is the very first watch collection ever released by Alpha Sierra. This chronograph men’s watch marked the beginning of the brand and laid the foundation for its design language and identity.

The Intruder Series is defined by its bold case design, distinctive chronograph layout and strong visual presence. From the very start, the focus was on creating a watch that felt confident, technical and unmistakably Alpha Sierra.

As the origin of the brand, Intruder holds a special place within the collection. It represents the moment Alpha Sierra took its first step, combining functional chronograph design with a clear and powerful aesthetic. Intruder is more than a watch; it is where the story began.
