These crowns use the standard tap 9 thread, so they suit watches fitted with a tap 9 crown of matching diameter, tube diameter and depth. The double O-ring design seals both inside the tube and around the stem, giving the waterproof performance needed for diver's watches. Measurements are given as crown diameter x tube diameter x crown depth, so match all three against your original crown before ordering.
⚠️ Please check the crown diameter, tube diameter and depth against your watch's original crown, as tap 9 crowns are supplied across a range of sizes and an incorrect match will not seal or fit correctly.
