Seiko Astron GPS Solar Speed of Light Limited Edition SSH185

The Speed of Light. Limited to 1,200 Pieces.Light travels at 299,792 kilometers per second — a speed so extraordinary that it bends our understanding of time itself. The Seiko Astron SSH185 captures that energy in a watch that looks like it's already moving. The dial features a new horizontal pattern with intermittent lines, evoking the visual sensation of light streaking at high speed — the same bold, dynamic design language as the SSH183, rendered in a strikingly different palette.Light green accents punctuate the case and details throughout, delivering a fresh, futuristic aesthetic that feels both sporty and sophisticated. The two-toned titanium-and-white-ceramic construction gives this piece a distinctive identity within the Speed of Light series — the contrast of black hard-coated titanium against white ceramic creating a look that is unmistakably its own. Powered by the GPS Solar Caliber 5X83, it self-adjusts to atomic clock accuracy via satellite and runs for approximately 6 months on a full charge. The 43.4mm titanium case keeps it light and durable. Each piece is individually numbered. Only 1,200 pieces exist.Precision at the speed of light. In a different light.Specifications Case Diameter: 43.4mm | Thickness: 13.4mm | Lug-to-Lug: 49.5mm Case Material: Titanium with black super-hard coating | Ceramic/aluminum bezel Crystal: Dual-curved sapphire with super-clear coating Bracelet: Titanium with black super-hard coating + white ceramic | Lug Width: 14mm | Length: 190.0mm Dial: Horizontal speed-of-light pattern | Light green accents Water Resistance: 10 bar (100m) Magnetic Resistance: 4,800 A/m Movement: GPS Solar Caliber 5X83 Precision: ±15 sec/month (without GPS signal) Power Reserve: Approx. 6 months (fully charged) | 2 years (power save) Functions: GPS time adjustment, world time (38 cities), dual-time, chronograph (12hr), perpetual calendar, day, power reserve indicator, DST, in-flight mode Weight: 123.0g Reference: SSH185 Additional Details Brand: Seiko | Collection: Astron Limited Edition: 1,200 pieces worldwide | Individual serial number on case back Nickel-free construction LumiBrite on hands and indexes Authorized DePaula Jewelers dealer
