Could you help me identify this Waterman

I just bought this lovely minimalist pen that, at first glance, could be mistaken for not being a Waterman!

There are barely any marks identifying it at all.

The cap bears an 80's style Waterman's imprint in the steel (and made in France) and the only other identifying mark is on the C/F style squeezy converter inside.

The pocket clip is a plain shiny rectangle. No embossing, imprints or cutouts at all.
Both ends of the pen are a featureless, perfect dome with absolutely no indents or rings.
The section is plain black plastic with three raised rings, just like the Cotele.
The nib, as you can see in the image below couldn't be any plainer.

Don't get me wrong - I love this pen. It's exactly the kind of understated design that I adore but I'm stumped as to what it is.

Show the clip straight on, please. It might give a better idea of what make of pen it is.

Looks like a Waterman Goutte, but I just googled it and the clip is diffetent.
