✅ Fits

Diameter is the deciding measurement, not brand — this is a universal replacement for any round case that takes a glue-in or gasket press-fit crystal of the correct size. It's a common trade replacement for the Orient Bambino and Seiko SNK801, SNK803 and SNK805, and can also fit other Seiko, Orient, Citizen, Bulova, Omega, Tissot and Hamilton watches where the diameter lines up.

⚠️ Please check your exact crystal diameter (measure the old crystal or case aperture with a calliper) before ordering, as fit is determined entirely by size rather than watch brand.
