Hello all! I am wondering about dial text on Ultra Thins from the '60s and '70s, specifically 6351s. Below are two pics. One dial reads "Vacheron & Constantin," "Genève," and "Swiss." The other dial reads "Vacheron Constantin," "Geneve," and "O Swiss O." I have seen the former far more frequently than the latter, so I am wondering if the second example is either fake or a redial. Any input would be greatly appreciated. Thanks.
