Official description

Today, the ritual of winding a watch is one of life’s pleasures. The simple act of turning the crown taps into the senses to forge a deeper connection with time’s natural flow. In the 1960s and ’70s, manually wound 10-beat Grand Seiko creations were manufactured in the pursuit of better rate stability and higher precision. This year, for the first time in more than 50 years, Grand Seiko announces a new hand-wound high-beat movement, the Caliber 9SA4. It is the third movement to join the latest generation of the mechanical Caliber 9S platform, which was born in 2020 with the automatic Caliber 9SA5 and then followed just last year with the Tentagraph Caliber 9SC5 chronograph.
