Live Pictures

Why do we also use Live Pictures? Even if it looks less professional on a official website, you can only see the quality of the watches from such photos. All watches look great on official product images. Even the cheap ones. But in order to get an accurate feeling of the watches, you have to hold them in your hand. These often have a completely different effect. However, since our customers mostly order online and cannot view the watches beforehand, our pictures must be as authentic as possible.


The "Aventurine" is certainly one of the most beautiful dial variants ever. The tiny dots on the gem sparkle like millions of stars, making the dial look like a starry sky. Unfortunately, this effect cannot be captured in pictures. That is why we strongly recommend watching the videos in the links below so that you can better understand what makes these watches special. The videos shows the larger 43 mm model. Please just click on the text:
