No they are not. See the pictures of 3 Montreal I posted earlier. The rarest of the Montreals is the Gold one with gold plated case, gold dial, gold indice, gold pushers and crown. I have two Black dials, one white dial, one blue dial (correct) which is having the movement repaired, and the gold dial. I have posted the a black, white and gold to the Forum. Of course all NOS Heuer are desirable and being NOS should have the Reference number and sn between the lugs. If they are NOS and don't, then something is wrong. I have purchase dog Montreal strickly for the movement parts. I have also done this with Autavia. These two Heuer models do have rare models within the group but not all of them are rare. Charles
