Hi guys I wonder if anyone may be able to help me - I recently got myself a Heuer Monza. Not the best watch in the world but nice looking and pretty accurate. Anyway my question is this ...my watch is a year or so old and has Heuer on the face and buckle new watches have TAG Huere on the face and a TAG buckle - I know why this is but I saw post on ebay a while ago suggesting that this makes the older watch more valuable? Are there any other differences inside the watch? Thanks Neil
