A good design, but two things are missing. One from the model, the other from the image. First, I don't see a crystal. It might be there but so completely transparent that nothing reflects, and I'd expect to see it with the light at that angle. Second, and this is only an idea that I don't even know if it's possible in your software, is to add some depth of field to make it really look like you took a photo of your watch.
