Seiko Scuba 200m - Vintage Quartz Diver - 5H25-6A1A - 1989 This is a distinctive vintage Seiko Scuba 200m quartz wristwatch, reference 5H25-6A1A, dating to approximately July 1989 based on serial number 970263. The late-1980s Seiko 5H25 Scuba series represents an interesting chapter in Seiko's long history of diver and sports watches. By this period, quartz technology had become firmly established in Seiko's professional and recreational sports-watch development, and the 5H25 series combined quartz reliability with the bold and highly individual styling of the late 1980s. This 5H25-6A1A is one of the more unusual and colourful Seiko Scuba designs from the period. The white dial features large luminous hour markers, a date window at 3 o'clock and an especially distinctive set of bright blue hands. The dial is marked: SEIKO and: SCUBA 200m The combination of the white dial, blue hands and large cream-toned luminous markers gives the watch a striking late-1980s appearance that is very different from more conventional black-dial Seiko diver watches. Surrounding the dial is one of the defining features of this reference: a bold black rotating bezel with large turquoise lettering reading: DIVER SCUBA 200m This highly distinctive bezel gives the watch an unmistakable appearance and is one of the strongest visual characteristics of the 5H25-6A1A. The bezel can be rotated manually. The bezel shows visible scratches, wear and age-related surface marks. Despite this vintage wear, the turquoise lettering remains highly visible and retains the bold character that makes this model so distinctive. Movement and case The watch is powered by the Seiko Cal. 5H25 quartz movement. The watch is running properly at the time of listing. The quartz movement and date function are operating normally. The stainless-steel case back is marked: SEIKO 5H25-6A1A JAPAN D Serial number: 970263 The case back also features the classic Seiko wave emblem, an attractive detail strongly associated with Seiko's diver-watch heritage. Based on the serial number and the known production period of this reference, this example dates to approximately July 1989. Luminous display The luminous material on the hands and hour markers remains active. After exposure to light, the hands and hour markers glow clearly in darkness, as shown in the photographs. In normal lighting, the luminous markers have developed an attractive cream tone with age, contrasting strongly with the bright blue hands and white dial. Strap A new aftermarket black genuine-leather strap has been fitted. Lug width: approximately 20 mm The black leather strap provides a clean presentation and complements the bold black-and-turquoise bezel. Condition The white dial remains clean, attractive and highly legible. The case shows scratches, scuffs and other signs of previous use consistent with a vintage watch. The black bezel shows scratches, wear and age-related surface marks, while its distinctive turquoise DIVER / SCUBA / 200m lettering remains clearly visible. The luminous material has developed natural age-related colour while remaining functional. Please examine all photographs carefully, as they form an important part of the condition description. No box or papers are included. Measurements Case diameter: approximately 38.0 mm, excluding the crown Lug width: approximately 20 mm Important information The watch is running properly at the time of listing. The quartz movement and date function are operating normally. The service history is unknown. The bezel can be rotated manually.

With its bold turquoise “DIVER SCUBA 200m” bezel, bright blue hands, white dial, functioning luminous display, Seiko wave-mark case back and unmistakable late-1980s styling, the 5H25-6A1A is one of the more unconventional and visually memorable vintage Seiko Scuba designs. For collectors looking beyond the familiar Seiko diver references, this 1989 example offers a colourful and distinctive piece from Seiko's quartz sports-watch era.
