Roger Dubuis RD104SQ

Caliber RD104SQ is an automatic, skeletonized movement manufactured by Roger Dubuis. It features a multi-axis tourbillon—often called a gyro-tourbillon—that rotates on multiple axes to counteract gravity in any position. The movement is Poinçon de Genève certified, confirming finishing standards, and is built in-house. It powers limited edition Excalibur models and remains in production.
