Rare Vintage Seiko LifeSports W772-0AA0 Vibration Alarm Digital Sports Watch JDM

For sale is an extremely rare vintage Seiko LifeSports W772-0AA0 referee digital sports watch from the early 1990s — a Japan-Domestic-Market (JDM) model designed specifically for timing sports events and matches. This model is notable for its vibration alarm ring, a feature that allowed referees to receive silent alerts during games — an advanced and unusual function for its era. The watch is in full working condition, and all features operate correctly, including the vibration alarm, digital time display, chronograph, and mode functions. The strap, buckle, module, and caseback are completely original Seiko components. The watch remains in very good physical condition overall, with only the most minimal signs of prior use. The resin outer shell does show some natural aging — common on LifeSports models — but the watch remains structurally sound and comfortable to wear.
