Hello, I am trying to verify if my new Ti bracelet for my Defy Classic is authentic or not. Are there any distinct characteristics? Were there two different Ti bracelets produced, because I see YouTube videos with two slightly different Ti bracelet models or variations in the video reviews. Are the Ti bracelets "Star" and "Zenith", laser engraved or stamped. I bought it on Chrono24 from a "private" seller. Thank You, Leopold
