SEIKO 70's / 45 KING SEIKO SUPERIOR CHRONOMETER / Cal.4502A

Introducing the Seiko " 45 King Seiko Superior Chronometer" made in 1970 .

The Cal. 4502A used in King Seiko is a movement that was refurbished for commercial use from a mechanism developed by Daini Seikosha Kameido Factory for chronometer competitions.

Commonly known as the " 45 series machine," it was created as a rival to Suwa Seikosha, which was developing Grand Seiko at the time.

Their skills were well-known, and they came in second place among strong manufacturers at the 1967 Neuchâtel Chronometer Competition in Switzerland.
The following year, in 1968 , it officially passed the Japan Chronometer Association Certification for the first time.

Furthermore, it meets Seiko's unique " GS standard" and was later installed in Grand Seiko, making it a masterpiece movement that cannot be left out when talking about Seiko history.

■Dial and case design

The Seiko " 45 King Seiko Chronometer Superior" we are introducing this time is a model that features the words " CHRONOMETER " and " SUPERIOR " at the 12 o'clock position on the dial.
The Superior designation is known to be a rare specification, with a limited number of units produced.

The dial is a silver dial with a sunray finish that reflects light radially.
The upright bar indexes are matched with bar hands, both of which have black centers.
In addition to being highly visible, the details give the car a more refined look.
The clean design makes the markings at the 12 o'clock position stand out.

The case has an attractive, sharp surface structure that is characteristic of the 45 King Seiko.
The line runs seamlessly from the bezel to the lugs, and the thin, wide outline gives the wrist a clean look.

When viewed from the side, the case's slim profile stands out, and it fits easily under a shirt sleeve.
With its mirror-like shine and sharp edges, the case design exudes a refined look befitting the name "Superior."

Please be sure to read the following information after purchasing an antique watch.

When selling antique watches at RESUME, we do not immediately hand over the watch to you upon receiving your order. Instead, we have a professional overhaul (hereinafter referred to as OH) the watch, and then we deliver it to you after the OH is completed. (This takes about 1-2 months.)

When we deliver the machine to you, we will also send you our own overhaul certificate, which will show you what kind of overhaul work was done on the machine, as well as photos of the machine being disassembled and serviced.
