【Overhauled & Finished】Grand Seiko Chronometer 5722-9990 Hand-Winding 【Overview】 The "5722-9990" is a legendary Grand Seiko model that is essential to understanding the history of the brand. In the late 1960s, Seiko pursued world-class accuracy and released this chronometer-certified model. The sharp lug shape and the heavy case design are truly symbolic of the early GS models. This is a watch where you can feel the honest heartbeat of a mechanical watch, something you can't experience with modern watches. This particular watch has been overhauled and the exterior has been finished. The crystal has been replaced with a new one, providing excellent clarity. The dial is in very beautiful condition, and the case has been carefully polished. Furthermore, the calendar function is working well, and the quick-set function is also operating normally. 【Condition】 Movement: Hand-winding / Overhauled / Daily rate +4 seconds (flat position) Crystal: New replacement / Clear and excellent visibility Dial: Excellent condition (no noticeable stains or dirt) Case: Newly finished / Edges are good Belt: New genuine SEIKO black leather belt installed Calendar: Works well / Quick-set available (some color fading) Fully overhauled, so suitable for daily use! 【Specifications】 Brand: Grand Seiko Reference: 5722-9990 Movement: Hand-winding (Cal. 5722B) Case Material: SS Case Diameter: Approximately 36mm (excluding the crown) Lug Width: 19mm 【Finally】 I love vintage watches and have a large collection, mainly of Japanese-made watches.
