✅ Fits
Fit is determined entirely by diameter, not brand — measure your original crystal or the inner bezel opening and select the matching size. This makes it suitable for a wide range of watches, including:
-
Seiko — including SNK801, SNK803, SNK805, SNK809, and other models sharing the same crystal diameter
-
Orient — including Bambino
-
Citizen, Bulova, Omega, Tissot, Hamilton, Fossil — wherever the original crystal diameter matches the size selected
-
Panerai non-date models — this flat-base domed profile is a recognised fit for this family; match to your reference's diameter
-
Accurist Skymaster models — a confirmed fit for this crystal type
Can be installed by gluing into the case or press-fitting into a crystal gasket (I-gasket); the flat base seats evenly while the domed top gives a period-correct look.
⚠️ Please check diameter carefully — sizes go up in 0.5mm steps only, so measure the inner diameter of the crystal seat at the base of the bezel (not the outside of the case). The 2.5mm edge is taller than many original crystals; this is normal for a service replacement and won't affect fitment in most cases.
