Seiko 7C46 NOS Quartz Movement For Tuna 300m 600m 1000m - With Stem And Spring

Attention, Seiko modders and repair enthusiasts!

Here's a gem: a brand new old stock (new with tags) original Seiko 7C46 quartz movement.

This is the heart of the legendary Tuna monsters—the 300m, 600m, and 1000m divers.

Made in Japan, this movement is ready to breathe new life into your favorite build or repair.

It comes complete with the stem and spring, saving you the hassle of tracking down those tiny parts.

It's a modern movement from 2010 or later, so it's fresh and ready to tick for years.

If you're building a frankenwatch or just need a reliable replacement, this is it.
