Hi m8,
I've got one of these (well i think i have - its been at the watchmakers getting the hands fixed since January!) and its great.
The ebay auction just doesn't do it enough justice - whatever possessed the seller to paint the bezel beats me! :-)
Some better images and more info (in French) here - http://www.invenitetfecit.com/modeles/page-enicarjetgraph.html
I came across mine while searching for a gmt hour wheel for my own 2446c and discovered the movements are both v/j724.
I think it feels a bit more robust than the Heuer and the extra timezone indicator is pretty cool.
Interesting fact I think enicar is derived from racine spelt backwards.
