Looks like a good box d4me! Very nice photos too.
All best watch photographs have been Photoshopped. If a "hotshot" photographer claims that his pictures are "untouched", he's lying to his teeth. However, there isn't a lot to do when you get the lighting correct. Usually I take off small dust spots off and alter the contrast/brightness levels. Though I have done some heavy PS work too... but those are more PS compositions than actual photos.
Some watches are more challenging to shoot than others. Taking decent photos is easy, but when you want to go to the next level you need more work and practice. Usually "decent" photos have noise and lacking details, like the bracelet brushed areas and such. Getting technically decent photo is easy, but a great photo is much more difficult. It's all about the light exposure.
More light is always better than less. There is a fine line between correct light exposure and exposure that goes overboard. Finding that balance is difficult. And yeah, I usually take about 10 pictures of the same setup, and I get roughty 1 acceptable one. When I started, the ratio was 100/1.
And yeah, camera doesn't mean much. It's the lighting, lighting and once again lighting. Expensive camera won't make your photos any better, if you don't accept this fact. Then you need to have "eye" for the post-processing with PS. That's it.
It's very enjoyable to get a good watch photograph. I highly recommend getting into it, it's fun.
