Seiko just unveiled the Astron GPS Solar 2024 Limited Editions SSH157J1 and SSJ027J1. Both feature a transparent, patterned dial inspired by the starry night sky and a multi-faceted angular titanium case with contrasting satin and mirror-polished surfaces. Though styled like conventional watches, they are high-tech and run on Seiko’s proprietary GPS solar movement, which is accurate to +/- 15 seconds per month and has six months of power reserve.

Initial thoughts

Well liked for its value-minded offerings, Seiko does well with watches like the new Astron GPS. They are practical, high-quality watches that have some of the stylistic glamour of pricier timepieces thanks to the facetted case and integrated bracelet.

Featuring a reasonable prices of US$2,200 and US$2,500 respectively, the new Astron pair offers are amongst the more expensive electronic watches but executed as well as mechanical offerings in the same price segment.

The titanium are finished well and the moulded sky-blue dials with applied indices are unusual elaborate for electric watches. Putting the high-tech movement aside, the quality of the dial and case are good for the price range.

Bang for your buck

The Astron GPS Solar models offer a chronograph function and run on a GPS solar movement with a power reserve of about 6 months. They are each equipped with different movements, with the SSH157J1 offering additional functionalities like the world time and the day display.

Although both feature an angular titanium case, the SSH157J1 is equipped with a ceramic bezel, while the relatively affordable SSJ027J1 sports a matching titanium bezel. Both are fitted to an integrated bracelet and boast a transparent light blue moulded dial inspired by the starry night sky.

Both models feature applied indices and sword-shaped hands. They also sport a similar-style closed case back with the limited edition number printed on the reverse side.
