Probably because you got the camera so close to the watch. That distorts the image and makes everything in the center look disproportionately huge. A photo from ~12 inches (~30cm) away would make it look more natural.

There are multiple sizes tho. The hand wound is only 34mm, while the automatic and quartz versions are 38mm. That’s also probably why you can get the 34mm for ~500$ easily, while the other ones are more expensive.
