Reference only — not currently in stock

The Zenith Defy Chronograph USM 03.A780.400-1/65.M3642 debuted in 2025 as a limited edition of 60 pieces. Its 37mm stainless steel case features the angular form and fourteen-sided bezel introduced on the original 1969 Defy, here paired with a ladder bracelet in the same material. The Golden Yellow dial is highlighted by square markers with horizontal grooves and three silver counters with circular azuré finishing, reinforcing the architectural inspiration drawn from USM Haller modular furniture. At its core is the El Primero 400 automatic caliber, a column-wheel chronograph running at 36,000 vph with a 55-hour power reserve. Displays include hours, minutes, small seconds, chronograph seconds, a 30-minute register, a 12-hour register, and a date at 4:30. The sapphire case back showcases the openworked rotor with Zenith and USM markings. Water resistance is 100 meters.
