The Seiko Astron The Green Nebula Chronograph Watch (SSH079J1) is a captivating timepiece inspired by the mesmerizing beauty of astronomical nebulae, reflected in its gradation of colors and glittering dial. This watch not only offers a visually striking design but also ensures excellent night-time visibility with entirely LumiBrite indices, providing a functional and stylish accessory.


Powering the watch is Seiko's groundbreaking GPS solar technology, making it the world's first GPS solar watch that eliminates the need for battery changes. The SSH079J1 guarantees precise timekeeping with automatic time zone adjustments through GPS signals, ensuring accuracy across different locations and time zones.


Key features include the Calibre Number 5X53, delivering remarkable accuracy with ±15 seconds per month precision, even in the absence of GPS signals, and operating effectively within specific temperature ranges. The watch boasts a power reserve of approximately 6 months when fully charged, extendable to about 2 years with the power save function, providing practical functionality for daily use.


Constructed with a stainless steel case featuring super hard coating and a ceramic bezel, the watch not only offers durability but also exudes a sophisticated aesthetic. The dual-curved sapphire crystal with super-clear coating ensures optimal clarity, and LumiBrite on hands and indices enhances visibility in low-light conditions. With a case diameter of 42.7mm and water resistance up to 100m, the SSH079J1 strikes a balance between a robust build and a refined design.
