Watch: Seiko Astron GPS Solar Dual-Time Chronograph
Caliber 5X63
The new Caliber 5X63 integrates Dual-Time technology with a chronograph function capable of measuring up to 24 hours in 1/20-second increments — a genuinely useful complication for travelers who want to track both home and destination time with precision.
The GPS Solar movement automatically adjusts to your location anywhere in the world by receiving satellite signals, and offers world time across 38 time zones, a perpetual calendar, and a chronograph, all powered by light with no battery to ever replace.
Design
This new creation inherits Astron's signature dynamic case design, defined by its multi-faceted, three-dimensional profile. Part of the latest Astron Nexter collection, it pairs cutting-edge GPS technology with sophisticated Japanese craftsmanship in a striking blue-gray geometric dial inspired by modern architecture.
Case
The brushed finish on the top surface of the faceted bezel contrasts elegantly with the polished sides, enhancing the piece's presence and architecture. Crafted from super-hard coated titanium, the 43.4mm case is lightweight yet exceptionally durable for daily wear.
Dial
The sub-dials align horizontally across the dial in a symmetrical arrangement. Set against the main dial's geometric pattern of interlocking triangles, the overall composition conveys a sense of balance and solidity.
Bezel
The HAB001 introduces a newly developed two-piece octagonal titanium bezel, which lowers the center of gravity and improves the wearing comfort of the lightweight titanium case.
Bracelet: The Quick-Change System
The HAB001 features a quick-change system that lets you remove the bracelet easily with the push of a button; attaching a strap is just as simple — just snap it into place for a secure fit. This lets you instantly switch between the titanium bracelet and an optional exclusive strap, adding versatility and enhanced functionality to a single watch.
Built for Precision and Everyday Durability
The 43.4mm titanium case is paired with a sapphire crystal featuring Seiko's Super-Clear coating for outstanding legibility in any light. LumiBrite-treated hands and markers keep the dial readable after dark, while a screw-down case back and 100-meter water resistance make the HAB001 a genuinely dependable everyday companion, not just a technical showpiece.
The solar-powered movement runs for approximately 6 months on a full charge, and up to 2 years in power-save mode — meaning years of reliable timekeeping with no battery to ever replace.
