320W10GN00 Type II
Brand new reproduction mineral glass replacement. Made out of Hardlex, the original material Seiko used. This is the correct crystal used for 6105-811x dive watches made between mid-1970 to late 1975. It is by far the most commonly used crystal watches and has been unavailable for more than 30 years. We are the only source for this reproduction 320W10GN00 Type II crystal.
This lower version was created by Seiko to replace the earlier Type I, which has a higher profile. The higher profile often had edge chipping. Seiko replaced the Type I with a Type II to alleviate this.
