In trying to determine which came first, let's see what we can learn from the serial numbers. Post watches and serial numbers here, or send them to me by e-mail (of you prefer to keep them private).

Interesting to notice these distinctions!!

: Hi all,

: I was a real watch day for me. First a visit to the Rikketik Used
: Watch Fair in Holland ( where I met Abel in his constant quest
: for Heuer). Few Heuers. Saw a 2446 Autavia second genenation
: case and an 1533B Monaco. Abel also saw one or two manual Monaco
: with dodgy dials.

: Then at home, I looked for a comfy chair near the window ( sun was
: shining nicely), put my legs up and went enjoying the Bonham
: catalogue. I think it's one big advert for our hobby and has
: been set up very tastefully. Can't wait until the 15th!

: When looking at the two different 3147 Dato Carreras with black
: dial and date aperture at 9 and comparing them to my own 3147 I
: noticed two differences. The same differences were confirmed by
: comparing them with the photos on the OTD galery.

: Two differences; one version has a date window where the internal
: "window pane" is white, the other version has a black
: one.
: Other difference between the two types. One has the "T"
: over "swiss' the other doesn't.

: Is anyone already aware of this,and, can we judge which type was
: earlier? I have the one with the black window pane and incl. T.
: Other questions for how long have these versions been produced?

: Thanks
