Remember when watches went to space? The Seiko Rotocall just made a spectacular comeback, and it's bringing intergalactic credentials with it. This isn't just another retro reissue – it's a faithful revival of the actual timepiece worn by NASA astronauts on over 160 space shuttle missions, chosen personally by legends like Sally Ride for its brilliant, glove-friendly design.
Discover the Seiko Rotocall collection, a faithful reissue of the 1980s astronaut watch with an innovative eight-function rotating bezel. These 37mm digital timepieces feature the A824 quartz module, 100m water resistance, and come with a stainless steel bracelet for versatile wear.

🚀 A Space-Faring Legend Returns
The Seiko Rotocall is not just a watch; it's a piece of space exploration history. The original model, first released in 1982, earned the nickname "the Astronaut" after being chosen by numerous space shuttle crews for their personal use. Notably, it was worn by pioneers like Sally Ride, the first American woman in space, and Kathryn Sullivan. Despite never being official NASA-issued equipment, its presence on over 160 missions cemented its legendary status. Seiko has now faithfully revived this icon, bringing its unique bezel-controlled functionality and retro-futuristic aesthetic to a new generation.
⌚️ Modern Specs, Classic Proportions
The new Rotocall stays true to the original's wearable 37mm stainless steel case but enhances it with modern materials and improved performance. The following table summarizes its core specifications:
At the heart of the watch is the Seiko Caliber A824 digital quartz movement, which offers a 1/100-second stopwatch that can measure up to 100 hours, a dual-time function, and multiple alarms. The 100-meter water resistance makes it far more capable than a typical digital watch, suitable for swimming and snorkeling.
✨ The Defining Feature: The Rotating Bezel
What truly sets the Rotocall apart is its innovative octagonal rotating bezel, which Seiko calls a "rotary switch". This brilliant design eliminates the need to fumble with tiny buttons to change modes.
Intuitive Operation: Simply turn the bezel to align one of its eight labeled sides with the marker at 12 o'clock. This instantly selects functions like Time, Stopwatch, Timer, Dual Time, and Alarms.
User-Friendly Interface: This tactile, mechanical interface was particularly valued by astronauts, as it was easy to operate even while wearing gloves.
🎨 Model Variants & Aesthetic Details
Seiko is releasing the Rotocall in three colorways, each echoing the original 1980s palette. The watches come on a five-row stainless steel bracelet with a push-button release clasp.
| Model Reference | Color Scheme | Key Aesthetic Features |
|---|---|---|
| SMGG17P1 | Yellow & Black | Black dial, yellow and black aluminum indicator ring on bezel. |

💡 Why the Rotocall Reissue Matters
The return of the Rotocall is significant for several reasons. It’s a faithful reissue that preserves the original's design language without unnecessary modernization. Unlike many retro-inspired releases, it has been announced as part of Seiko's permanent catalog, making it accessible without the pressure of a limited edition. Priced around $664 SGD, it offers a unique combination of space history, innovative design, and solid build quality.
The Seiko Rotocall Reissue is a thoughtful and well-executed tribute to a true icon. It delivers a compelling story, unique functionality, and a robust build that should appeal to collectors and enthusiasts seeking a watch with genuine heritage and character.
