The GMWB5000PC-1 is the full-metal iteration of the DW-5000 base model, representing a refinement of its hollow case structure for enhanced shock resistance. This design incorporates fine resin shock absorbers between the metal bezel and case, creating a robust shock-resistant system for an all-metal construction. The watch features an innovative band connection system with additional center lugs to reduce stress on the band pins, addressing areas subjected to the highest impact. The screw back case is treated with a diamond-like carbon (DLC) coating for wear resistance, and a film solar cell provides power.
