It’s an original new old stock Seiko 7C46 quartz movement, the heart of the legendary Tuna divers (300m, 600m, 1000m models).

Made in Japan, this is a genuine Seiko movement, never used, with tags.

It comes with the stem and spring included, so you’ve got everything to build or repair your Tuna.

Year of manufacture is 2010-now, so it’s relatively fresh.

Whether you’re restoring a classic or building a custom diver, this 7C46 is the real deal.
No UPC, just pure Seiko quality.
