Brand new reproduction mineral glass replacement. Made out of Hardlex, the original material Seiko used. This is the correct crystal used for first-generation 7002 dive watches made between 1988 until the mid 1990s until the introduction of the 7002-7039 200m “Transitional”. It has been unavailable from Seiko for more than 20 years.
