I’ll start with what I recognize is an intense assertion: the Grand Seiko Spring Drive Chronograph SBGC001, completely, all things considered out of the crate, is actually the package of plan, movement, usefulness, innovation, exactness, and worth that at least one significant Swiss brands ought to at any rate be attempting to offer.

You see, even before I typed a single expression of it I knew: this audit of the Grand Seiko Spring Drive Chronograph SBGC001 would have been the most testing watch survey I’ve written to date. The explanation is deceivingly straightforward, however: I for one believe the SBGC001 to be among the most perfect watches out there, accessible at any value right now available. I have given that assertion a great deal of thought all through several weeks of cautious thought and incalculable comparisons to elective brands and models. Anyway, where’s the test in making this survey? All things considered, it is in passing on all that delivers this watch, as far as I might be concerned, all the watch one might require. Here we go.


I’ll address everything from wearability through movement usefulness right to a part committed to the pushers and crown (yes!), yet permit me to make a couple of strides back and start with a more extensive glance at the section of extravagance chronographs to decide how the Grand Seiko Spring Drive Chronograph SBGC001 fits in it (or doesn’t).

It has happened a larger number of times than I would mind to consider that some significant Swiss brands debut another ish extravagance chronograph – nowadays essentially only with a five-figure sticker price – aficionados of said brands (or simply the portion) legitimately shout out something like “there’s nothing new about this watch!” or “a new bezel material/shading plan doesn’t make this a new watch!

Let’s be reasonable. Noteworthy endeavors have been made by Omega’s Master Chronometer types, with a couple of chronographs presently beginning to highlight their enemy of attractive innovation ( like this Moonwatch ), however said examples retail for around $11,000. At a similar time, Rolex’s (to be honest, great) 4130 chronograph type of the Daytona remains generally unaltered since its introduction in 2000, aside from it finishing more stringent in-house assessments. We could specify the Heuer-01, however separated from it being accessible at moderately competitive value focuses, the movement itself has no new mechanical highlights – it is “just” a pleasant chronograph. The equivalent goes for basically any remaining “new chronographs”: have there been any genuinely new in-house chronographs delivered over the most recent couple of years? Indeed, from Alpina through Cartier to Christopher Ward, yet none have offered any real headways separated from asserting an assembling status.


The point I need to make is that it was not the Swiss, but rather the Japanese who had the inspiration, assets, and expertise to deliver something (in truth, currently the only thing) that I for one consider a genuine headway for mass-created mechanical chronograph movements, such a jump forward that infers we have indeed entered the 21st century.

The History & Functionality Of Spring Drive

If you haven’t as of now, may I now propose that you read my comprehensive article we distributed yesterday on the usefulness and history of Spring Drive , where we talk about its intricate details including the quick innovative headways it took Seiko to, after exactly thirty years of advancement, carry Spring Drive to the worldwide market. Understanding what Spring Drive is and how it functions is fundamental to seeing how the Grand Seiko Spring Drive Chronograph SBGC001 and its brethren vary so unfathomably from some other extravagance chronograph available to be purchased today.

In a nutshell, Spring Drive is an interesting combination of a mechanical and a quartz-directed movement. Spring Drive comprises (is driven by) an injury mainspring and contains a stuff train much the same as a normal mechanical watch. Notwithstanding, toward the finish of the stuff train, the last wheel turns ceaselessly one way rather than the to and fro movement of customary wheels. As this supposed “rotor” turns, it charges a little loop to make a strikingly low-power electronic charge that thus controls an incorporated circuit and a quartz oscillator. These two sections work pair with an occasionally applied electromagnetic brake to manage the pivoting speed (and subsequently the timekeeping precision) of the rotor. No battery of any sort is included; it is totally started up by a mainspring that you can renew through the crown or the programmed winding function.

More on the movement in its assigned chapter.

A Very Brief History Of The SBGC001

In 2007, it was the SBGC001, SBGC003, and SBGC004 with which Seiko (all things considered, Grand Seiko) appeared the Spring Drive chronograph, the most complex mass-delivered Spring Drive movement – other mind boggling, considerably more complex Spring Drive manifestations incorporate this $50k+ 8-Day hand-wound and the unrivaled Credor Spring Drive Sonnerie .

