“Pepsi” is official now in Seiko 5 Sports: the collaboration comprises two limited-edition designs with Pepsi branding and Pepsi-can-inspired packaging. The compact SRPL99 (Japanese reference SBSA319) is a day/date watch; the larger SSK047 (Japanese reference SBSC023) is a GMT watch that can show two time zones. Seiko announced each design as a 7,000-piece worldwide edition, including 500 pieces allocated to Japan per reference.
Collectors have long used “Pepsi” informally for watches with red-and-blue bezels. The significance here is the official partnership and branding, not the invention of that nickname or the first watch ever described as Pepsi.

What “Pepsi” means in watch collecting
In watch culture, “Pepsi” usually means a watch with a blue-and-red bezel, particularly a GMT or dive-style design. The nickname is strongly associated with Rolex’s GMT-Master family, but collectors and retailers also use it informally for other watches with the same color language.
Seiko already had a well-known example: the Seiko 5 Sports SRPD53, a regular-production model with a blue-and-red bezel. Enthusiasts commonly call it a “Pepsi” Seiko, but it is not part of the Pepsi collaboration.

The new watches change the meaning from informal shorthand to official branding.

Their see-through case backs show Pepsi logo details, “LIMITED EDITION,” and an individual serial number.
The two-watch collection at a glance
| Design and regional references | Movement and function | Case | Strap or bracelet | Edition size |
|---|---|---|---|---|
| Compact: SRPL99 (international) / SBSA319 (Japan) | 4R36 automatic with manual winding; day/date | Stainless steel; 38.0mm diameter, 12.1mm thick | Stainless-steel bracelet | 7,000 worldwide; 500 allocated to Japan |
| GMT: SSK047 (international) / SBSC023 (Japan) | 4R34 automatic GMT with 24-hour hand; two time zones | Black-coated stainless steel; 42.5mm diameter, 13.6mm thick | Silicone strap | 7,000 worldwide; 500 allocated to Japan |
Seiko lists about 41 hours of power reserve, 24 jewels, and 21,600 vibrations per hour for both movements. Both watches have Hardlex crystals and 10-atmosphere water resistance. A rotating bezel and sports-watch styling do not make either a professional dive instrument.
Seiko SRPL99: the compact 1990s Pepsi watch
The SRPL99 is the more nostalgic model. Its 38.0mm stainless-steel case, silver-white dial, blue-edged white indices, and blue-and-red bezel create a compact, retro-leaning design.
Seiko describes the dial’s Pepsi logo typography as a reference to the brand’s 1990s identity. The watch uses the 4R36 automatic movement with manual winding and a day/date display. In Japan, this design is identified by reference SBSA319; it is not a third design.
SRPL99 specifications
- International reference: SRPL99
- Japanese reference: SBSA319
- Movement: Seiko Caliber 4R36 automatic with manual winding
- Functions: Hours, minutes, seconds, day/date
- Power reserve: About 41 hours
- Jewels: 24
- Vibrations: 21,600 per hour
- Case: Stainless steel; 38.0mm diameter and 12.1mm thick
- Crystal: Hardlex
- Water resistance: 10 atmospheres
- Bracelet: Stainless steel
The 4R36 is an everyday automatic movement with manual winding and a day/date display. The SRPL99’s appeal is its compact format, period-inspired graphics, and official Pepsi branding.
The Japanese-market reference: SBSA319
In Japan, the compact collaboration watch is identified as SBSA319. It corresponds to the international SRPL99, rather than representing a third watch in the collection. Seiko’s 2025 announcement allocated 500 pieces of this reference to Japan within its 7,000-piece worldwide edition.
Seiko SSK047: the Pepsi GMT
The SSK047 takes the collaboration in a more contemporary direction. It uses a black-dominant design with blue and red accents, a 24-hour bezel, and a silicone strap embossed with “PEPSI.” Its Japanese-market reference is SBSC023.
The SSK047 uses Seiko’s 4R34 automatic GMT calibre with manual winding. Its 24-hour hand and bezel allow the wearer to display a second time zone alongside the main time display.
SSK047 specifications
- International reference: SSK047
- Japanese reference: SBSC023
- Movement: Seiko Caliber 4R34 automatic with manual winding
- Function: GMT/24-hour hand for displaying two time zones
- Power reserve: About 41 hours
- Jewels: 24
- Vibrations: 21,600 per hour
- Case: Black-coated stainless steel; 42.5mm diameter and 13.6mm thick
- Crystal: Hardlex
- Water resistance: 10 atmospheres
- Strap: Silicone
The GMT function is the main practical difference from the SRPL99. The Pepsi-branded strap and black-dominant treatment give the SSK047 a more overtly contemporary sports-watch character.
SRPL99 versus SSK047: which one makes more sense?
| Choose the SRPL99 if you want… | Choose the SSK047 if you want… |
|---|---|
| A compact 38.0mm case | A larger 42.5mm case |
| A silver-white dial and 1990s-inspired Pepsi design | A black-dominant design with blue and red accents |
| A day/date watch with the 4R36 | A GMT watch with the 4R34 for two time zones |
| A stainless-steel bracelet | A silicone strap embossed with “PEPSI” |
| A retro-leaning look | A more contemporary GMT look |
The watches interpret the Pepsi identity through different Seiko 5 Sports formats. The SRPL99 is the compact day/date design; the SSK047 adds a GMT function and a black-dominant palette.
What the collaboration is—and is not
It is an official Seiko 5 Sports and Pepsi collaboration
The Pepsi name is not merely being applied by a retailer or enthusiast to a red-and-blue bezel. These limited editions have Pepsi branding on the watches and Pepsi-can-inspired packaging. Their see-through case backs include Pepsi logo details, “LIMITED EDITION,” and an individual serial number.
It is not a professional dive-watch release
Both watches have 10-atmosphere water resistance, but Seiko does not present them in the supplied launch material as professional dive instruments. A rotating bezel and sports-watch design alone do not establish professional diving suitability.

