Seiko Watches 5 Rotocall SMGG19

In 1982, NASA astronauts strapped on a Seiko digital watch unlike anything else on the market — not because it was issued to them, but because they chose it. The original A829 "Rotocall" flew on shuttle missions with icons like Anna Fisher and Ulf Merbold, prized for a rotating bezel that let wearers cycle through functions without fumbling for buttons, even in bulky gloves or zero gravity. Now, Lexor Miami is proud to offer the modern reissue that brings that legend back to the wrist: the Seiko Rotocall SMGG19.

Housed in a compact 37mm stainless steel case with a wearable 10.6mm profile and 43.5mm lug-to-lug fit, this digital watch balances retro charm with everyday comfort. The signature octagonal rotary switch bezel — finished here in a striking red and black colorway over an anthracite dial — remains the star of the show, letting you rotate between time, chronograph, alarm, and dual-time modes exactly as astronauts once did.

Powered by Seiko's in-house Caliber A824 quartz movement, the Rotocall delivers reliable ±20-seconds-per-month accuracy, a chronograph capable of measuring up to 100 hours in 1/100-second increments, a single-time alarm, dual-time function for tracking a second city, and a battery life warning function that signals when it's time for a change — with roughly three years between battery swaps. A durable Hardlex crystal and screw case back protect the movement, while 100 meters of water resistance means this watch is ready for daily wear, travel, and unexpected weather without hesitation.

The five-row stainless steel bracelet secures with a three-fold clasp and push-button release for quick, secure adjustments, and Seiko includes a 20mm NATO-style strap for effortless style changes.

More than a watch, the Rotocall SMGG19 is a piece of space-age design history brought current — a collectible for Seiko enthusiasts and a genuine conversation starter for anyone who appreciates engineering with a story.
