Seiko announced 7,000 pieces worldwide of each model. They launched in Japan on September 5, 2025; the corresponding regional references are SRPL99 and SSK047, while the Japanese release identifies them as SBSA319 and SBSC023.
Two watches, two Pepsi design eras
The collaboration draws on two different Pepsi identities rather than applying one color scheme to two versions of the same watch. Seiko’s regional collaboration page describes the first Seiko 5 Sports × Pepsi pair and its design details.

SRPL99 / SBSA319: 1990s-inspired, 38 mm automatic
This model pairs a white-silver dial with white indexes framed in blue, drawing on the blue, white and red palette of Pepsi’s 1990s logo. The logo-inspired dial detail sits at 6 o’clock. Its case measures 38.0 mm across and 12.1 mm thick. Inside is Seiko Caliber 4R36, an automatic movement that can also be wound by hand.
SSK047 / SBSC023: black-and-blue GMT
The larger watch takes its black-and-blue palette from Pepsi’s updated identity, with design input credited to PepsiCo Design & Innovation. Seiko’s Japanese launch specification gives its case diameter as 42.5 mm and thickness as 13.6 mm; the regional collaboration page rounds the diameter to 42 mm. It is fitted with a silicone strap embossed with “PEPSI” on the 12 o’clock side and marked with a Pepsi logo near the 6 o’clock end.
