Why Carrera 16 CV2A80 titanium is not in the official catalog?

[Storm trooper]

Hi ,any tag owner out there owns a carbon fibre carrera 16 cv2a80.To me it is the best design (with red thread on carbon fiber effect leather) as compare to other metal bracelet. Question is how come it is not in the official catalog and confirmed it is not a limited edition piece .Hard to find in the boutique now. Any one have an answer?
