All about the Seiko SKA791P1: a Kinetic watch with a green dial

The Seiko Kinetic collection: precision and ecology

The Seiko Kinetic collection embodies Seiko's innovation and commitment to sustainable solutions. Since its launch in 1988, Kinetic technology has revolutionized watchmaking by combining the precision of quartz with the autonomy of mechanical movements. Each movement of the wrist generates energy, which is stored in a battery, offering an environmentally friendly alternative to traditional batteries.

Among the flagship models in this collection are the SKA791P1 , but also the Seiko SKA783P1 with its deep blue dial and steel bracelet, or the Seiko SKA785P1 with a black dial. The Kinetic range offers watches suitable for both sports enthusiasts and those who love elegant watches.

A refined and versatile design

The Seiko SKA791P1 features a stainless steel case measuring 42.6 mm in diameter and 11 mm thick .

Its deep green dial with Lumibrite gold indexes and hands ensures excellent readability. The Hardlex glass , exclusive to Seiko, protects the dial from scratches and shocks.

The brown leather strap , 22 mm wide, offers a comfortable fit and an elegant touch, with a pin buckle. The case back is transparent, allowing you to observe the Kinetic mechanism of caliber 5M82.

What is Seiko's Kinetic Movement?

The Kinetic movement is a watchmaking technology developed by Seiko in 1988. It is a hybrid system combining the precision of quartz with the autonomy of automatic watches , without requiring a conventional battery.

It works thanks to a rotor that turns with each movement of the wrist. This rotation generates kinetic energy transformed into electricity by a miniature generator , then stored in a rechargeable accumulator (formerly "capacitor").

Benefits of Kinetic Movement

No batteries to change regularly : energy is generated naturally.
Autonomy : up to 6 months of power reserve after full charge.
Accuracy : ±15 seconds per month.
Eco-friendly : less waste from disposable batteries.
Reliable and proven : over 30 years of technical improvements.

Special features of Kinetic calibers

Power reserve indicator : via a push button at 2 o'clock.
Low charge signal : hands in 2-second jumps.
Long-lasting capacity : up to several years of autonomy (Kinetic Perpetual).