It is not a technical equivalent of a Rolex GMT-Master
The shared “Pepsi” term refers to color language and collector vocabulary, not equivalent construction, movement architecture, finishing, water resistance, or price. The comparison is cultural and visual, not a claim of equal technical specification or luxury positioning.
Where these watches fit in Seiko 5 Sports
Seiko traces the broader Seiko 5 family to the 1963 Sportsmatic 5 and says Seiko 5 Sports was established in 1968. The collection has historically emphasized automatic movements, durability, legibility, water resistance, and everyday practicality.
Seiko relaunched the modern Seiko 5 Sports line in 2019. Its appeal is mechanical sports-watch design and automatic movements at a more approachable level than the brand’s Prospex or luxury collections. The Pepsi collaboration adds collectible branding and limited-edition packaging while retaining familiar Seiko 5 Sports architecture.
The non-collaboration alternative: Seiko SRPD53
Readers who want the red-and-blue Seiko look without the collaboration branding can consider the regular Seiko 5 Sports SRPD53. Enthusiasts often call it a “Pepsi” because of its colors, but it is not one of the official Pepsi-branded collaboration editions.

Seiko announced the collaboration on August 5, 2025, with release scheduled for September 5, 2025. The two designs were announced as 7,000-piece worldwide editions each, with 500 pieces per reference allocated to Japan. These are release-era quantities, not a statement of present-day stock.
Seiko Watch Corporation’s August 2025 Japanese announcement listed suggested retail prices of ¥51,700 for SBSA319 and ¥73,700 for SBSC023. These are Japan-market launch prices, not current prices or estimates of fair value. The international references corresponding to those Japanese models are SRPL99 and SSK047.
Current stock, resale prices, seller quality, and warranty coverage are not established by the launch information. Verify the exact reference, seller, condition, warranty, and included packaging before buying. Limited-edition status alone does not show that a watch will appreciate or be difficult to find.
What to check before buying
- Confirm the reference. The compact design is SRPL99 internationally and SBSA319 in Japan. The GMT design is SSK047 internationally and SBSC023 in Japan.
- Do not confuse SRPD53 with the collaboration. Its blue-and-red bezel is familiar, but it does not carry the official Pepsi partnership branding.
- Choose the function you need. The SRPL99 uses the 4R36 with day/date; the SSK047 uses the 4R34 GMT to show two time zones.
- Compare the case and strap. The SRPL99 is 38.0mm with a steel bracelet; the SSK047 is 42.5mm with a silicone strap.
- Check the package contents. The Pepsi-can-inspired container and branded case-back details are part of the limited-edition presentation.
- Verify warranty and provenance. Check these details with the seller, especially for a secondary-market or cross-region purchase.
- Treat launch prices as historical references. Seiko’s quoted yen prices are Japan-market launch prices, not guarantees of current pricing.
Why this release matters
Seiko’s Pepsi watches are notable because they formalize a language collectors were already using. The red-and-blue bezel was familiar long before this collaboration, and enthusiasts already called watches such as the SRPD53 “Pepsi.” What is new is the official co-branded identity.
The two models apply that identity to different Seiko 5 Sports designs: a compact day/date watch and a larger GMT. Both retain the collection’s familiar automatic-watch character while adding Pepsi branding and special packaging.
FAQ
Are the Seiko SRPL99 and SSK047 the same watch?
No. The SRPL99 is the compact day/date design with a 4R36 movement and steel bracelet. The SSK047 is the larger GMT design with a 4R34 movement and silicone strap.
Is SBSA319 a third Pepsi collaboration model?
No. SBSA319 is the Japanese-market reference for the compact SRPL99 design. The GMT design’s Japanese reference is SBSC023.

They have 10-atmosphere water resistance, but the supplied launch information does not identify them as professional dive instruments. A rotating bezel alone does not make a watch a professional diver.
What is the difference between these watches and the Seiko SRPD53?
The SRPD53 is a regular Seiko 5 Sports model that enthusiasts commonly call a Pepsi because of its red-and-blue bezel. The SRPL99 and SSK047 are the official Seiko 5 Sports x Pepsi collaboration designs with Pepsi branding and special packaging.
Which Seiko 5 Sports x Pepsi model is smaller?
The SRPL99 is smaller at 38.0mm in diameter and 12.1mm thick. The SSK047 measures 42.5mm in diameter and 13.6mm thick.
Does the SSK047 show two time zones?
Yes. Its 4R34 GMT movement uses a 24-hour hand and bezel to display a second time zone alongside the main time display.

What are the Japanese references for the two designs?
The compact SRPL99 design is SBSA319 in Japan, and the GMT SSK047 design is SBSC023. They are regional references for the two designs, not additional watches.
The Bottom Line
The Seiko 5 Sports x Pepsi collection is notable less because red and blue are new to watches than because Seiko has made “Pepsi” official. The SRPL99 (SBSA319 in Japan) is the compact day/date choice; the SSK047 (SBSC023 in Japan) is the larger GMT. Each was announced as a 7,000-piece worldwide edition, with 500 allocated to Japan, and comes with Pepsi branding and special packaging.
