Seiko 145th Anniversary Limited Editions

The year 2026 marks a monumental milestone for Seiko as the brand celebrates its 145th anniversary, a journey that began in 1881 when Kintaro Hattori opened a shop in Tokyo’s Ginza district to sell and repair timepieces. Hattori’s founding vision was not merely to retail commercial goods but to push the Japanese watchmaking industry forward, eventually leading to the establishment of the Seikosha factory in 1892. To honor this nearly century-and-a-half legacy, Seiko has unveiled a quartet of limited-edition timepieces spanning its most prominent collections: King Seiko, Prospex, Presage, and Astron. These four watches share a unifying aesthetic theme characterized by intricate dial patterns and luxurious gold-colored accents, a direct homage to the custom engravings Hattori commissioned for the imported pocket watches sold during his company’s nascent years.

The collection serves as a tangible timeline of the brand’s evolution, bridging the gap between the decorative artistry of the late 19th century and the high-tech precision of the 21st. By selecting specific models from the King Seiko, Prospex, Presage, and Astron families, Seiko ensures that every facet of its identity—from mechanical mastery and sports timing to traditional craftsmanship and electronic innovation—is represented. The recurring motif of gold set against diverse case materials and dial textures creates a cohesive narrative of prosperity and success, symbolizing the enduring relevance of Hattori’s "Always one step ahead of the rest" philosophy.



Leading the commemorative lineup is the King Seiko SJE121, a model that perfectly encapsulates the sophisticated "KS" aesthetic that rivaled the best of Swiss watchmaking in the 1960s. Based on the recently revived KS1969 chassis, this limited edition of 800 pieces features a slim, tonneau-shaped case that sits low and comfortably on the wrist, thanks to a thickness of just 9.9mm. The stainless steel case exhibits the sharp, angular geometry associated with the brand’s "Grammar of Design," featuring mirror-polished surfaces that contrast brilliantly with hairline-brushed sections. This play of light is further enhanced by the multi-row bracelet, which drapes fluidly like vintage beads-of-rice bracelets but with a modern, solid construction that conveys durability.

The dial of the SJE121 is where the anniversary tribute becomes most apparent. It features a mesmerizing radial pattern, reminiscent of the traditional Japanese "Nanako" or fish-roe motif, which adds a tactile visual density to the face of the watch. The surface is finished in a grey gradation that is lighter at the center and fades to a deep, smoky charcoal at the periphery. This vignetting effect draws the eye inward, where the gold-colored hands and applied indices pop with exceptional clarity. The seconds hand, a needle-thin streak of gold, glides smoothly over the textured surface, driven by the Caliber 6L35.

Inside the SJE121 beats the slimline Caliber 6L35, a movement developed specifically to allow for thinner case profiles without sacrificing performance. Operating at a frequency of 28,800 vibrations per hour (4Hz), the movement offers a power reserve of approximately 45 hours. The use of this caliber is a deliberate choice to maintain the svelte proportions of the original 1969 King Seiko models while providing modern magnetic resistance of 4,800 A/m. The watch is protected by a box-shaped sapphire crystal with anti-reflective coating, ensuring that the intricate dial texture remains visible from acute angles.



Representing Seiko’s rich history in sports timing is the Prospex Speedtimer SRQ059, a limited edition of 700 pieces that channels the spirit of the 1964 and 1969 chronographs. The watch features a substantial 42mm stainless steel case with a super-hard coating, ensuring that the polished surfaces remain pristine even with daily wear. The case silhouette flows seamlessly into the bracelet, echoing the integrated lines of 1970s sports watches, while the dual-curved sapphire crystal adds a vintage distortion-free clarity. The pushers are shaped like traditional pump pushers, offering a satisfying tactile response when engaging the stopwatch functions.

