Standard height domed profile, suitable for most watches within the 30mm-40mm range where the case takes a friction-fit acrylic crystal. To choose the right size, measure the gap in your watch case and select a crystal approximately 0.2mm larger than that measurement — it will compress slightly as it pushes in, giving a snug, secure fit.

⚠️ Please check your case gap carefully before ordering — buying the correct 0.2mm-oversized size is essential for a proper friction fit, as an undersized or oversized crystal will not seat correctly.
