Rolex Tourbillon All Black Automatic movement

The open tourbillon display is the main visual focus, so cage alignment, visible motion, hand clearance, and case finishing should be reviewed closely. Modified ceramic, carbon, plated, gem-set, rubber, leather, and bracelet components can show small production variation, which should be judged from the actual QC set. Rotor sound, crown resistance, bracelet articulation, strap stiffness, clasp tension, and setting feel may vary between individual watches. Any stated water-resistance figure is a factory rating, not a promise for swimming or immersion; independent pressure testing is recommended before water exposure.