The dial of the SRQ059 is a study in texture and legibility. It utilizes a white background adorned with a complex woven pattern, another nod to the decorative engravings found on Kintaro Hattori’s early inventory. This white canvas serves as the perfect backdrop for the gold-colored hands and hour markers, which provide a luxurious contrast often absent in strict tool watches. The sub-dials are recessed, adding depth to the display, with the 30-minute counter at 9 o'clock and the 12-hour counter at 6 o'clock arranged in a classic bi-compax layout that prioritizes readability.

Under the hood, the Speedtimer is powered by the Caliber 8R48, Seiko’s most advanced mechanical chronograph movement. This engine is defined by its use of a vertical clutch and column wheel, a combination that ensures the chronograph seconds hand starts instantly without the "jump" often seen in cam-actuated mechanisms. The vertical clutch also reduces wear on the components during prolonged operation. Furthermore, the escapement is manufactured using Micro-Electro-Mechanical Systems (MEMS) technology, which allows for lighter, more precise parts that improve energy transfer and consistency.



Perhaps the most historically evocative member of the quartet is the Presage SPB538, a limited edition of 1,450 pieces that looks back to Seiko’s very first pocket watch, the "Timekeeper" of 1895. This timepiece is visibly distinct from its peers, featuring a petite 35mm stainless steel case that is completely gold-colored, mimicking the precious metal cases of the late 19th century. The case design incorporates unique, movable wire-style lugs, a feature that recalls the transitional era when pocket watches were first being converted for wrist wear. The crown is a prominent onion shape, deeply knurled to facilitate winding, further cementing the antique aesthetic.

The dial of the SPB538 is a masterpiece of traditional craftsmanship, executed in pure white enamel. Unlike lacquered dials, fired enamel possesses a unique, glossy sheen and a soft, warm depth that does not fade over time. The production of these dials is notoriously difficult, requiring the oversight of master craftsman Mitsuru Yokosawa to ensure that the glaze is applied evenly and fired without cracking. The Roman numeral hour markers are painted in a slender, classical font, and the "XII" is highlighted in red—a signature touch seen on the seminal Seiko Laurel of 1913.

Despite its vintage exterior, the SPB538 is a thoroughly modern watch in terms of specifications. It is powered by the Caliber 6R51, a robust automatic movement that delivers an impressive 72-hour power reserve, allowing the wearer to set the watch down for a weekend and pick it up on Monday without needing to reset it. The watch is fitted with a pull-through leather strap made from leather sourced from LWG-certified tanneries, ensuring sustainability aligns with luxury. The strap design, which passes underneath the case, adds a bit of visual bulk, making the 35mm diameter wear with more presence than the dimensions suggest.



Completing the collection is the Astron SSH186, a futuristic counterpoint to the historical themes of the other three models. Limited to 1,450 pieces, this watch celebrates the revolution Seiko started in 1969 with the Quartz Astron and revived in 2012 with the GPS Solar. The 44.1mm case is crafted from titanium and finished with a black super-hard coating, giving it a stealthy, aggressive profile that is surprisingly lightweight. The angular, faceted lugs and integrated bracelet design communicate a sense of advanced engineering and aerodynamic performance.

The "gold" theme is integrated into the Astron with a high-tech twist. The bezel features a sapphire crystal insert with gold-colored accents that appear to float beneath the surface, adding a three-dimensional quality to the watch's face. The dial itself is a complex multi-layered affair, with sub-dials for the dual-time and chronograph functions arranged in a logical hierarchy. A subtle but meaningful detail is found on the UTC scale, where the numbers 1, 4, and 5 are highlighted in gold, serving as a discrete code for the 145th anniversary.



Technologically, the SSH186 is the most advanced of the group, powered by the Caliber 5X83. This movement automatically connects to the GPS network up to twice a day to ensure atomic-level precision anywhere on Earth. It features high-speed time zone adjustment, a perpetual calendar correct to the year 2100, and a dual-time function that allows travelers to easily track their home time alongside local time. The solar-charging capability means the watch never requires a battery change, deriving all necessary energy from light sources.
