Seiko Selection S Series Octagonal Digital Quartz “Rotocall” Re‑Creation SMGG19
Step back into the golden era of digital innovation with Seiko’s latest tribute to one of its most daring designs. The SMGG17/19/21 re‑imagines the legendary 1982 “Rotocall” — a watch that broke boundaries with its futuristic octagonal case and pioneering rotary bezel.
A Revolution in Design The original Rotocall was more than just a digital watch; it was a bold experiment in functionality. By simply rotating the bezel, wearers could switch modes with ease — a concept that felt decades ahead of its time. This ingenious feature, paired with its striking geometric silhouette, made the Rotocall an instant icon.
A Legacy Beyond Earth Beloved not only on Earth but also among astronauts, the Rotocall earned international recognition as a symbol of precision and reliability. The SMGG17/19/21 carries forward that spirit, blending nostalgic charm with modern quartz technology for today’s collectors.
