The details
Full description
This sports timepiece demonstrates the essential qualities of Grand Seiko: accuracy, beauty, legibility, durability and ease of use.
The case is a classic slim design for a comfortable fit, its surface features a finely brushed hairline finish Ð a skill perfected by Grand Seiko craftspeople Ð contrasting the signature Zaratsu mirrored polishing.
This watch is powered by the in-house 9F86 Quartz calibre adjusted to an accuracy of -/+ 10 seconds per year.
Every quartz crystal has different performance characteristics, but only the most accurate are picked for Grand Seiko 9F movements. Grown in-house, aged and rigorously tested over a 3 month period, this ensures only the best quartz oscillators are crafted into each timepiece.
Calibre 9F delivers long-lasting high performance through innovation: the instant Date Change Mechanism swiftly changes the date display; the torque is comparable to a mechanical movement allowing easy-to-read wider and longer hands; the Second hand precision achieves positional accuracy on the dial against the markers; and the sealed structure means high retention of lubricating oils.
The screw-lock crown means the watch maintains excellent airtightness with a 20 bar water-resistance, as well as durability. Its powerful hands and grooved, prominent markers with LumiBrite ensure high legibility, whilst the contrast created by the upper and lower two-toned dial rings indicates if the GMT hand time is day or night.
Grand Seiko: beautifully precise Japanese watchmaking, handcrafted by Takumi artisans.
