As the international reputation of Grand Seiko continues to grow, watch lovers worldwide have asked for the women’s range to be expanded. Their request is now met with the launch of an allnew automatic caliber. It is presented in a limited edition of quite exceptional beauty.
The new caliber is designed to offer both a slim profile and a high level of performance. It is just 4.49 mm in height, allowing the case to fit every wrist while it also has the strength to deliver a 50 hour power reserve and a precision of +8 to -3 seconds a day, which is a tangible tribute to the innovative engineering. Caliber 9S25 uses Grand Seiko’s most advanced technologies, including the latest 610 alloy for the balance spring and MEMS engineering for the pallet fork, escapement wheel and other key components. The gear train layout is entirely new as is profile of the teeth on each gear to ensure maximum energy efficiency. The escapement wheel has a new design that is lighter but still robust and designed for maximum durability. It is an 8 beat caliber with 33 jewels.
Like all other Grand Seiko mechanical watches, this watch is made and assembled by hand at the Shizukuishi Watch Studio in Morioka. No compromise is made at any stage; each 9S25 movement is put through the same rigorous 17 day testing procedure as every men’s Grand Seiko mechanical watch.
Through the sapphire case back, the beauty of the new caliber and the painstaking care taken over its finishing shine bright. The beauty of the craftsmanship is much more than skin deep.
Hidden within the movement is the escapement wheel which is made in the shape of a five-petal flower and, beneath the oscillating weight, the elegant lines of the bridges flow like a stream that can be glimpsed as the weight moves back and forth. Similarly, the additional strap has a white textured surface with a grosgrain pattern but behind it lies a second and hidden layer, made of the finest crocodile leather.
In every aspect, both exterior and interior and both visible to the eye and hidden within, this remarkable jewel of a watch exemplifies the high quality watchmaking for which Grand Seiko is renowned. At each glance of the brilliant dial, it is a joy to behold but it also offers its owner the inner satisfaction of knowing that the external beauty is matched by the internal quality and craftsmanship with which every component is made and assembled.
he dial is both striking and subtle. Its rich look is achieved with silver lamé that creates the sensual texture of the snow on Mt Iwate that overlooks the Shizukuishi studio where the watch is made. The bezel features 37 diamonds set into the 18k case with 60 diamond-cut facets. One larger diamond is set into the crown and eleven more mark the hours on the dial. This watch is offered in a limited edition of 50 and will be available in July.
