Firstly, what message does your product like to convey? In this retrospect, you must consider a certain number of factors, like target audience, their tastes, population demographics, etc.
Then, THE advertising shot ALSO depends on the type of marketing campaign it is presented in. For example: the BMW "Mini" campaign. Notice that the car is marketed as part of an ideal 'trend setter's lifestyle", thus the advertising shots on the Mini has to fulfill this criteria, depicting a 'trendsetter'''s mundane day and how she has to finish her day with the Mini. An advertising shot must contain the marketing message.
Usually, an advertising shot has to make use of clever lighting/shallow DoF to emphasize the product or subject. In other words, the photograph must make the product stand out. You have definitely fulfilled this criteria, BUT the image must fulfill the above conditions as well. Otherwise, it is just a shot of a watch.
