Description
The Seiko Astron HAB004J is the second-installment limited model of Seiko's 145th Anniversary collection, introducing the newly developed Caliber 5X63 — a GPS Solar dual-time chronograph finished in a fresh "Seiko Blue" colorway inspired by the brand's iconic 1960s house blue. The new caliber arranges three sub-dials at the 3, 6, and 9 o'clock positions, giving the dial a clean, technical chronograph layout in white-on-blue. A special dual-color silicone strap — blue and white, matched to the dial — ships alongside the standard bracelet, and Seiko's proprietary Smart Switch mechanism lets you swap between them with a single push, no tools required. World limited to 2,000 pieces (800 domestic). Seiko Global Brand Core Shop exclusive.
Key Features:
- GPS Solar Caliber 5X63 — Dual-Time Chronograph, World Time, Perpetual Calendar: Solar-powered with GPS satellite radio-wave time correction. Features dual-time display, 1/20-second chronograph with 24-hour counter, world time across 38 timezones, and perpetual calendar valid to February 28, 2100.
- Pure Titanium Case with Dia-Shield Coating: Lightweight, scratch- and allergy-resistant titanium case construction, finished with Seiko's Dia-Shield surface treatment.
- Seiko Blue Dial with Sub-Dial Chronograph Layout: A tri-compax dial design (3/6/9 sub-dials) finished in the historic "Seiko Blue" tone first established in the 1960s — the same era that saw many of Seiko's foundational technical breakthroughs.
- Smart Switch Quick-Change Strap System: Includes a color-matched blue-and-white silicone strap in addition to the standard bracelet, swappable via Seiko's tool-free Smart Switch mechanism.
- Sapphire Crystal with Super Clear Coating: Scratch-resistant sapphire crystal treated with anti-reflective coating for maximum dial legibility.
