GRAND SEIKO Evolution 9 Series Tentagraph SLGC001

GRAND SEIKO appeared again at Watches & Wonders Geneva this year, and it continues to bring surprises. The key work is of course the new watch series that was officially renamed from “Series 9” to “Evolution 9” last year. After launching a variety of sports watches for the Evolution 9 series last year, GRAND SEIKO expanded the series again this year, launching the first mechanical chronograph watch Tentagraph SLGC001, setting a new milestone.

SLGC001/titanium material/9SC5 self-winding movement/hour, minute, small second, date display/chronograph function/sapphire crystal mirror, transparent bottom cover/waterproof 100 meters/diameter 43.2mm.

From the name, you can feel that SLGC001 is not simple. After all, GRAND SEIKO has created a new word for this watch – “Tentagraph”. So, how to understand this name? The official answer given by the brand is: “Ten beats per second” + “Three days” + “Automatic chronograph”, from which “Tentagraph” is formed, which represents the high vibration frequency, long kinetic energy and automatic timing function of the watch.

From the perspective of the movement, this watch is indeed very unusual, because SLGC001 is equipped with a new model of the 9S movement series-9SC5 movement. The 9SA5 movement, as the first model of the new generation 9S series, debuted in early 2020. It has a variety of revolutionary features such as Dual Impulse Escapement, cardless balance spring, double barrel, high vibration frequency, etc. new features. The 9SC5 movement also inherits these characteristics, equipped with an energy-saving escapement and two barrels, with a power reserve of 72 hours; a vibration frequency of 36,000 times per hour, 10 times per second; an accuracy of +5 to -3 seconds per day; The vertical clutch, column wheel and three-pointed hammer are adopted to ensure that when the reset button is pressed, the hands return to zero immediately and synchronously. replica automatic watches

This movement has also undergone a new testing procedure which is longer than normal standards. Like all mechanical movements of the brand, the time accuracy of Tentagraph was tested at six positions and three temperatures for seventeen days, and the accuracy was tested at three positions with the chronograph mode turned on for an additional three days. Therefore, each Tentagraph movement is tested for a total of twenty days. Even in the timing mode, SLGC001 can continue to operate for three days, and it is currently the chronograph with the longest power reserve in the industry that can vibrate ten times per second (from the brand’s research report as of March 2023).

Turn to the back of the watch to appreciate the 9SC5 self-winding movement on board. This movement has a diameter of 33mm, a thickness of 8mm, a power reserve of 72 hours, and the number of gems is 60. The watch body is decorated with Zaratsu ultra-mirror finish, zero-distortion mirror surface and delicate hair texture alternately, creating a softer and more refined temperament. The black bezel ceramic not only visually highlights the dial, but also protects the watch from scratches and is more durable.

In addition to its extremely reliable performance, the appearance of SLGC001 has also been carefully modified and designed by GRAND SEIKO, making it both internal and external. As a new work of the Evolution 9 sports watch series, the original style of the series is presented on the watch. The case and bracelet are made of high-strength titanium metal, which is about 30% lighter than stainless steel and more scratch-resistant, and is decorated with black Bezel ceramic. The body of the watch is also decorated with Zaratsu ultra-mirror finish, zero-distortion mirror surface and exquisite hair texture alternately, making the surface intertwined with light and shadow, full of exquisite texture. cheap replica watches

GRAND SEIKO has always added different creativity and poetry to the dial, and this time is no exception. The calm dark blue dial is decorated with intricate textures, which originate from the outline of the Iwate Mountain ridge seen outside the Shizukuishi workshop of the brand. In fact, as early as 2006, the brand created this Mount Iwate dial. Since then, this dial texture has formed an indissoluble bond with GRAND SEIKO, and the majestic mountain is also the enduring source of inspiration for GRAND SEIKO. This time, the dial is specially combined with a soft dark blue tone, which is further reminiscent of the night sky on Mount Iwate.

The dial’s intricate texture, grooved hour markers and recessed sub-dials add visual depth and legibility. The hands and hour markers are covered with Lumibrite environmentally friendly light-storing paint to further improve the readability at night.

The dial has a small seconds dial at 3 o’clock, a 30-minute counter at 9 o’clock, and a 12-hour counter at 6 o’clock. The characteristic sword-shaped hands and grooved hour markers of the series can also be seen on it. The minute hand is in a soft arc shape, and the chronograph second hand is also slightly curved towards the dial. The hands and hour markers are covered with Lumibrite environmental protection light-storing paint, and the time is clear by engraving details easy to read. Wholesale Fake Discount watches
