I like a lot of it, specifically the 3d depth effects (flare, 3d text, shadow).
I would suggest possibly moving the flare a bit further from the second hand though as it becomes fairly noticable. Instead of being a passive effect, my eye keeps bouncing between the second hand and the flare if that makes sense.
Also, I'm not sure but the gear in the bottom left seems off.. look at the bottom of the casing that houses the gear. The gap changes in size.
Finally, I'd try adding a gradient to the background since everything else has some depth tricks applied to it. While you don't want to suggest depth, it being solid feels off to me.
Either way, again nice work, these are just my personal thoughts feel free to ignore
