This rare Seiko 5 Automatic (Ref. 6309-9000F) carries the distinguished Khanjar emblem of the Sultanate of Oman, printed on its deep navy dial — a detail that marks it as part of a limited batch commissioned during the 1970s and 1980s under Sultan Qaboos bin Said. Such watches were never sold commercially, instead presented as gifts to Omani military officers and visiting dignitaries.

The Khanjar, a traditional curved dagger crossed over two swords, is Oman’s national emblem — a symbol of heritage, honor, and royal patronage. During Sultan Qaboos’ reign, this insignia appeared on a small number of luxury and tool watches produced by brands such as Rolex, Patek Philippe, and Seiko. These timepieces were specially commissioned through the Sultanate’s Ministry of Defense and royal court, meant as tokens of gratitude or diplomatic appreciation. Seiko’s inclusion among these elite manufacturers reflected Japan’s growing prestige in precision watchmaking during that era — an acknowledgment of the brand’s reliability and innovation at a time when quartz technology was reshaping global horology.

The watch houses Seiko’s reliable 6309 automatic movement, featuring a day-date display at 3 o’clock and the classic Seiko 5 layout that became a global standard for precision and endurance. The brushed stainless-steel case retains its original geometry and bracelet, complemented by Seiko-signed clasp and crown. The caseback engraving and reference markings remain crisp, confirming its authenticity and period correctness.

Beyond its mechanical merit, this Seiko Khanjar is a historical object — a quiet witness to the intersection of Japanese engineering and Middle Eastern statecraft, and a rare emblem of an era when watches were more than possessions — they were symbols of trust and diplomacy.
