Alpina AL-490

Alpina's ultra-thin hand-winding caliber with small seconds. Based on the slim ETA 7001 architecture, enabling dress watch proportions. The 2.5mm height makes this one of the thinnest movements in the Alpina lineup. Features a small seconds subdial at 6 o'clock. Operates at a traditional 21,600 vph (3Hz) frequency. Used primarily in Heritage and dress watch collections where slim profiles are essential.
