【OH & Exterior Finish Completed】Grand Seiko Second 5722-9991 Hand-Wound Excellent Condition 【Overview】 This is the Grand Seiko Second Model (Ref. 5722-9991), a masterpiece from the early days of Grand Seiko. While inheriting the design of the first model, it features the Cal. 5722A, a hand-wound chronometer movement that offers improved accuracy and durability. This watch perfectly harmonizes the sharp case lines characteristic of the era with the quiet luster of the dial. This particular piece underwent a full overhaul in October 2025. The exterior has also been newly finished, and both the case and dial are in very good condition. The daily rate is +2 seconds, indicating high accuracy and stable operation. 【Condition】 Crystal: Newly replaced (clear visibility) Dial: Excellent condition (almost no aging) Case: Restored and polished / good luster (※some scratches that could not be removed) Belt: Seiko genuine new black genuine leather belt Movement: Cal. 5722A Hand-wound / Fully overhauled (October 2025) Accuracy: Daily rate +2 seconds (measured by timegrapher) 【Specifications】 Brand: GRAND SEIKO Model: Second Model Ref. 5722-9991 Movement: Hand-wound Cal. 5722A Case Material: Stainless steel Case Diameter: Approximately 36mm (excluding the crown) Belt Width: 19mm Production Year: June 1967 【Additional Information】 OH & exterior finish completed, so you can use it with confidence. 【In Conclusion】 I love vintage watches and have a large collection, mainly of Japanese-made watches.
