This model revives the front-button design of the 52QS, originally released in the late 1970s, featuring a full metal case. The case is meticulously polished with hairline and mirror finishes, complemented by iconic metal front buttons. Subtle function indicators enhance the premium feel, while the flat, multi-row band balances retro aesthetics with comfortable wear.
