If you're doing a Seiko watch repair or just want to keep the dust out, this is the rubber case back gasket you need.

It fits a bunch of Seiko movements and case backs, including the H023-00C0, 7L22-0AE0, H023-00E, and 7D48-0AA0.

It's made in the United Kingdom, so it's good quality.

It's a new old stock type part, with tags.

If your old gasket is flattened or cracked, replace it to keep your watch sealed up tight.
