Seiko 5 Sports SKX Redux "7002" automatic yellow dial rubber strap 42,5 mm

Heritage & evolution of an icon

Before the legendary SKX of the 1990s, there was the Seiko 7002. Produced between 1988 and 1996, this robust diver left its mark on a generation with its functional design and strongly luminescent rectangular markers. It was later replaced by the SKX, which went on to become one of the most iconic and accessible automatic sports watches on the market.

In 2019, Seiko revived the SKX spirit within the 5 Sports collection, retaining the emblematic asymmetrical case architecture with a crown positioned at 4 o’clock. In 2025, the brand goes further with a refined aesthetic evolution: a bezel fitted with a glossy Hardlex glass insert, a slightly widened dial opening, and a redesigned index layout directly inspired by the 7002’s visual codes.

This new-generation SKX Series does not alter the philosophy of the model—a robust, versatile and accessible automatic watch—but subtly refines its lines, offering a more contemporary and elevated interpretation of a cult archival design.

A modernized SKX architecture

The new Seiko 5 Sports SKX Series retains the architecture that made the model successful: a 42.5 mm stainless steel case, a compact 46 mm lug-to-lug length and a thickness of 13.9 mm, ensuring a confident wrist presence while remaining comfortable to wear.

The emblematic asymmetrical silhouette, directly inherited from the SKX, integrates a crown positioned at 4 o’clock to enhance ergonomics and preserve the flow of the case lines. Water-resistant to 100 meters, the watch positions itself as a versatile sports model, suitable for daily wear as well as light aquatic activities.

The most notable evolution lies in the unidirectional bezel. Now equipped with a glossy Hardlex glass insert, it offers increased visual depth and a more contemporary play of light. The 60-minute scale is printed beneath the glass, creating a sharper and more refined overall effect.

The dial adopts a new rectangular index design inspired by the Seiko 7002, with a reinforced double marker at 12 o’clock for enhanced legibility. The hands have been redesigned in respect of the original model while benefiting from more precise and refined finishing. The entire display is treated with LumiBrite to ensure optimal readability in low-light conditions.

SRPL87: 1980s energy in a contemporary expression

With its vibrant yellow dial, the Seiko 5 Sports SRPL87 injects a bold dose of personality into the SKX universe. This luminous shade immediately recalls the aesthetic of late-1980s and early-1990s Seiko divers, while embracing a distinctly modern interpretation.

Paired with a black bezel featuring a glossy glass insert, the yellow dial creates a strong and dynamic contrast. The applied rectangular indexes and redesigned hands benefit from improved finishing, while LumiBrite ensures optimal legibility both in daylight and low-light conditions.

The SRPL87 is fitted with a black silicone strap, a nod to original sport-oriented configurations. Flexible and comfortable, it enhances the model’s summery, relaxed character while maintaining genuine sporting credibility.

More expressive than its steel-bracelet counterparts, the SRPL87 is aimed at those seeking an automatic watch with a confident identity—one that adds real personality to the wrist without compromising the technical DNA of the collection.

The 4R36 calibre: Seiko’s signature mechanical reliability

At the heart of this new Seiko 5 Sports SKX Series beats the in-house 4R36 calibre, an automatic movement developed and assembled internally by Seiko.

Operating at a frequency of 21,600 vibrations per hour (3 Hz), it features 24 jewels and delivers a power reserve of approximately 41 hours—perfectly suited for daily use. Robust and proven, it has long served as Seiko’s benchmark entry-level mechanical movement.

The 4R36 offers:

• Automatic winding via rotor
• Manual winding capability
• Stop-seconds (hacking) function for precise time-setting
• Day-date display at 3 o’clock

Seiko states a theoretical accuracy range of +45 to -35 seconds per day, consistent with its accessible and pragmatic positioning.

Visible through the transparent caseback, the movement does not seek decorative extravagance; instead, it prioritizes reliability, durability and ease of maintenance. A straightforward, efficient mechanism designed to stand the test of time.

The Seiko 5 spirit: five pillars since 1963

Since its launch in 1963 with the Sportimatic 5, the Seiko 5 collection has been guided by a simple philosophy: to offer a reliable, robust and accessible automatic watch without compromising on essentials.

The number “5” refers to the five defining characteristics present in every model of the line—and fully embodied in this new SKX Series generation:

1. An in-house automatic movement
2. A day-date display, the collection’s historic signature
3. Water resistance suited to active daily wear
4. A recessed crown at 4 o’clock for comfort and protection
5. A durable case and bracelet built for everyday longevity

With this 2025 evolution, Seiko once again demonstrates its ability to evolve its icons without betraying their DNA: a sporty, versatile and mechanically accessible watch, faithful to the original Seiko 5 spirit.
