The "KSK" series, which has been in existence since the collection’s revival in 2022, is now available in a simple three-hand design with a 36.1mm case, the smallest of the current King Seiko models. The case has mirror polishing and hairline finishing to create a compact yet sharp design with prominent ridges, a characteristic of the "KSK" series.

Ivy style originated on the East Coast of the United States in the 1950s and developed uniquely in Japan in the 1960s, when King Seiko was born. The dial color is ivy green, the accent color of the regimental ties that decorated the Ivy League look. The gold-colored seconds hand adds a traditional touch, while the Lumibrite on the hour hand, minute hand, and indexes has a patinated appearance that harmonizes with the dial.

The metal bracelet features a simple double-lever system, allowing it to be easily attached and removed without the use of tools. Combining the bracelet with leather straps (sold separately) greatly expands the range of coordination.
Running on the mechanical Caliber 6R51, the watch has a power reserve of three days. Fully wound, the watch can be removed on a Friday and worn the following Monday without any need for winding.
