The Catena SA100 is an automatic movement manufactured by ETA SA in Switzerland. It measures 27.6mm in diameter and operates at 28800 vph (4 Hz), featuring a date complication with Novodiac shock protection. Unlike many contemporary Swiss calibers, the SA100 is not an ETA clone and offers four calendar configurations—date at 3:00 or 6:00 with black or white text. The movement remains in production and is used by brands including Catena Swiss Space, Ferragamo, and Timex Atelier.
