Seiko has long used milestone years as an opportunity to re‑examine its history, and its 145th anniversary is no exception. The brand unveiled a quartet of limited editions that pair modern mechanics with heritage‑inspired details. Leading the lineup is the King Seiko SJE121, a refined reinterpretation of the 1969 King Seiko 45KCM. Its 39.4 mm tonneau‑shaped stainless‑steel case measures just 9.9 mm thick, yet deep fluted case sides create a slimmer impression.

Inside beats the caliber 6L35, an automatic movement rated for a 45‑hour power reserve. The real star is the gray gradient dial, which features a textured pattern inspired by founder Kintaro Hattori’s engravings and gold‑colored hour markers, hands and date window. Limited to 800 pieces, it retails for $3,100.

For chronograph fans, the Prospex Speedtimer SRQ059 revisits Seiko’s 1960s racing heritage. A 42 mm stainless steel case and vintage‑style bracelet house a crisp white dial with radial texture and gold accents. Three sub‑dials — small seconds, 30‑minute and 12‑hour counters — sit neatly within the layout, while black accents on the hands aid legibility. Power comes from the column‑wheel 8R48 automatic chronograph movement with a 45‑hour reserve. Seiko will produce 700 pieces of this model at $2,500 each.

Classical elegance appears in the Presage SPB538, part of the Craftsmanship series. The 35 mm gold‑plated stainless‑steel case references a vintage Seiko Timekeeper pocket watch and features articulating lugs and an onion crown. A pure white enamel dial with black Roman numerals and gold hands sits beneath a box‑shaped crystal. Beneath, the 6R51 automatic movement provides a 72‑hour power reserve. A pull‑through leather strap from a certified sustainable tannery completes the look. Limited to 1,450 pieces, it’s priced at $1,9000.

Finally, the Astron SSH186 demonstrates Seiko’s future‑facing side. The 44.1 × 14.4 mm black titanium case and bracelet feature gold accents and a matching sapphire bezel. Inside, the 5X83 GPS Solar chronograph movement syncs with satellites to automatically adjust time zones and includes a perpetual calendar accurate until 2100. Only 1,450 units will be made, each priced at $3,300.

Together, the collection shows Seiko’s ability to honor its past while embracing cutting‑edge technology.
