GRAND SEIKO | Spring Drive U.F.A. opens a new chapter of ultra-precision
The pursuit of high precision has always been the core spirit of the GRAND SEIKO brand. In 2004, the 9R series was launched, successfully combining the precision of electronic timekeeping and the perpetual power of mechanical springs. This year, GRAND SEIKO launched the Spring Drive Caliber 9RB2 movement, which has won the new U.F.A. (ULTRA FINE ACCURACY) title. Its accuracy is ±20 seconds per year, making it the most accurate spring-driven watch movement today. high quality replica watches
The quiet revolution in the history of watches was created in 1977 by Mr. Akabane Yoshikazu, a watchmaker at Suwa Seikosha (now Seiko Epson). He dreamed of creating a watch that combined the precision of electronic timekeeping and the perpetual power of mechanical springs. After more than 20 years of development, it was finally achieved in 2004 with the 9R series. The smooth running second hand of Spring Drive reflects the natural, silent and continuous flow of time. Spring Drive has become GRAND SEIKO's unique way of expressing "The Nature of Time".
Less than 10 years after the birth of its first watch, GRAND SEIKO launched the V.F.A. mechanical movement, accurately interpreting "Very Fine Adjusted". The name was first used in 1969, meaning that GRAND SEIKO watches are finely adjusted, with an extremely excellent accuracy of ±1 minute per month, defining the concept of precision of GRAND SEIKO watches. In the early days of Spring Drive development in the 1970s, the aim was to perfectly combine traditional spring power with advanced electronic watchmaking technology. Finally, in 2004, the Spring Drive 9R65 movement was launched, which has the charm, beauty and soul of traditional mechanical watchmaking, while achieving the precision of modern electronic watchmaking, combining automatic winding and 72 hours of power reserve, and has superb technology with a monthly error of ±15 seconds.
This year, GRAND SEIKO launched the Spring Drive Caliber 9RB2 movement, which has been awarded the new U.F.A. title, raising the precision of watchmaking to a new level. The 9RB2 movement has a new U.F.A. name, which stands for the ultra-high precision definition of "ULTRA FINE ACCURACY". This groundbreaking movement has an accuracy of ±20 seconds per year, making it the most accurate spring-driven watch movement today. * Thanks to the miniature design of this movement (30.0mm in diameter and 5.02mm in thickness), the watch it is equipped with is only 37mm in diameter and 11.4mm in thickness, making it the smallest 9R series model to date. replica luxury watches
The Spring Drive U.F.A. movement has an ultra-high accuracy of ±20 seconds per year, thanks to the three-month-old quartz oscillator and integrated circuit (IC) using a new and improved manufacturing and processing method. As with the Spring Drive caliber 9RA series, the frequency of each individual quartz oscillator is measured at three different temperatures, and the final data is input into a low-power integrated circuit for temperature compensation. The oscillators and sensors are vacuum-encapsulated to minimize temperature differences and avoid the influence of external factors (such as humidity, static electricity and light), ensuring precise temperature regulation and stable performance of the quartz oscillator. In addition, the new 9RB2 movement is the first in the Spring Drive series to be equipped with an adjustment function for the first time. This function can be used to correct the accuracy errors that may be caused by long-term wear and use during after-sales service.
GRAND SEIKO's unique movement aesthetics are displayed through the sapphire crystal back cover, and the mirror-polished chamfered edges add to the bright brilliance of the movement. The overall design is inspired by the natural environment s
