SEIKO ROTOCALL RE-EDITION — CALIBER A824

A bold new creation pays tribute to a fan-favorite Seiko digital watch from the 1980s—the legendary Seiko Rotocall. Originally launched in 1982, the Rotocall was celebrated for its distinctive octagonal rotary bezel, a groundbreaking innovation that allowed users to switch modes simply by rotating the bezel.

With its futuristic design, intuitive functionality, and real-world use by astronauts, the Rotocall earned international acclaim and became one of Seiko’s most iconic digital timepieces.

The modern re-edition honors this legacy with faithful aesthetics and upgraded performance, preserving the spirit of the original while enhancing durability, precision, and ease of use.
