Built around a 40mm stainless steel case and a fine Milanese mesh bracelet, the Calvin Klein Iconic Automatic brings a mechanical sensibility to the brand's characteristic minimalism — its grey skeleton dial exposes the motion of the movement through an open-heart aperture, while an exhibition case back invites a closer look at the self-winding mechanism within. Powered by an automatic movement that winds from the motion of the wrist, there are no batteries to contend with — just a date window, baton indices, and the quiet confidence of a watch that lets its engineering do the talking. Water resistance to 3 ATM keeps it honest for daily wear, and the sliding mesh clasp ensures a clean, tailored fit across the wrist.
