Sidereus Pin Buckle.

These proprietary branded pin buckles ensure your watch fastens securely onto your wrist. The pin buckle subtly picks up the repertoire of forms and surface elements inherent in the watch body ensuring a consistency of form language between both elements.

Pin buckle finishing matches the four watch body finishes: Polished, Combination Brushed and Polished, Ion-Plated Grey or Ion-Plated Black.
