Carrera CS3110 Case back White Lettering

Hi everyone. I’m new to the forum and just had a quick question. I tried to find the answer, so if I missed it please forgive me. I’m on the hunt for a CS3110. I’ve noticed some case-backs have vibrant white lettering, while most just have the no color engraving. Is the white lettering normal/original? 2nd question: Has anyone personally seen any fakes on the market floating around? I’ve read these haven’t really been replicated so I’m feeling safer buying one, given I’m not too knowledgeable on older Heuer stuff.
Thanks for any information!

I don't think it's white, just light reflecting in different ways in the photographs. I've never seen one with white lettering on the caseback, and don't think paint-fill on a caseback would be a good idea anyway.

Oh, and never seen a fake of this model. Fakes of Tag chronographs tend to be much less convincing than the three-hand models anyway.

The lettering isn’t white, it’s just way that the light is reflecting as previously mentioned. I’ve never seen a fake one of these.
