Grand Seiko - Evolution 9 Spring Drive SLGA021
Grand Seiko has added a new reference to its Evolution 9 series: the Spring Drive SLGA021.
This three-hand model features a blue dial inspired by the gentle waves of Lake Suwa, located southeast of the Shinshu Watch Studio where Grand Seiko designers developed the spring Drive models.
Matching the 40mm x 11.8mm faceted stainless steel case, the box-shaped sapphire crystal incorporates Grand Seiko’s Zaratsu polish and hairline finishing to accentuate its dynamic lines. Thanks to the screw-down crown, water resistance is guaranteed up to 10 bar (100 meters/330 feet). replica watches for sale
Model SLGA021 is powered by Spring Drive Caliber 9RA2, which offers an exceptional 120 hours (5 days) power reserve when fully wound, and improved accuracy to ±0.5 seconds per day or ±10 seconds per month. To make the dial simpler, the power reserve indicator has been moved to the back of the watch.
The new Grand Seiko Evolution 9 Spring Drive SLGA021 comes with a stainless steel bracelet and a three-fold clasp.
Grand Seiko - Tentagraph SLGC001
Grand Seiko releases the Tentagraph, its first mechanical chronograph.
Based on the high-oscillation Caliber 9SA5 and part of the Evolution 9 series, the Tentagraph is designed to set new standards in elapsed time measurement.
Its new 9SC5 movement vibrates at a high frequency of 5 Hz (36,000 vibrations per hour or 10 vibrations per second) while delivering an exceptional 3 days of power even when the chronograph is running. Best watches for men 2023
This performance sets a new industry standard for the 10-beat chronograph with the longest power reserve. This feat is achieved through the use of two barrels and a double-pulse escapement, which efficiently transmits energy from the escape wheel to the free-spring balance, either indirectly through the pallet fork or directly.
Each movement is tested for 20 days to ensure it meets Grand Seiko's 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 chronograph GRAPH).
The structure of the movement and its exquisite finishes can be observed through the case back. replica Richard Mille
The vertical clutch eliminates any judder or jump in the hands when the chronograph is engaged and improves measurement accuracy, while the column wheel provides precise control of the chronograph operation. The movement is also equipped with a three-pointed hammer, ensuring that when the reset button is pressed, the hands immediately return to zero and are perfectly synchronized.
The Tentagraph is housed in a 43.2mm x 15.3mm high-strength titanium case, which is also used on the three-link bracelet. The alternating Zaratsu polished and satin-brushed finishes create a mirror-like effect that does not distort and creates a striking visual contrast. A black ceramic bezel with tachymeter scale completes the bold design of the watch.

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. The "Iwate Pattern" was inspired by the ridged outline of the nearby mountains that can be seen through the windows of Grand Seiko's Shizukuishi studio, where the Tentagraph and all other Grand Seiko mechanical watches are assembled and adjusted by hand. The Iwate Mountain Dial was created in 2006 First appearing in 1998, this pattern has since been closely associated with the Grand Seiko mechanical watchmaking industry.
There are small seconds counter, 12-hour counter and 30-minute counter at 3 o'clock, 6 o'clock and 9 o'clock respectively.
Legibility is excellent thanks to the large hands and fluted indexes filled with Lumibrite. The chronograph seconds hand curves slightly downward toward the dial, bringing the tip of the hand as close to the dial mark as possible and extending to the mark on the very edge of the dial. replica Jacob & Co.
