This is the Tuner hardware on my Classical Acoustic guitar.
Shot this using my 15-55mm XTI kit lens using a hand held reverse macro technique. (No fancy lens or mounting ring here) I lit the tuning head with a white and a blue L.E.D. flash light. Then I took the photo into light room for a quick saturation and color balance.

Nice. This looks like a mechanical tuner for a guitar to me. Fun composition, I might have tried rotating just slightly counter clockwise as the slant of the left spiral part gives a slight 'tilted horizon' feel. I like the colors, it looks like perhaps you used a bluish lighting? Anyhow, I like the blue complimenting the gold of the sprocket. Nice Job (I'm doing scoring after commenting/guessing).
Be careful with using on body shutter release when doing Macro shots even on a tripod as the tiniest vibration or movement cause a huge jump in the frame and blurs the focus.
