Dick,
Apparently, he didn't get his information from a trusted source... :)
L 189 clearly shows up on the movement, plus absolutely no questioning this seller.

Thanks
Bryce

: I'm wondering where you have gotten your information. As the seller
: of this watch, and also the original purchaser and only owner of
: this watch, I can tell you that it is all original -- just as it
: came to me from Heuer - New York. It is a Carrera 45 Dato, and
: in the OTD chart listing this model, it shows that all of the
: Carrera 45 Dato models came with the Landeron 189 movement, just
: as this one has. The only part changed on this watch is the
: crystal, the rest is just as original.
