Photographing the time setting of the watch: mostly set the hands to a position that appears to achieve a sense of balance. The best results are achieved when there are three hands: the hour hand at 10 o'clock, the minute hand at 8 to 10 minutes, and the second hand at 35 to 42 seconds. Because (1) the hands are spread out, it is easy to identify the number of hands; (2) the hands are basically pointing upward, which is aesthetically pleasing (if two hands are facing downward, the dial will look like a crying face); and (3) the hands are positioned just on either side of the watchmaker's logo, which makes it easy to see the watch logo. However, watch dials with more functional displays, such as a clock, sometimes have the hands set to the 8:20 position for filming. Many functions are displayed on the dial, so be careful not to let the hands block the logo or the functions and features unique to the watch.
Regarding digital watches, it is impossible to stop the clock while shooting, so the images need to be composited in post-processing.