Other variations of this Grand Seiko Spring Drive Chronograph incorporate the dark silver dial SBGC003 in steel, the more as of late appeared SBGC005 dark gold dial with indistinguishable case and arm band configuration however made from titanium, and to wrap things up, the mega uncommon and basically bonkers SBGC004 in 18k pink gold… yet it was the SBGC001 that was the “flagship product” Seiko picked when dispatching this movement and assortment. On the off chance that you don’t like the case plan, elective Spring Drive Chronographs incorporate the barely experienced SBGB001 and SPS003, two renditions with marginally different case sizes and no intense looking pushers.

The takeaway message here is that the Grand Seiko Spring Drive Chronograph SBGC001 has been underway unaltered since 2007.

The Spring Drive Chronograph 9R86 Movement

Seiko says that “from the absolute first steps” in building up a programmed winding Spring Drive it was among their objectives to build up a chronograph with high exactness. A bit more than two years after their dispatch of the principal programmed Spring Drive, they finally appeared the chronograph form with the 9R86 type in 2007. Seiko calls the 9R86 “by far the world’s most exact chronograph driven by a mainspring.”

Seiko claims that the 9R86, as found in the SBGC001 and its comparative looking other options, is precise to inside +/ – 15 seconds per month or inside a second a day – and these, as is consistently the situation with Seiko, are the most dire outcome imaginable reaches. The specific watch subject of this audit acquired 5 seconds in 3 weeks, which might actually be attributed to the extraordinary virus experienced during this period. I wore the Grand Seiko Spring Drive Chronograph SBGC001 on harshly cool days, down to – 15 Celsius (5F) which plainly is pushing the limits.

Still, for quite a while, I should state I was puzzled to see the seconds hand pass the zero imprint only a couple seconds off a long time subsequent to setting it to the moment bounce of the reference synchronized nuclear time I used.

Whatever survives from the 72-hour power hold is demonstrated on the dial at the 7 o’clock position on a scale split into three equivalent sections. In the previously mentioned Spring Drive article, I talk about finally the subtleties of Seiko’s Magic Lever programmed winding innovation, so until further notice I’ll simply state that it really works splendidly. Indeed, even a short stroll toward the day’s end can renew a day’s worth of hold as the excessively effective, bi-directional twisting never battles to wind the single-barrel mainspring in any event, when it is near being completely wound. Hand-winding is frightfully smooth too, with a scarcely perceptible mechanical clamor to it.

Remember the assertion I started this article with? All things considered, this movement humiliates so numerous “luxury chronographs” available today – I’m taking a gander at you, Audemars Piguet, and your embarrassing 3Hz, particular chronograph … for $28,000. Seiko’s 9R86 is a completely incorporated movement that comprises an astounding 416 sections, 50 gems, a bewildering 140 oil focuses and requires the utilization of five distinctive lubricants.

It offers three entire long periods of intensity hold, in any event, when you leave the chronograph running. Talking about which: the chronograph is outfitted with a vertical grasp, which all by itself is an uncommon, more complicated, more sturdy, and more exact grip framework than the even grasp you’ll find in practically any remaining chronographs at this value point (and numerous others, for that matter).

In most of chronographs the fourth wheel of the stuff train conveys another wheel over it – with these being straightforwardly connected to the stuff train, these wheels are continually turning. At the point when you start the chronograph, this continually turning wheel is pushed aside in order to work it with a wheel that is, at that point, fixed. As the teeth of the turning and fixed wheels “meet,” a major bounce of the chronograph seconds hand can happen, just as an unexpected strain on the whole stuff train and force delivery.

By contrast, a vertical grip is a little, about 5mm wide and 3mm tall, pile of different haggles and different components folded over a pinion. This goes directly in the focal point of the movement as at the top finish of the grip is focal seconds of the chronograph. It is called vertical on the grounds that the second you start the chronograph, circles situated over one another are squeezed together to begin driving the chronograph’s signs – and, alternately, when you stop the chronograph, the parts get isolated. Since there are no teeth to work, the second the discs’ level surfaces meet/independent, the chronograph begins/stops.

There is, obviously, a segment wheel likewise tossed in the blend for upgraded strength and perhaps the most strong inclination pusher criticisms ever designed into a mechanical movement. Chronograph signs incorporate focal seconds and an all the more extraordinarily positioned 30-moment and 12-hour aggregators on the right-hand side of the dial. As it generally ought to be, the chronograph hands are shading coordinated – every one of the three hands have been appropriately warmed, not painted, to get to a dark blue shine.

