Vacheron Constantin Overseas Tourbillon 6000V/110A-B544

Overseas Tourbillon references place the open cage at the center of attention, making its alignment, visible motion, bezel seating, and case-to-strap fit critical review points. Brushed, polished, plated, gem-set, leather, rubber, and bracelet surfaces can show small production variation, which should be judged from the actual QC set. Crown resistance, rotor sound, bracelet articulation, strap stiffness, clasp tension, and setting feel may differ slightly 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.
