Nice...
I think you have to compare the watch with something else ... I didn't like the golf ball..

Ok, time is an abstraction, it's not an object, I've overdimensioned time with a watch of 14 hours, then I thought that maybe moderators could reject my entry so I've rendered it with a golf ball in "real" size (I've placed it on an evironment)

without a golfer, the golf ball has no value... and it doesn't show the contrast enough

suggest
1) add golfer
2) surrounding grey, change to grass on a golf-course

Nice image and the idea is very creative. But the camera angle lets it down. Maybe more of a 45 degree angle with the watch laying on a table top with the golf ball beside the watch instead of on it would have given you a more believable and pleasing size comparison
