Nice watch from TagHeuer

Reinventing the mechanics of timekeeping, TAG Heuer has created a movement that owes more to high-performance racing car engines than to the pinions, coils and springs of a traditional automatic watch. The 'V4' (pictured) keeps the beat through a beautifully automotive system of barrels and belt drives. Best of all, having gone to such trouble over its new movement, TAG left it visible behind a confidently chunky face of bevelled sapphire crystal.
