Analog watches on Amazon are usually set to 10:08 (or at least, they appear to be set to that position) for a few different reasons.
First, this position is easily recognizable, so customers can identify it quickly as an analog watch. By making the hands on the watch face point to 10 and 8, it stands out - creating a visual cue that anyone can recognize.
Second, the 10:08 position represents a time of optimism and success. Placing the watch hands to this position on a watch sold online actually serves a purpose - it encourages potential buyers to think about the potential of owning a watch and all the positive opportunities that come with it.
Third, 10:08 has more technical significance. It is used to calibrate watches, meaning it is easier for manufacturers and watchmakers to set up the positioning of the hands of the watch face at an even and symmetrical angle. This improves the accuracy of the device and also makes it more aesthetically pleasing.
Finally, 10:08 is a relatively common practice in the watch industry. This makes it easier for Amazon (or any other watch supplier) to produce similar watches with fewer complications.
Overall, the 10:08 positioning is used on watches sold on Amazon for a combination of aesthetic, psychological, and practical reasons.
