Seiko 5 SNKK25J1 Ref. 7S26-02W0 - November 2020
Throughout the decades-long history of the Seiko 5, hundreds of different dials have been produced based on the same mechanical foundation. What sets the SNKK25J1 apart from the rest is not a complication, but a small yet highly impactful design touch applied to just one-quarter of the dial.

The serial number 0N5939 on the case back points to November. Meanwhile, the 7S26C movement revision visible through the transparent case back narrows down the production decade, placing this specific example in November 2020. The product tag confirms the model as SNKK25J1 and the case code as 7S26-02W0.
The red-and-gray graphic sector located between the 12 and 3 o'clock positions creates the initial impression of a measurement scale or an additional indicator. In reality, it is not linked to any mechanical function. Nevertheless, when combined with the red central seconds hand, it alters the rhythm of the entire dial, transforming the SNKK25 from a standard white-dialed Seiko 5 into something unique.
The stainless steel case, measuring approximately 38.5 mm in diameter with a 20 mm lug width, maintains the model's compact Seiko 5 proportions. The day-date window at 3 o'clock, the recessed crown near 4 o'clock, and the multi-link steel bracelet all uphold the series' familiar architecture.
Inside, the 7S26C is an automatic movement featuring 21 jewels and operating at a frequency of 21,600 vibrations per hour. It boasts a power reserve of approximately 41 hours. It lacks manual winding and hacking capabilities. The strength of the 7S26 family lies not in its complexity, but in its design—engineered to run continuously with minimal user intervention.
This watch is in NOS (New Old Stock) and complete set condition. It comes with its outer and inner boxes, warranty and instruction manuals, model tag, and the protective films still intact on the bracelet and clasp.
Final Thoughts
The SNKK25J1 perfectly illustrates why the Seiko 5 is able to adopt so many different identities. The movement is the same, and the basic case design is familiar; yet, a splash of color on just a small section of the dial is enough to transform the entire character of the watch.
