It's very dark, and I see concventric circles in the blue background, usually indicative of the image having been "pushed hard" in the proicessing stage, which usually indicated incorrect original lighting and or exposure decisions. Overall, I think the watch was under-lighted or under-exposed, and the background needs to be a smoother blue.
The dark upper left and right corners look overly vignetted, too dark.
Still, not bad for your first try. You can take this shot and move onto better watch shots with a few subtle tweaks to this existing set-up!
