Next up on our “Anatomy of Grand Seiko”: Hands and hour markers. Let’s start with the style: Grand Seiko hands are traditionally flat, tapered dauphine, while the markers are faceted and tall. To make the hands, Seiko first shapes them three-dimensionally and then high polishes each facet with a diamond cutter. In the case of the SBGJ019, four of the five facets of the hour and minute hands are mirror polished, with the top surface brushed to an incredible level of detail. The seconds hand is pressed, but, unlike ordinary processes that yield a flat hand, the Grand Seiko method produces a fully three-dimensional hand, which is then buffed for polishing and plated (for many GS models, the seconds hands also go through a manually controlled heating process to achieve an incredible indigo blue color). Turning to the markers, each one is diamond-cut and polished to up to 9 surfaces (it takes up to three weeks to produce them). Each marker has two legs used to fix them to the dial, which is then finished with an adhesive agent, a similar process used for professional divers and other tool watches, where high impact is expected. Specifically for the SBGJ019, the GMT hand stands out further due to the tasty addition of a dash of red to its tip. Also, for this watch, the minute and seconds hands are tenderly curved downward by hand, bringing them closer to the dial to compensate for the added height by the extra GMT hand, sharply enhancing legibility. The end result are hands that feel solid—powerful, really—with enough polish to catch even the slightest glimmer of light for outstanding legibility. @thewatcherist
