Fantastic work! I shoot Micro Four Thirds as well (Olympus E-P3). I am a huge fan of these little cameras.
I see from your exif that you are running up against the limitations of minimum focus distance on the kit zoom though. This is an issue for watch photos with these cameras. If you don't want to do so much cropping, you need some sort of macro setup. Fortunately these cameras are adaptable to all kinds of cheap lenses.
Here's a (handheld!) uncropped movement shot of my FF rep done with E-P3 and a $50 Chinese CCTV lens with macro rings.

All of those watches are awesome. I need a glit dial/hands sub.
