SEIKO AGS SCUBA 200m 5M23-6B40 Titanium Kinetic Day-Date Blue Dial Vintage Watch

Introduction

This Seiko AGS Scuba 5M23-6B40 is a distinctive Japanese sports watch combining Seiko’s self-generating quartz technology with a lightweight titanium case and bracelet.

The watch features a dark blue dial, large luminous-style hour markers and hands, a day-date display at 3 o’clock, and a bold diver-style bezel. The titanium construction and functional sports-watch design give this model a characteristic vintage Seiko appearance.

Historical & Collector Value

Seiko has a long history of developing innovative quartz technology, and the AGS system represents an important stage in the evolution of the brand’s self-generating watches.

AGS uses the movement of the wearer’s wrist to rotate an internal rotor, generating electrical energy that is stored to power the quartz movement. This differs from a conventional mechanical automatic watch. The technology later became widely known under Seiko’s Kinetic name.

Vintage AGS and early Kinetic models are increasingly interesting to collectors because they represent a distinctive period in Seiko’s technical development. This example combines the 5M23 movement with a titanium diver-style case, day-date display, 200 m markings, and an integrated titanium bracelet.

It is not presented as a limited edition, but its unusual self-generating movement technology, titanium construction, and unmistakable 1990s-era sports design give it strong period character.

Condition

This is a used vintage watch. The titanium case, bezel, case back, bracelet, clasp, crown, and push button show scratches, rubbing, small marks, and general wear consistent with age and previous use.

The bezel markings show age-related wear. The dark blue dial, hands, hour markers, and day-date display remain clearly visible. The case back also shows scratches and wear from previous use.

The watch is running at the time of listing. Detailed testing of daily accuracy, charging efficiency, rechargeable cell condition, power reserve, long-term operation, and all functions has not been carried out.

Because this model uses a rechargeable AGS / Kinetic-type system, the condition and remaining capacity of the internal rechargeable cell are unknown. Professional inspection or replacement of the rechargeable cell may eventually be required.

Please examine all photographs carefully for the exact cosmetic condition.
