Relive the technological optimism of the 1980s with the Seiko Classic Digital Watch SMGG17. This timepiece is a faithful reissue of the iconic 'Rotocall' model (A829), renowned for being the unofficial watch of astronauts due to its innovative interface.
The watch's centerpiece is its octagonal rotating bezel, which allows you to switch between eight core functions (including chronograph, dual time, and alarms) by simply turning it—a feature ideal for use with gloves or minimal fuss. It is powered by the reliable Caliber A824 quartz movement, housed in a durable 37mm stainless steel case. With 10 bar (100m) water resistance and a strong Hardlex crystal, the SMGG17 is a true, robust tool watch built for both nostalgia and daily performance
