Seiko SQ 4004 from April 1977
-New Battery
-NOS Hardlex OEM Crystal
-Runs and Keeps Time
-Quickset Functions Flawlessly For Seiko, the 70s were all about getting their new quartz technology into the market. Some say this is the golden era of quartz as they were large, robust, and the most accurate watches available at the time. Their SQ line was launched in order to make well finished quartz watches available to more people.
The 4633 cal is a serviceable movement launched in the mid 70s. This watch has the heft and size one would expect from an automatic but with the low maintenance of a quartz.
This watch works excellently. Please reach out if you have any questions.
