Grand Seiko 9SA5 Caliber

Introduced in 2020, the Grand Seiko Caliber 9SA5 is their 80-hour, Hi-Beat 36000 (10 beat) movement, which aims to continue to push horological boundaries . With an average time deviation of +5/-3 seconds per day (COSC standards at +6/-4 seconds per day), this movement utilizes several revolutionary innovations to accomplish this. The dual impulse escapement, which regulates the release of energy in the movement, increases the transfer effi ci ency directly from the escape wheel to the balance wheel . Via the mainspring. The twin barrels also allow the 80-hour power-reserve despite the higher rate of beats (which consumes more energy). Additionally , the geniuses at Grand Seiko incorp or ated an overcoil (developed after more than 80,000 simulations) on the mainspring to deliver increased precision and stability. Moreover, the Grand Seiko watchmakers developed a free-spring balan...

Grand Seiko Quartz Movements

The story of Grand Seiko is a long and winding road of countless innovations due to the distance from the remainder of the high-end Western “Swiss” watchmaking manufacturers. Grand Seiko is a manufacturer that remains true to their Japanese identity. They sacrifice nothing to stay true to there inherent values of simplicity, high performing, beautiful watches. As a fully vertically integrated watch manufacturer, they have complete control over their production assembly and still to this day hand assemble their movements, even their quartz movements. Their exceptionally skilled watchmen and women operate in spaces of just 2mm to place the hands of these movements and make adjustments to them within 0.2mm apart so that the watch can operate smoothly. This feature will look into the history of Grand Seiko as it pertains to quartz movements. SBGN005 - The first 9F Grand Seiko quartz watch with a GMT function 1988 – developed, 95GS and exceeded all regular quartz watches by being...

Grand Seiko Hi-Beat 36,000 Movements

The Grand Seiko Hi-Beat 36,000 Since its origin, Grand Seiko quest has been the pursuit of perfection, in terms of design and performance. One such movement that epitomizes this quest is their Hi-Beat 36,000 or “10 beat” movement. In 1960, when Grand Seiko was first created (this year marks their 60 th anniversary), they set out to create an official “Chronometer” in order to compete with the top watchmakers for relevance in terms of precision. 8 short years later, Grand Seiko developed their first 10 beat movement with the 61GS, 45GS and the 19GS (a high precision watch for women). Mechanical Movements and Challenges As a mechanical watch unwinds its mainspring, the gears are turned at a constant rate of oscillation as the balance wheel applies the brake on the gears to precisely rotate the hands while conserving energy. Most high-end watchmakers set this rate at 28,800 vph (vibrations per hour) or 4Hz. 4Hz is equal to 4 oscillations per second or 8 semi-oscillations (...
