Grand Seiko Heritage 29mm Quartz ‘Diamond Snowflake’ Replica Watch

SBGE313
The Grand Seiko SBGE313 is a sporty GMT watch, limited to 450 pieces and available exclusively at the Ginza boutique. It features a 44mm stainless steel case, a purple grid dial, and a purple and white rotating bezel. It's powered by the 9R66 Spring Drive movement, equipped with a GMT function, date display, and power reserve indicator. It's water-resistant to 200 meters and comes with a matching stainless steel bracelet and a double-curved sapphire crystal. The caseback is engraved with "GINZA LIMITED EDITION" and the serial number.

While Grand Seiko often varies the color and texture of its dials, this "irregular tennis racket" grid pattern is completely new. It's a decidedly unique look.

SBGJ289 and SBGJ291: Wako Exclusives
According to Plus9Time, both the SBGJ289 and SBGJ291 are limited editions of 70 pieces and are also available exclusively at the Grand Seiko Ginza flagship store in Wako. Its stainless steel case measures 39.5 mm x 14.1 mm x 46.9 mm, the same as the SBGJ249. The understated, elegant lugs clearly indicate that both watches belong to the Elegance Collection.

The SBGJ289 features a turquoise textured dial and a white GMT hand. The SBGJ291 features a silver dial with a concentric sunburst pattern, a pattern popular in Swiss watchmaking a century ago. Inside, it's powered by the excellent, though no longer current, high-frequency 9S86 movement. It comes with both a bracelet and an alligator leather strap (turquoise for the SBGJ289 and white for the SBGJ291).
