Nice lighting, the color seems a little off to me though. I'm not sure why I think that because that is probably the right colors, that was just my initial reaction.
Interesting choice of display for your product. It works. The colors together don't show off the watch to its best advantage, I think... but the DOF and focus and lighting are really well done.
Technically this is really well done. Exposure and lighting are great and I'm sure what's being sold. Comp is great for eventual text placement. The only detraction is whatever the watch is on.
