Seiko Astron SSH180

Seiko Astron reaches new heights of quality and finishing with the latest GPS Solar Dual-Time Chronograph Introductions. With chronograph timing to 1/20th of a second, the Caliber 5X83 boasts the highest performance in Astron's history. The new watches boast what are among the most sophisticated designs in the Seiko Astron collection. They feature a titanium bezel with a sapphire crystal insert, providing a smooth and elegant detail. The mirror-finishing on the case adds a graceful touch to the powerfully angular shape. The markers on the sub-dials at 12 and 6 o’clock are diamond-cut, giving the watches a refined and striking presence while enhancing legibility in any lighting condition. The main dial features a wide, three-dimensional pattern consisting of horizontal stripes, emphasizing the precision and exactitude of the powerful movement beneath it. Thanks to the low center of gravity of the titanium case and the dual-curved sapphire crystal with super-clear coating, the watches ensure a high level of comfort and legibility. The watches feature a multi-row bracelet with mirror polishing and hairline finishing to achieve a sophisticated look that speaks to the great attention paid to the details. Manufacturing titanium parts with intricate finishing requires tremendous expertise as well as advanced manufacturing technologies. The case back is engraved with a globe that symbolizes the Astron brand's GPS Solar technology, a defining feature of high-end models. The Limited Edition SSH180 forges a powerful presence. The clean look of the sapphire crystal bezel insert combined with the faceted, rose gold-colored titanium bezel provides a radiant quality. Prominent rose gold color accents on the hour markers, bezel, and various other parts of the watch, combined with the deep navy-colored dial, enhances the design by adding a boldness and sophistication all their own. The lustrous black ceramic on the bracelet’s center links furthers the luxurious feel of this limited edition of 1500.
