Bell & Ross BR-CAL.306

The BR-CAL.306 is an automatic movement manufactured by Bell & Ross and used in the brand's instrument-style watches. As part of the BR-CAL family, it is not in-house, instead relying on a modified base caliber to provide timekeeping with additional complications. The movement remains in production and appears in several of Bell & Ross's iconic diving and aviation-inspired collections. This approach allows the brand to offer functional complications while maintaining accessibility within its distinctive square-case design language.
