replica Grand Seiko watches – Tentagraph SLGC001
Grand Seiko released the Tentagraph, its first mechanical chronograph.
The Tentagraph is based on the high-frequency Caliber 9SA5 and part of the Evolution 9 series, designed to set a new standard for elapsed time measurement.
Its new caliber 9SC5 oscillates at a high frequency of 5 Hz (36,000 vibrations per hour or 10 vibrations per second) while delivering exceptional power for 3 days even when the chronograph is running.
This performance sets a new industry standard for a 10-beat chronograph with the longest power reserve. This feat is achieved through the use of two barrels and a double-impulse escapement, which efficiently transmits energy from the escape wheel to the free-sprung balance, either indirectly or directly via the pallet fork.high quality watches replica
Each movement is tested for 20 days to ensure compliance with the Grand Seiko standard of +5 to -3 seconds per day.
The name TENTAGRAPH describes its high beat frequency (10 beats per second), long power reserve (three days) and its function (automatic timing graph).
The structure of the movement and its fine finishes can be observed through the case back.
The vertical clutch eliminates any chattering or jumping of the hands when the chronograph is engaged and improves measurement accuracy, while the column wheel provides precise control over the operation of the chronograph. The movement is also equipped with a three-pointed hammer, which ensures that when the reset button is pressed, the hands immediately return to zero and are perfectly synchronized.best replica watches
The Tentagraph has a 43.2mm x 15.3mm high-strength titanium case, which is also used for the three-link bracelet. Alternating finishes of Zaratsu polished and satin-brushed create a non-distorting mirror effect and create a striking visual contrast. A black ceramic bezel with a tachymeter scale completes the bold design of the watch.
Thanks to the screw-down crown, water resistance is guaranteed up to 10 bar (100 meters/330 feet).
The blue dial is protected by a box-shaped sapphire crystal with anti-reflective coating and is decorated with Grand Seiko’s signature "Mt. Seiko" lettering. "Iwate Pattern" was inspired by the ridged silhouette of the nearby mountains that can be seen through the windows of Grand Seiko’s Shizukuishi workshop, where the Tentagraph and all other Grand Seiko mechanical high quality cheap watches are assembled and adjusted by hand. The Mount Iwate dial was created in 2006 First appearing in 1999, the motif has been closely associated with Grand Seiko mechanical watchmaking ever since.
There are small seconds, 12-hour and 30-minute counters at 3 o’clock, 6 o’clock and 9 o’clock respectively. Excellent legibility thanks to the large Lumibrite-filled hands and grooved scales. The chronograph seconds hand curves down slightly towards the dial so that the tip of the hand is as close as possible to the dial markers and extends to the markers on the very edge of the dial.
