Description

This Seiko 5 Sports Automatic Diver (ref. 4R36-0820) is a modern Japanese sports watch that combines the robustness of a tool diver with the everyday versatility for which the Seiko 5 line is famous. The stainless steel case (approx. 42 mm) and matching mesh bracelet give the watch a contemporary and sporty presence on the wrist, while remaining comfortable enough for daily wear.

At the heart of the watch beats Seiko’s reliable automatic calibre 4R36 with hacking and hand-winding functions. With 24 jewels and an approximate 40-hour power reserve, it is designed as a durable, low-maintenance movement ideal for an everyday sports watch. The transparent case back allows you to appreciate the mechanical movement in action.

The champagne / light gold dial is particularly striking, with bold luminous markers and hands providing excellent legibility in low light. The black unidirectional rotating bezel frames the dial and reinforces the diver’s aesthetic, offering practical timing capability for sports and daily activities. A day-date window at 3 o’clock adds functionality, with both the day and date clearly displayed.

With 10 bar (100 m) water resistance indicated on the case back, this Seiko 5 Sports is well suited to everyday use, from city life to weekend activities, while the mesh bracelet gives it a slightly dressier twist that pairs well with casual or smart-casual attire.

Overall, this is an attractive, near-mint example of a modern Seiko 5 Sports diver, ideal for collectors of Japanese watches or anyone seeking a dependable automatic sports watch with a distinctive dial and strong wrist presence.
