Here is my Zodiac that I believe has the same case as the later Carrera, Its chrome plated though unlike the Heuer in stainless. I have not seen any other Zodiac, Tradition or other poor mans with this style case. So certainly a cheaper model due to materials used. As to who assembled it, I can not say, only that they went to a lot of trouble to emulate the Carrera. Yes Jeff I agree the community has handled this members assault very well. I my self was some what shocked at the original posting and really wondered what was his purpose. I'm still puzzled ! Perhaps he could explain his some what aggressive attitude.
