Seiko Scuba 200m Ref. 5H25-6060 A0 - March 1990, NOS
A diver's watch with a white dial offers something different from black-dialed versions: it gives the technical structure a lighter appearance while making the bezel, hands, and luminous markers stand out more prominently. The Seiko Scuba 5H25-6060 A0 embodies this clean, functional approach characteristic of the early 1990s within its compact, approximately 37mm case.

The serial number "030195" on the case back dates the watch to March 1990. The reference "5H25-6060 A0" visible on the same case back indicates the model's specific case code. The inscription "JAPAN 5H25-602L T3" at the bottom of the dial represents the dial production code. The case back also specifies the battery type as SB-AN / SR920SW; thus, this model is not an AGS or Kinetic watch but runs on the standard 5H25 analog quartz movement.
The "SCUBA 200m" text on the dial, the large luminous indices, the screw-down crown, and the unidirectional rotating dive bezel clearly highlight the watch's tool-watch character. While the light-colored dial shifts from silver to white depending on the lighting, the dark-framed hands create a strong contrast. The bezel, featuring a wide grip surface, integrates its functionality directly into the design.
The most remarkable aspect of this particular piece is its condition. It is NOS (New Old Stock); the case, bezel, and original steel bracelet have been preserved in unused condition. The bracelet suitable for wrists up to approximately 19.5 cm and the Seiko signed clasp complement the watch's original character. The luminous material on the indices, hands, and bezel triangle still reacts distinctly to light.
Powering the watch is the Seiko Calibre 5H25, a 3-jewel analog quartz movement designed for daily use. Its battery life of approximately three years and accuracy rating of ±15 seconds per month reflect the practical approach Seiko took with its quartz sports watches of that era. The Hardlex crystal is also a fitting choice for a model intended for daily, sporty use.
The accompanying black zippered case is not part of the original Seiko set; it was added later to ensure safe transport.
The "200m" marking on the dial indicates the water resistance rating from the time of the watch's manufacture.
Final Thoughts
The most interesting aspect of this Seiko Scuba isn't that it houses a rare movement, but rather that a genuine 200-meter sports watch built to be worn has remained unused for nearly 36 years. Dating from March 1990, this NOS (New Old Stock) example preserves one of Seiko’s functional quartz-era dive watches in near-original condition, featuring a light-colored dial, a compact 37mm case, its original steel bracelet, and still-vibrant lume.
