Oval silver pocket watch with silvered dial, moon phase and regulator-style hands, held in a hand

I was once allowed to hold this unique oval tourbillon, made by Derek Pratt for Urban Jürgensen, and to study it in all its details. It is a moment I will not forget.

The dial side has a moon phase and a regulator-style layout; the reverse shows the gilt movement with the tourbillon.
