Sapphire Box Crystal to replace OEM Hardlex on Seiko Cocktail Series Watches #Cocktail-BX

This is an after-market box sapphire crystal that you can use to mod and upgrade your Seiko Cocktail series watch. The crystal is the same size as the factory installed crystal. It has no AR to maximize optical clarity. It can be installed on Seiko SRPB41, SRPB43, SRPB46, SRPB77, SSA358, SSA359, SRPD36, SSA343, SRPD37, SSA393, SSA392 watches.

Note: This is a box crystal, which is more complex to manufacture than a domed crystal. The ‘box’ crystal gets its name from the sharp rise of the crystal at its outer edges. The crystal is held in place with adhesive, it is not a press fit. Professional installation is recommended.
