and vividly remember opening his desk as a child and playing with it, this would have been in the 90's. I'd suspect it is from the 80's but I am not quite sure. As you can see it has a hexagon and "PARIS" on the cap and below that on the pen itself are the words "WATERMAN" and "FRANCE". I've never felt a more well constructed pen and the personal history of it makes it priceless to me.

 

Can you identify it and estimate a year it could have been purchased? What is something like this worth just out of mere curiosity? Thanks <3.

 

Also as an aside can anyone recommend top tier cartridges to use with it? I'm primarily using pilot g2's because they are so easy to come by but perhaps a pen like this deserves better! Also please excuse my terrible handwriting!

Waterman L'Etalon rollerball. No longer a current model but was nearer the top of the range than the bottom in it's day.
