These rubber O-ring gaskets sit between the watch crown and the case tube, forming the waterproof seal that keeps moisture out around the crown stem. The set covers 12 different sizes so you can match a gasket to the crown you're repairing, with each size kept separate in its own labelled compartment for quick, mess-free selection.

⚠️ Please check the size chart/photo against your crown tube before fitting, as crown gaskets vary in diameter and thickness between watch models — fitting the wrong size can compromise the water seal.
