Not a Heuer for me, never seen anything like it. We've seen quite a few of the French-made and late economy models by now but this is the first one resembling this. I'd wager if we look hard enough, we'd turn up more examples of this watch wearing another manufacturer's name on the dial.

On a different note, Google translates part of one of the replies as:

Same story for the Mappamondo and Heuer caliber 7736 with three counters, first discussed as "doubtful", and now accepted in the convention.

Who is accepting Mappamondos as genuine Heuers and since when? It's not something I'd agree with.
