Most of the new TAG reps from the WAK2110 to the 500m A.Racers are spot on !
I know this info isn't for the Carrera model you seek but one would assume they've pretty much nailed it when it comes to TAG
The WAK2110 with prof AR and mounted on the gen BA0830 was good enough to me for me to sell the gen.
Aside from the TAG logo on the dial, the WAJ2110 500m A.Racer is a dead ringer as well...dropped the rep and broke it FUBR'd so picked up the gen.
Loved it so much, had to have to gen WAJ2111 silver dial.
But was able to confirm on the 2110, aside from the HEV being there for looks on the rep ( no inner he valve at all ) the rep case is 100% gen spec.
The gen and rep crown, crystal, bezel, case back, mvt ring and mvt. are all interchangeable....rep case "is" spot on.
And of course the gen BA0830 bracelet as well as the FB3141 SEL's for the gen FT6015/FC5040 rubber with deploy fit the lugs spot on.
Gen TAG spring bars fir perfect too....and I personally swear by gen spring bars whenever possible
Granted very nice, serviced pre-owned gens (complete boxed sets) of both the WAJ2110 and 2111 can be found for 1100.00-ish and 1500.00-ish it's nice to know the reps are equally as nice looking.
