■ Philosophy of S Series
Seiko Selection S Series is a collection that focuses on timeless design. SBPY183 is a new product for 2026 that embodies this philosophy, combining a standard design with stylish color accents. It is positioned as a sporty chronograph model that appeals to a wide range of age groups.
Based on the conventional SBPY167 series, it adopts a new dial texture and sapphire glass. It is located in the entry to mid-range segment and has the characteristic of being a product that combines practicality and quality.
■ The charm of the navy blue dial
The biggest feature of SBPY183 is its elegant navy blue dial. The muted colors blend seamlessly into both business and casual settings. Among the sibling models released at the same time: brown (SBPY181), black (SBPY185), and all black (SBPY187), it gives the most formal impression.
The dial features diamond-cut indexes that reflect light to improve visibility. It features a functional layout with a date display at 4:30, a 24-hour subdial at 3 o'clock, a small seconds at 9 o'clock, and a 60-minute counter at 6 o'clock.
■ The power of V175 solar movement
Equipped with Seiko's solar movement V175, it can run for about 6 months on a full charge. It can be charged using sunlight or indoor light, so it is convenient and does not require regular battery replacement. Its high accuracy, with an average monthly difference of ±15 seconds, makes it reliable for daily use.
The chronograph function can measure up to 60 minutes in 1/5 second increments. The overcharging prevention function keeps the battery in optimal condition. It also has a tachymeter function, so it can also be used to measure speed. It has the characteristic of being sporty and practical.
■ Luxurious sapphire glass
The windshield is made of sapphire glass and has an anti-reflective coating on the inside. It suppresses light reflection and improves the visibility of the dial, and it is scratch resistant and maintains its beautiful shine for a long time. This is a special tailoring that uses the high-class specifications normally used in the Prospex line for the entry model.
Sapphire glass has a hardness that is second only to diamond, greatly reducing scratches caused by daily use. You can feel safe knowing that your hair will remain beautiful for a long time. The high quality of the material is a big attraction of this model.
■ Case design with steps
By adding steps to the case lugs, we create a sharp impression that emphasizes light and shadow. The three-dimensional form gives off a solid presence on your wrist. The case size is approximately 48 x 42 x 12 mm, which is a standard size that is easy to handle by modern standards.
The stainless steel case is intricately crafted with a combination of textures and mirror finishes. The contrast between the matte texture and high gloss has the effect of enhancing the texture and sense of luxury. The moderate weight of approximately 130g maintains a perfect balance between wearability and presence.
■ Comfort of triple bracelet
The three-strand stainless steel bracelet is approximately 20mm wide and fits securely on your wrist. It is suitable for arm circumferences of up to 20cm, so it is the perfect size for many men. The pin-type adjustment method allows for fine size adjustments.
The bracelet also has a combination of texture and mirror finish, creating a sense of unity with the case. It's a finish unique to Seiko that combines comfort and beauty.
■ Practicality of 10 ATM water resistance
With 10 ATM water resistance (reinforced waterproof for daily life), you can wear it with confidence not only when washing your hands or on rainy days, but also when swimming or showering. The screw back design ensures waterproof performance. It is also anti-magnetic, so it can handle the magnetic fields you encounter in your daily life.
Useful in a wide range of situations, from daily use by businessmen to weekend activities. The tough and practical construction gives you the peace of mind that this watch can be used every day.
■ Lumibrite visibility
The hands and indexes are coated with Seiko's proprietary Lumibrite (luminescent paint) for excellent visibility even in the dark. There is a sense of security that it is easy to check the time even at night or in a dark place. The chronograph hands are also treated with luminescent material to improve readability.
The combination of diamond-cut indexes and Lumibrite ensures high visibility both day and night. It is characterized by a design that thoroughly pursues practicality.
■ Featured new models in 2026
One of the four new models added to the S Series as a new model released on March 26, 2026. Of the four colors available, SBPY181 (brown), SBPY183 (blue), SBPY185 (black), and SBPY187 (all black hard coating), it is positioned as the most suitable color for business situations.
As a technical upgrade from the previous model, sapphire glass and internal anti-reflective coating are used. It is a popular model for the 2026 season, achieving higher quality texture and visibility.
■ Practicality of tachymeter
The bezel is engraved with a tachymeter scale, which can be used to measure mileage and speed. By combining it with the chronograph function, you can easily calculate the speed per hour. This function is useful in situations such as motor sports, cycling, running, etc., where speed is measured.
While it is practical, it also has a visual effect that creates a sporty atmosphere. It has the characteristic of being a watch that allows you to enjoy the real pleasure of a chronograph watch.
