Authentication guide

Last reviewed June 2026

The Felix is Habring²'s three-hand automatic with a small seconds sub-dial, not a flyback chronograph despite the family context. The Cal. A11B is the standard automatic variant of the Habring architecture. At 38.5mm and 8.7mm, it is among the slimmest Habring pieces.
