I am interetsed in the evolution of the 200m Seiko dive watch. Particularly what hands were used on earlier models - pencil, sword etc.? (I think I've seen earlier 200 m divers with pencil minute hands and sword hour hands.) What movement proceeded the 7S26 and when did the 7S26 replace the earlier movement? Further, what luminescence was used on earlier models and when did Lumibrite replace it? Finally does Seiko currently manufacture Lumibrite pencil and sword style hands for the 7S26 movement and how do I get them? Thank you in advance for your help.
