If you are anything like us, and you are tired of overdone 3D “computer-animated” watch videos, then you will love this “real-life” three dimensional introduction to the new A. Lange & Söhne 1815 Tourbillon. This amazing high-definition video uses close-up macro photography to highlight the 1815’s patented tourbillon stop-seconds and zero reset mechanisms. Best of all, the watch sound effects you hear, are the actual sounds of the watch. Turn up the volume!
