1971 36mm Grand Seiko 5641-7000 56GS Hi-Beat 28800bph Automatic Watch Only

A refined example of Grand Seiko’s early 1970s Hi-Beat era, this 5641-7000 is powered by the Caliber 5641A running at 28,800 vibrations per hour. Its clean silver dial and minimalist layout reflect the brand’s pursuit of precision and legibility during a defining period in Japanese watchmaking.
The cushion case offers a distinctive yet wearable profile, balancing vintage character with everyday versatility. As part of the 56GS family, it delivers high-frequency performance in a slimmer, more understated package compared to its contemporaries.
For collectors, this is an accessible entry into vintage Grand Seiko—mechanically robust, historically significant, and effortlessly elegant.
