Our professional watchmakers have fully overhauled and polished this timekeeper in July 2026, ensuring optimal aesthetic and operational performance for years to come.

2. Case Metallurgy, "Griffes", and Dial Finish

The case architecture utilizes premium surgical-grade stainless steel combined with 18K Yellow Gold accents. The most prominent engineering feature is the "griffes" or claws at 3 and 9 o'clock, originally designed in 1982 to hold the sapphire crystal firmly against the gasket for superior water resistance. The pristine white dial offers high contrast and perfect legibility.
