【KING SEIKO】Ref.5626-5010

A rare square face King Seiko 5626-5010 manufactured by Suwa Seikosha in September 1971 is now in stock.

This watch with cut glass is a King Seiko with a strong design and presence.

The case has some minor scratches, but nothing major that would stand out, and the dial is in good condition. The glass has been replaced with genuine NOS glass.
It comes with a genuine King Seiko bracelet.
The day of the week is written in Japanese and English in Japan. The back cover is made like a box and is designed to protect the movement from shocks and water more than usual.

The movement is equipped with a high-beat automatic "Cal. 5626A" movement. This Series 56 movement was the first Japanese-made automatic movement to be chronometer-certified and oscillates at 8 vibrations (28800 rpm), and was developed to enhance accuracy.

It has a hack function and date quick-change function, and the weak part of the date quick-change function has been replaced with a metal one.
