This 2025 limited edition of 60 pieces features a 37mm stainless steel case with the iconic angular design and fourteen-sided bezel of the 1969 Defy. The Golden Yellow dial is accented by grooved square markers and silver azuré counters, drawing inspiration from USM Haller furniture. It is powered by the El Primero 400 automatic column-wheel chronograph movement, offering a 55-hour power reserve and 100-meter water resistance. The exhibition case back reveals an openworked rotor adorned with Zenith and USM logos.
