VH31 movement, what are the specifics of this seiko movement?

For our watch Concordia Quartz, our adventurer's watch, we chose to equip it with the movement VH31 Sweep second Seiko's.

Seiko, a Japanese manufacturer with big ambitions

The history of the Seiko factory began in 1881 when Kintaro Hattaori opened a watch sales and repair shop in Tokyo.

A little more than 10 years after Kintaro Hattori started clock production under the name seikosha after the purchase of a disused factory. Firmly determined to compete with Swiss watch houses, Seiko launched his first pocket watch in 1885, and a few years later opened the way to wristwatches. The first seiko bracelet watch, the "Laurel" was founded in 1914.

During the 20th century, Seiko developed many technologies, with the constant aim of improving the performance of their watches, like their shock-proof system, or mechanical watches with automatic winding.

But it was in 1969 that Seiko changed the world of watchmaking (forever), through the very first watch in Quartz, the seiko Quartz Astron, a watch much more precise than mechanical watches running with a battery.
