Astron GPS Solar Watch SSJ025J1

The Watch

Seiko offers an extensive range of timepieces - from robust dive watches to refined, sophisticated creations - catering to every watch enthusiast's taste. As diverse in aesthetics as in technology, the brand's iconic collections - including the Seiko 5, Prospex, and Grand Seiko - showcase its remarkable versatility. Every model strikes the perfect balance between design, functionality, and ergonomics, built from quality materials for lasting durability and shock resistance, without ever compromising on style. In the Astron collection, you'll find this exceptional SSJ025J1 watch - ready for any occasion. It features a round case with a silver tone, crafted from scratch-resistant brushed titanium for superior resilience. With a 42 mm diameter, 48.60 mm length, and 12 mm thickness, it is perfectly proportioned for men's wrists. The case is topped by a sapphire crystal with a super-clear coating, protecting the dial from scratches and external shocks. The grooved crown and two pushers at 2, 3, and 4 o'clock provide access to the hours, minutes, date, and additional functions. Finally, the screwed case back ensures water resistance of 10 ATM.

The Dial

This stunning dial in black features a double circle finish for added depth and character. Its sandblasted center evokes a star-filled sky, while the matte outer ring is marked by a minute track flanked by the letters Y and N, indicating whether GPS signal reception is complete or has failed. At the center, three hands display hours, minutes, and seconds - all treated, along with the indices, with LumiBrite coating for excellent legibility in low-light conditions. A date window sits at 3 o'clock, and a sub-dial at 8 o'clock shows the reception process, airplane mode, charge level, and leap second data reception status. Seiko's name is inscribed near 12 o'clock as a signature.

The Movement

This timepiece is powered by a Japanese-made GPS solar movement - specifically the Seiko 3X62 caliber, which drives the hands, date window, and sub-dial. It features 10 jewels and oscillates at a frequency of 32,768 vibrations per hour. The movement delivers a power reserve of approximately 6 months at full charge and approximately 2 years in energy-saving mode, with an accuracy of ±15 seconds per month (without GPS signal reception, at temperatures between 5 and 35 °C).

The Strap

A silver-toned bracelet is paired with this men's watch. It is crafted from brushed titanium with a scratch-resistant coating for enhanced durability. The lug width is 14 mm, and it fastens easily with a single deployant clasp with push buttons.

Water Resistance

This model offers water resistance of 10 atmospheres, or 100 meters - a truly water-resistant watch. Ready to dive into aquatic adventures with you, it handles everything from puddles to the pool without complaint. Showering, bathing, and recreational swimming are all no problem. That said, watchmaking experts note that while this model is water-resistant, it is not designed for diving (professional or otherwise) and should be kept away from high-pressure cleaning equipment. We also recommend not operating the crown or pushers while submerged.
