Hi @matrix! I just replied in my thread, and now see you have your own WIP one. As I said there - mine is nothing special. It's actually a free model available on Model+Model. It's just a plane with the clock background which I gave some self illumination, and a glass geometry with basic thin glass material as there was no need for any refraction.
I think a big part of it will be getting a nice studio lighting set up to give some highlights to make your model "pop" as they say. Or if you want it in a more regular scene you could take a look at
Maxime Roz. He has some really nice interior HDRIs, both free and another very reasonably priced pack there. The quality of them is excellent, and you'll get some really nice lighting for your scene.
