Introducing: Zenith Defy Revival A3643

For LVMH Watch Week 2026, Zenith continues its Defy Revival series with the reintroduction of the Defy Revival A3643. The model is a faithful reinterpretation of a Defy reference originally introduced in 1969, the same year Zenith launched the El Primero calibre. Following the Defy Revival A3642, released in 2022, and the A3691, released in 2023, the A3643 returns to one of the earliest Defy executions, distinguished by its silver-toned dial.
