Seiko Rotocall Digital Watch SMGG17 Yellow

The Legend Returns. Reimagined for Today.In 1982, Seiko introduced a digital watch so distinctive it became a cult icon — the Rotocall. Its signature feature: a revolutionary octagonal rotary switch bezel that let you change modes with a simple twist of the wrist, no buttons required. It was worn by astronauts, admired by collectors, and remembered by a generation. Now, the Seiko SMGG17 brings that iconic design back to life.The new Rotocall stays true to the spirit of the original — the same satisfying rotating bezel mechanism, the same bold octagonal case presence, now refined in a 37.0mm stainless steel case at just 10.6mm thin. The Quartz Caliber A824 powers a full suite of functions including a 100-hour chronograph to 1/100 second, alarm, dual-time, and battery life warning. At 107g, it wears with the confident heft of a tool watch without the bulk.For collectors who remember the original and enthusiasts discovering it for the first time, the SMGG17 is a rare thing: a piece of horological history you can actually wear every day.Specifications Case Diameter: 37.0mm | Thickness: 10.6mm | Lug-to-Lug: 43.5mm Case Material: Stainless steel | Screw case back Crystal: Hardlex Lug Width: 20mm | Bracelet Length: 195.0mm Clasp: Three-fold clasp with push button release Water Resistance: 10 bar (100m) Weight: 107.0g Movement: Quartz Caliber A824 Precision: ±20 seconds per month Battery Life: Approx. 3 years Functions: Rotary switch, chronograph (100hr, 1/100s), single-time alarm, dual-time, battery life warning Additional Details Brand: Seiko Inspired by the iconic 1982 Seiko Rotocall Rotating bezel for mode switching — no buttons required Favored by astronauts in its original form Authorized DePaula Jewelers dealer
