Product description

This beautiful, limited to 1500 edition Seiko Astron. Is inspired by the night sky, with countless stars and galaxies which converge at the centre, from which the hands revolve their faithful rounds. The dial surface is a newly developed, embossed spiral structure which simulates the energy of moving stars. To preserve the jet-black sheen, the case and bracelet are finished with a special scratch-resistant coating. The clasp adjustment system ensures precision sizing. A perfect blend of technology and innovative use of materials and design, this Astron watch is a must-have for the true watch enthusiast.

This Seiko watch has a case made of Titanium with a diameter of 43.4 mm and is fitted with a Titanium strap. Inside the case lies a Seiko movement and the watch features a Double anti-reflective sapphire crystal.

The watch is 10ATM. This means the watch is suitable for swimming. The watch comes with 3 Year Warranty.
