【Description】 The Seiko Astron was born from the idea of receiving time information from GPS satellites so that it can display the correct local time anywhere on earth. This piece features a black ceramic bezel marked with world time city codes, with the inner ring engraved with the offset from UTC — a composition characteristic of the Astron. The dial is based on black, combining red markers, white indexes, and multiple sub-dials into a three-dimensional layout. Despite the amount of information presented, the white indexes and hands form a strong contrast against the black dial. The case is stainless steel, and the bezel is made of ceramic. Ceramic is a hard material that resists changes in luster caused by everyday rubbing. The crystal is a sapphire crystal with a special coating. The movement is solar powered. Because it generates power from light, it will not stop as long as it is worn regularly. It features a date display and acquires the time via its GPS reception function. The bracelet is a genuine stainless steel bracelet. With a substantial case width of 45mm, it pairs with everything from jacket styles to casual wear. It is a watch designed with travel and business trips across time zones in mind. 【Specifications】 Brand: SEIKO Model: Astron Reference Number: 8X53-0AD0-2 Serial Number: 540617 Movement: Solar (light-powered) Case Material: Stainless Steel with Ceramic Bezel Crystal: Specially Coated Sapphire Crystal Dial Color: Black Functions: Date Display, GPS Reception Bracelet: Genuine Stainless Steel Bracelet 【Size】 Case width: 45mm (excluding crown) Lug width: 22mm Maximum wrist size: 160mm Spare links: None 【Condition】 The front and sides of the case have some slight scuffs from use and small dents.
