| The Seiko SBPY181, SBPY183, SBPY185, and SBPY187. |
The art of timekeeping finds a fresh expression as Seiko's newly unveiled S Series chronographs marry rugged utility with sophisticated Japanese design, proving that advanced functionality can be elegantly accessible.
Seiko has officially unveiled a significant expansion of its popular Selection S Series, introducing four new chronograph references that blend practical durability with refined aesthetics. The new models—SBPY181 (brown dial), SBPY183 (blue dial), SBPY185 (black dial), and the standout SBPY187 (full black hard coating)—represent a thoughtful technical refresh aimed at the discerning entry-to-mid-range collector.
Building on the successful foundation of previous S Series watches, these 2026 releases are not merely new dial colors but a considered upgrade in material specifications. Each watch shares a versatile and wearable stainless steel case measuring 42.2 mm in diameter, 12.2 mm thick, with a 48.3 mm lug-to-lug distance, making it suitable for a wide range of wrist sizes.
The launch signals Seiko's continued commitment to offering high-value, feature-packed timepieces that bridge the gap between everyday reliability and technical prowess. With a release date set for March 26, 2026, these watches are poised to become new favorites for those seeking a dependable, solar-powered chronograph from a trusted horological house.
01 The New Faces of the S Series
The four new references each present a distinct character. The SBPY181 features a warm brown dial paired with a black bezel, evoking a classic, earthy tool-watch aesthetic. The SBPY183 offers a vibrant blue dial for a more dynamic and modern look. The SBPY185 presents a monochromatic black-on-black scheme with its black dial and bezel.
Crowning the series is the SBPY187, distinguished by its unified all-black appearance. This model features a black hard coating over the entire stainless steel case and bracelet, providing enhanced resistance to surface scratches and a stealthy, tactical finish that sets it apart as the most premium variant of the quartet.
02 Core Engineering: Solar Heart, Sapphire Shield
At the core of each timepiece is the Seiko V175 solar-quartz caliber. This robust movement eliminates battery changes, converting light into power that offers a six-month power reserve from a full charge while maintaining an accuracy of ±15 seconds per month.
The movement drives a fully functional 60-minute chronograph with precise 1/5-second increments, a practical 24-hour sub-dial, and a date display at 4:30. A major upgrade for the series is the use of a sapphire crystal with a "super clear" anti-reflective coating. This feature, often reserved for Seiko's higher-tier Prospex line, significantly improves visibility in all lighting conditions.
03 Built for the Real World
Beyond telling time, these chronographs are built to be reliable companions. Each model is rated for JIS Type 1 antimagnetic resistance, protecting the movement from daily magnetic exposure. For low-light legibility, Seiko employs its proprietary LumiBrite on the hands and indexes, ensuring the dial remains readable after sunset.
The bracelets are designed for secure and comfortable daily wear, with the SBPY187's hard-coated version offering extra durability. While mechanically identical to their predecessor, the SBPY167, these 2026 models earn their place through updated aesthetics and material enhancements that elevate the entire series.

04 Positioning and Availability
This expansion represents a strategic elevation of the S Series catalog. By incorporating sapphire crystals and advanced coatings typically found in more expensive collections, Seiko positions these chronographs firmly in the competitive entry-to-mid-range segment.
While official pricing is yet to be disclosed at the time of writing, the confirmed release date is March 26, 2026. The updates suggest these models will offer a compelling value proposition, providing Prospex-level specifications in a more accessible package, likely with improved availability for the new season.

Frequently Asked Questions
What is new about the 2026 Seiko S Series compared to the older model?
The primary upgrades are material-based. The new models (SBPY181, SBPY183, SBPY185, SBPY187) feature a sapphire crystal with an anti-reflective coating, a component typically used in Seiko's more expensive Prospex line. This offers better scratch resistance and clarity than the mineral crystal often used in earlier entries. The new dial designs and the special hard coating on the SBPY187 model also set this release apart.
How does the solar movement work, and what is its advantage?
The Seiko V175 caliber is a solar quartz movement. It has a solar cell beneath the dial that converts any light—sunlight or indoor lighting—into electrical energy to recharge the battery. The main advantage is convenience and longevity; you never need to replace the battery as long as the watch is exposed to light occasionally, and a full charge provides about six months of operation.
Is the Seiko SBPY187 worth the premium over the other models?
The SBPY187 commands a premium for its full black hard coating applied to the stainless steel case and bracelet. This coating provides increased resistance to scratches and scuffs on the surface, helping the watch maintain its new appearance longer. If you prefer a stealthy, tactical look and value this extra durability, the SBPY187 is the definitive choice. If not, the other models offer identical technical specs in different colorways.
Where can I purchase the new Seiko Selection chronographs?
The new S Series chronographs will be available starting March 26, 2026. At launch, they will be sold through Seiko's authorized retailers, which include select jewelry stores, watch specialists, and major department stores. While not yet available, reputable online platforms like Amazon may also carry them following the official release.
