Case and Crystal Excellence
The case measures 44mm in diameter with a thickness of 15mm, striking a balanced profile that sits comfortably on the wrist. Its curved bezel is polished to a high sheen, reflecting AZ's unwavering commitment to quality.

Through extensive disassembly and data analysis, AZ has achieved an 80% structural match with the authentic movement, while the winding and setting mechanisms are 100% synchronized in feel and operation. This ensures a reliable and satisfying user experience.
