The Opera Godfather stands as the most famous musical complication watch from Jacob & Co. A built-in mini music box plays the iconic Godfather theme via a violin-shaped winding crank, combining skeletonized movement layout with premium precious stone setting. Unlike generic minute repeaters, Jacob & Co custom tunes each musical module, turning the watch into both a timing instrument and an auditory collectible. BRM Chronographes leans into motorsport rugged chronograph design, while Jacob & Co leans into artistic, theatrical mechanical entertainment for high-net-worth collectors. <p>richard mille RM UP-01 Ferrari </p>
