This model belongs to SEIKO’s iconic “SEIKO 5 SPORTS” series and is equipped with a mechanical automatic movement (Cal. 7S36). No battery replacement is required — the mainspring winds itself as you wear the watch, ensuring stable and continuous timekeeping.

- A Versatile, Uncompromising Design

The approximately 40 mm stainless steel case pairs well with both business and casual attire. Its calm combination of a black dial and silver metal bracelet makes it suitable for any age or style, offering long-lasting appeal.

- Highly Practical Day-Date Display

The day and date display at the 3 o’clock position is convenient for everyday life and business use. The day can be switched between English and Arabic, adding a unique touch characteristic of international models.

- Tough and Reliable 100 m Water Resistance + Unidirectional Bezel

With 10-bar (100 m) water resistance, the watch is safe for daily activities such as exposure to rain, splashes, and hand washing. It also provides peace of mind for light water-related tasks and outdoor use. The unidirectional rotating bezel enhances both its sporty look and functionality.

- The Assurance and Rarity of “MADE IN JAPAN”

This model is manufactured in Japan. Built with high-quality Japanese components, including the automatic movement, it offers outstanding reliability. As production opportunities have decreased in recent years, the watch has become harder to obtain and holds increased collectible value.
