The Skeie's Difference

Family-Owned Since 1922
Complimentary Shipping

The Grand Seiko SLGB007 brings together exceptional Spring Drive accuracy, lightweight titanium construction, and one of Grand Seiko's most atmospheric dial designs. Its textured black dial is inspired by the surface of Lake Suwa at night, with a warm black gradation and radial pattern recreating gentle ripples reflecting moonlight.

Inside is Grand Seiko's Spring Drive U.F.A. Caliber 9RB2, delivering extraordinary accuracy of ±20 seconds per year and approximately 72 hours of power reserve. A 40mm High-Intensity Titanium case and matching bracelet keep the watch remarkably light on the wrist while maintaining the refined finishing expected from Grand Seiko.

The Skeie’s Perspective

The dial may be what first gets your attention, but Caliber 9RB2 is what makes the SLGB007 particularly important.

Grand Seiko's U.F.A.—Ultra Fine Accuracy—designation represents a different standard for Spring Drive precision. Instead of discussing accuracy in seconds per day, Grand Seiko rates this movement at just ±20 seconds over an entire year.

We also love how wearable Grand Seiko has made the watch. At 40mm and only 110 grams, the High-Intensity Titanium construction gives the SLGB007 substantial wrist presence without substantial weight. Add the new micro-adjustable bracelet, and this becomes a technically remarkable Grand Seiko that is also exceptionally practical to wear.

Lake Suwa by Moonlight

Lake Suwa has inspired several memorable Grand Seiko dials, but the SLGB007 interprets it after dark.

The dial combines a warm black gradation with a radial texture to evoke the softly rippling surface of the lake reflecting moonlight. Against it, the continuous glide of the Spring Drive seconds hand reinforces the sense of calm movement that inspired the design.

The result is a black dial with considerably more depth and character than its color alone might suggest.

Spring Drive U.F.A. Caliber 9RB2

U.F.A. stands for Ultra Fine Accuracy, and Caliber 9RB2 achieves an exceptional stated accuracy of ±20 seconds per year, or approximately ±3 seconds per month.

The self-winding Spring Drive movement can also be wound manually and provides approximately 72 hours of power reserve when fully wound. A power-reserve indicator is incorporated into the movement, preserving the clean appearance of the dial.

High-Intensity Titanium

Both the case and bracelet are crafted from Grand Seiko's High-Intensity Titanium, offering a brighter appearance and greater scratch resistance than conventional titanium while retaining titanium's corrosion resistance and lightweight comfort.

The completed watch weighs approximately 110 grams, around 30% lighter than a comparable stainless-steel construction.

A tapered bracelet is finished with a three-step micro-adjustment clasp, allowing up to 6mm of tool-free adjustment in precise 2mm increments.

We offer complimentary shipping on all orders, with each piece carefully packaged and fully insured for delivery. For full details on shipping methods and timelines, please visit our Shipping Policy.

Articles may be returned for a refund or exchange within 30 days of purchase, provided they are in salable condition and accompanied by a valid sales receipt. Please note that some exclusions may apply. For complete return guidelines, visit our Returns Policy.
