3 Year Warranty

Re-introducing Seiko’s iconic 1980s digital model, the SMGG19P1 revives the legendary “Rotocall” with modern build quality, bold red & black accents, stainless steel bracelet and full digital multifunctions. A retro-tool watch with contemporary reliability.

Design & Heritage

• The SMGG21P1 draws directly from the original 1982 Seiko “Rotocall” digital watch — famed for its octagonal rotary switch bezel and use by astronauts.

• Instead of traditional push buttons, the bezel itself is rotated to switch modes — giving the watch a tactile, mechanical feel and distinctive character.

• The striking combination of a blue & grey theme (model SMGG21P1) gives a bold, sporty aesthetic — for those wanting something out of the ordinary.
