Model: Grand Seiko “Elegance” SBGK007 / 9S63-00A0
Year: December 2019
Features:
The Harmony. The dial does the impossible - it balances the power reserve indicator. It’s not something I’ve ever been troubled by, but judging by comments online, a lot of people are unhappy with the asymmetry its existence causes. The clever addition of the small seconds subdial not only brings harmony do the dial, but it has the added benefit of giving the watch a distinctly vintage look.
The Clean Look. Of course, it’s possible to put the power reserve indicator on the back, as seen on the SBGY007 Omiwatari, but I’d suggest the empty void this creates has to be satiated with something - which is why SPRING DRIVE is emblazoned across its dial. In contrast, the SBGK007 is wonderfully devoid of noisy text. Despite the inclusion of the PRI and small seconds, I would argue it feels quieter and more subdued than the Omiwatari’s “simpler” dial.
The Dial. Speaking of the dial - white, silver, or yellow? It depends who you ask. Grand Seiko calls it “clean white”, which is interesting, because I don’t think either word is quite right. It’s closer to ivory or soft champagne - almost as if a white 1960s dial has aged gracefully. And “clean”? Not quite. Fine striations radiate from the centre, creating a gentle sunburst texture.
The Profile. As you may already know, converting central seconds into small seconds allows the watch to shave ~1.0mm off its height, but Grand Seiko didn’t stop there on its quest to ensure the watch slips under any cuff. The dial itself curves downwards at the edges, allowing the crystal to slope more steeply and meet the case edge more quickly. It’s a subtle effect, but the results become obvious if you study the inward angle of the lugs - their shape is clearly informed by the slender profile.
The Accuracy. This is unmistakably a dress watch, confirmed by the use of a manual-wind movement. The mechanical 9S63 beats at 28,800bph, features 33 jewels, and is tested beyond Switzerland’s COSC standard. While COSC require testing in five positions, at three temperatures, with an accuracy of -4/+6 seconds per day, all over 15 days, Grand Seiko has opted for a more rigorous method. Six positions. Three temperatures. -3/+5 seconds accuracy. 17 days. This thing is accurate. +/- 0 seconds per day on my timegrapher.
The Caseback. The movement is proudly displayed through an exhibition caseback. Geneva stripes decorate the bridges, and a barely visible Grand Seiko lion is etched into the glass. So subtle, in fact, that I couldn’t photograph it - but I promise it’s there for anyone willing to hunt it at the right angle in the right light.
