Thank's Maxashi
for the lighting i did my self with my own lighting studio setup, it's manually without HDRI, i used the real reflection from the object, see my attachment
in this scene i used 3 kind of lights,1.Photometric light/spotlight as main light,which is create the strong shadow, 2. corona lights (sphere) to create highlight and 3. corona lights (box) as softbox in photography, then for the reflection effect i added 3 plane object with coronalightMtrl and i put gradient ramp in the diffuse color, also one big sphere to create dramatically reflect in the watch.
i hope it's clear enough for you, thank you
