Hi Jeff - good choice in camera. What lens are you using for the watches?
I think your lighting set-up is excellent which is evident from the pictures i.e. even illumination on the dial and no reflection off the glass. If you have Photoshop (Elements of CS...) I would suggest that you have a play with the levels. This is usually represented as a curve on a graph with dark, mid tone and light sliders. If you bring the dark and light slider inwards to the point of the curve where it just starts to rise you will get a better contrast and colour rendition. If you shot the image in RAW format you will need to sharpen.
There are lot of settings on the camera and fully automatic is one. To avoid disappointment and the potential wrath from the wife and family for messing up the pictures go for auto setting. That’s if you have not already read the 400-page user guide at least twice.
Regards
Paul
