The BERGEON 5538 is a professional Swiss-made case opening die set designed for use with the BERGEON 5700-Z and 5700-A Waterproof Watch Case Opener. The set is specifically engineered for opening and closing grooved Oyster-style screw-down case backs, commonly found on Rolex®, Tudor®, and other watches utilizing similar fluted case back designs. 

The set includes six precision-machined opening dies and an intermediate adapter holder, allowing the dies to be mounted securely onto the BERGEON 5700 series opener. These dies are manufactured to exact tolerances to provide a secure fit on grooved case backs while minimizing the risk of slipping and scratching during servicing.
