Grand Seiko Adds Two Hand-Wound Timepieces to Heritage Collection

In 2022, we have seen a strong trend toward more classically-proportioned timepieces in the high-end sector. The latest example is two references joining Grand Seiko’s sought-after Heritage Collection, which is inspired by the Japanese watchmaker’s first releases in the 1960s.

The new references SBGW291 and SBGW293 are three-hand executions with a modest diameter of 36.5mm. As is de rigueur at Grand Seiko, they are pressure-resistant to 10 bars and operate at a high rate of precision.

Both of the new watches are distinguished by fine attributes that revisit the original 44GS design introduced in 1967. The design elements maintained by Grand Seiko include a flat sunray brushed dial, faceted and applied hour markers, Zaratsu-polished hands, and a complimentary Zaratsu polished steel case.

The Zaratsu finishing technique allows for the models to have contrasting textures along the surface of the case that creates a subtle play of light.

Both watches are driven by the manual winding Caliber 9S64 equipped with an anti-magnetic and shock-resistant balance spring. The mechanism also provides a stop-seconds function. Grand Seiko boasts high standards of accuracy with the regulation of +5/-3 seconds per day and a power reserve of 72 hours.

The new Grand Seiko Heritage Collection references SBGW291 and SBGW293 retail for $5,200 each.

  1. Nice watches.
    Grand Seiko’s website says the 9S64’s accuracy in normal usage is -1 to +10 seconds/day.
    The -3 to +5 s/d figure you quote is for the uncased movements during accuracy testing. It is misleading to refer to that and not the -1 to +10 s/d figure, since any GS warranty claim has to be based on the -1 to +10 s/d value.
