One trick for taking pictures of watches is to place them flat on a table and then put your smartphone on the lip of a coffee cup next to them.
It takes a completely crystal clear detailed picture of the watch's dial.
This is the advice I got from a user on here named @Syrte and I've used that camera technique ever since.
By the way, your wrist shot in the first picture is really good, but the third pic of the two watches is blurry.
