Vintage 1967 Seiko Sportsmatic 820 - Work Progress
1967 Seiko Sportsmatic Calendar 820. Before and After. Using hand and Dremel, I took Polywatch to the Hardlex crystal and Brasso to the case. It's good for now and will be a good everyday carry. However when time permits for full servicing, then I'll replace the crystal, which I have.

By the way strictly speaking that removed the word calendar from the dial at that point. Everything before this year had calendar 820.
That is a beautiful watch, I love the old Seikos. I didn't know Polywatch would do anything with hardlex good to know.
