Seiko Astron GPS Solar Dual Time Chronograph Limited Edition 43.4MM - HAB005J

Reference Number:  HAB005J

Limited Edition. 1,200 pieces worldwide. Special box and additional silicone strap. Serial number selection is not possible as watches are sent at random worldwide.

An update to an iconic model, the Seiko Astron HAB005J brings with it a sharper look, a more robust movement and outstanding levels of accuracy and reliability signalling Seiko's continual elevation of the Astron as one of the most practical and technically impressive travel chronographs on the market.

This model features a sharper, modern profile and a bolder wrist presence catering to those who enjoy a sportier look. Its integrated titanium bracelet and the additional silicone strap allows for several looks and a lightweight durability suitable for daily wear. It should be noted that this watch features a quick change system, removing the need for additional tools to change straps.

Perhaps most striking is the watch's vivid green pressed pattern dial, inspired by the facets of a quartz crystal. This gives the dial a dynamic character, catching the light differently depending on the angle. 

These updated aesthetics do not come at the cost of function. The dial retains its practical, dual time chronograph display whilst the watch is powered by the updated Calibre 5X63 movement, a new-generation GPS Solar Dual-Time Chronograph movement that sits at the heart of the watch’s technical identity. This allows the watch to remain accurate to within ±1 second every 100,000 years when daily automatic time adjustment is active. The Seiko Astron HAB005J represents not a reinvention but rather an evolution of the Astron line, a bold watch with character, perfect for the traveller or for an individual who wants a truly unique timepiece
