: Just to clarify what I mean; the early Carrera's have bridges
: signed 'ED. HEUER & CO SA', the later ones 'HEUER LEONIDAS
: SA'. However, the font and engraving looks a little different on
: this watch to, for example, the one in this article:

: We've also seen the same font/engraving on questionable watches on
: eBay - usually appearing on inner casebacks and bridges. My
: unqualified(!) suspicion is that this bridge has been replaced
: to make the watch appear to be an earlier piece.

: It might just be the photo/lighting/angle though. Someone more
: qualified than me will, no doubt, be right along to put me in my
: place and allay my fears. ;)

I would second this, the differences are subtle but the engraving on the bridge does not appear to be the same as the one posted in the article. I would not consider myself an expert by any means but that is the first thing that I noticed.
