King Seiko SPB365 110th Anniversary Limited Edition: A Commemorative Timepiece with a Captivating Turtle Shell Dial

Get ready to dive into the fascinating history of Seiko as we unveil the King Seiko SPB365, a special edition watch crafted to celebrate the brand's remarkable 110-year journey. Back in 1881, Kintaro Hattori opened a shop in Ginza, marking the birth of Seiko and its commitment to repairing and selling timepieces. Fast forward to 1913, and Seiko proudly introduced Japan's first wristwatch, the Laurel, kickstarting a series of groundbreaking advancements in watchmaking. Among these achievements was the iconic King Seiko, originally launched in 1961, and now reborn in a modern interpretation.

The King Seiko SPB365 draws inspiration from the historic Kameido district in Tokyo, known as the birthplace of King Seiko. Its fascinating shape, reminiscent of a turtle shell, has inspired a captivating textured pattern on the dial. Bathed in a rich dark brown hue, the dial beautifully harmonizes with the turtle shell motif, exuding an aura of timeless elegance.

This remarkable timepiece pays homage to its ancestor, the 1965 KSK model, renowned for its sharp angles, flat dial, faceted indices, and distinctive razor-edged hands. Embracing the vintage vibe, the King Seiko SPB365 features a compact 37mm stainless steel case, faceted lugs with a mirror-polished and hairline finish, a beveled bezel, and a box-shaped sapphire crystal. The seven-link stainless steel bracelet, with its brushed and polished facets, closely mirrors the original design. As a bonus, an additional leather strap sourced from LWG-certified sustainable tanneries is included, ensuring versatility and style.

The highlight of this commemorative timepiece is the special dial design, inspired by the captivating Japanese geometric pattern known as "kikkoumon." This hexagonal motif symbolizes a tortoise shell, reflecting strength and victory, reminiscent of the armor worn by legendary samurai warriors. The dial boasts a stunning degradé effect, transitioning from a vibrant inner section to a deeper shade towards the outer perimeter. Complementing the overall aesthetic are the gold-colored Seiko logo and the almost bronze-colored seconds hand, perfectly matching the dauphine hands and hour markers.

Powering the King Seiko SPB365 is the automatic winding, in-house Calibre 6R31, expertly assembled by Seiko's skilled craftsmen and women. With 24 jewels, a frequency of 21,600vph, and an impressive power reserve of 72 hours, this timepiece ensures accurate and reliable timekeeping. It doesn't stop there! With a water resistance of 100 meters, the King Seiko SPB365 is ready to accompany you on any adventure. Choose between the sleek stainless steel bracelet or the supple leather strap, both designed to provide comfort and style.

Wearing the King Seiko SPB365 is an experience in itself. The meticulously finished case, the seamless integration of the bracelet, and the eye-catching details, such as the gold logo and the bronze-toned seconds hand, come together to create a sophisticated and captivating timepiece. So, get ready to embrace the enduring legacy of Seiko with the King Seiko SPB365, a limited edition watch that effortlessly blends history, style, and exceptional craftsmanship.
