Grand Seiko’Soko’ SBGA427 and SBGA429 watches expand the U.S. exclusive Four Seasons series
As a supplement to three quarters of the “Seasons” watch that was exclusively available in the United States last year, Grand Seiko has just launched two new Spring Drive watches with a fall theme. I’m a big fan of the SBGA413 “Spring” watch (I own) last year, and I’m happy to see Seiko remake these reproducible series, making a total of 24 pieces, because Japan divides the season into six each sekki. These two Soko special edition watches feature green color, inspired by the Arashiyama bamboo forest in Kyoto.
Both are made of a 39mm stainless steel case with a vertical brushed dial. SBGA427 has a light silver dial with dark green tones on the second hand and power reserve hands; SBGA429 has a dark “shadow” dial with light green tones on the hands. I’m sure I’m not the only one who remembers the Omega Seamaster Aqua Terra “Golf” version. This is another classic, simple time and date watch with vertical stripes and a green seconds hand.
Brand: Grand Seiko
Models: Soko Special Edition SBGA427 and SBGA429
Dimensions: 39mm wide and 12.5mm thick
Water resistance: 100 meters
Case material: steel
Crystal/Lens: Hyperbolic sapphire with AR coating

Compared with the smaller stainless steel case and dial, the titanium spring and summer models (also using the 9R65 Spring Drive movement) have fine workmanship, plus a steel bracelet and leather strap and matching green stitching. It is a clear value game. Zaratsu’s hands and hands are the same as those of other models, although you won’t get a double hand at 12 o’clock.
End of Autumn: Grand Seiko launches two American special edition Heritage series
Inspired by the late autumn, Japanese watchmaker Grand Seiko launched two new special edition timepieces in its Heritage collection. The special edition in the Great Seiko Soko USA is to commemorate Japan’s 24 continuation of the Sekk I Red Moon Calendar, marking the ever-changing season of nature, each timepiece-in its two exterior designs and sports technology-visit Japan and its “Natural and continuous” time flow.

Both models of the second hand and power reserve indicator are decorated with green, while the vertical dial has a subtle bamboo pole texture, reminiscent of Japan’s Kyoto forest, called Arashivama.
These 39mm clocks are combined to pay tribute to the natural and vivid green tones, and the “light” and “shadow” patterns on the silver dial model (reference number SBGA427) form a sharp contrast. The words on the gray dial (Ref. SBGA429) show the high level of Japanese craftsmanship that Seiko expects.
The green accent color on the second hand and power reserve indicator symbolizes the life of Arashiyama.
Visible on the watch’s open bottom cover is the Spring Drive 9R65 movement, which was hand-designed, adjusted and assembled by craftsmen from the Shinshu Watch Studio in Japan. The spring-driven movement is one of the most noteworthy innovations in the modern watchmaking industry and is known for its most advanced electromagnetic regulators, which can operate without an external power source.
The spring-driven movement with the latest electromagnetic regulator can work without external power supply.
Its only source of power is the mainspring, which drives a series of gears-the same gears in traditional mechanical watches-providing one second of accuracy per day, which is unmatched by replica watches perfect driven by mainsprings. The Spring Drive movement with a 72-hour power reserve rotates the second hand around the dial, further celebrating the “poetic journey”.
