Good point Mark. I am a little more hazy about dates when it comes to the no name Heuers before the famous Carrera, Autavia etc.
I love the 2444 though, I'll do a post with some photos of the ones I have in a couple of days, maybe you can add some details.

: Both nice, but wouldn't we be talking '60s for the one in the
: 2444-based case? That watch is a child of the (early) 60s, so I
: would put this one in the same timeframe, making the watches
: more or less book-end the decade. I'd expect a 50s watch to be
: in the 2443 case that preceded this one, at least by the late
: 50s - at the start of the decade they were probably still using
: the (original, non-Carrera) 2447 case.