We’re not done at this point, however, in light of the fact that there’s a lot more to the 9R86 than just sheer performance. On show through a huge sapphire gem case-back, the movement tops off the huge steel case pleasantly. All enveloped by silver covering, the rotor and the plates include striped enhancements, with the last additionally donning wide, cleaned, straight-slanted edges. Being a completely coordinated type, you will see something other than an exhausting time-just base movement that has its chronograph treats on the dial side.

The 9R86 has a ton of profundity to it, as the chronograph hours and minutes counters and the cleaned segment wheel are unmistakably uncovered in their symmetrical format. It’s very sensational to perceive how at Seiko they even had the ability to focus on making the plan as symmetrical as could reasonably be expected, as the section wheel falls straightforwardly under the crown and the two gold-shaded wheels under the two huge pushers. A layer further down, you’ll see the tirelessly spinning rotor of the Spring Drive movement.

Finishing, at that point, is astoundingly acceptable, and it’s a major in addition to that everything is on show. One bizarre component to the completing is the means by which the edges of the stripes can mirror light in a manner that makes a rainbow-like impact: on the off chance that you have more straightforward light and take the watch off to have a superior glance at the movement, you’ll unquestionably see the bright lines stumble into the winding rotor and plates. A practically difficult to-photo (or to see) component is the very inconspicuous Grand Seiko words and lion insignia by one way or another faintly laser engraved into the focal point of the back sapphire precious stone. It’s strangely hard to see, yet it is there – simply one more one of the innumerable inconspicuous, marvelous, high-detail dashes of the Grand Seiko Spring Drive Chronograph SBGC001.

If you need much more prominent precision, search for watches with the as of late updated 9R96 movement – it is basically a similar watch just with significantly more thoroughly chose quartz gems that help bring exactness resilience down to a large portion of a second of the day or 10 seconds of the month. It’s accessible in the significantly more costly, titanium-earthenware SBGC013 with a blue dial, and the SBGC015 and SBGC017 with full artistic, but immense, 46.4mm-wide cases.

Design & Quality Of Execution

Coming in at 43.5mm wide and a powerful 16.1mm thick, the Grand Seiko Spring Drive Chronograph SBGC001 isn’t humble. It tips the scales at 187 grams on the full wristband – and despite the fact that that goes down extensively as you eliminate joins, it actually is one properly heavy watch. The SBGC line is the most complex of throughout the Spring Drive chronographs on account of its five-interface wristband that includes some cleaned components and the incorporation of a GMT hand (which isn’t accessible in the SBGB001). Let’s start with discussing the instance of the Grand Seiko Spring Drive Chronograph SBGC001 and work our way in from there.

Seiko has their own case make where they apply what they call a zaratsu finishing technique. Cases are stepped at 30 and afterward 90 tons just to be then CNC-ed with high exactness, completely eliminating any hints of the stepping method. The case at that point gets both brushing and high cleaning medicines, all applied by hand. The outcome is a case that has edges like not many others, altogether paying little mind to value point (downwards on the monetary stepping stool that is self-evident, yet I’ve took care of in excess of a couple of watches whose cases diddn’t come near this in spite of being considerably more expensive).


The wizardry component is in the freshness of the lines. Having seen case cleaning done right – and done quite gravely, whenever I was allowed to have a go at it – I can value exactly how much careful practice and how wonderful a method it needs to work metal with such refinement. The side of the case and the drags, just as the bezel all have a very profound and brilliant clean. Once more (and I realize I’m rehashing myself here), the sheen is so sharp and splendid that it really functions as a type of a focal point. As more viable subtleties are concerned, the bored drag openings are extraordinarily refreshing, while the odd, 21mm-wide carry structure isn’t. Now, it comes as nothing unexpected that the bracelet’s end-joins fit with careful precision.

Two flawless subtleties: the profile of the case is sunken, implying that its amplest point is further up and the case kind of “shrinks” towards the wrist. This decreases not simply the genuine actual zone it covers, making for a more comfortable wear, yet additionally the visual haul of the watch.

The arm band is fabulously comfortable, with no sharp edges, simply an ergonomic, secure fit around the wrist. These long catches like the one we see here I have blended sentiments about, as they gather and show scratches quite a lot more effectively than do more limited fastens. Another issue I have with it is the 4-choice miniature change: while it permits one to locate a pleasant fit, I do wish Seiko dedicated some time and exertion to making a slight and little miniature change that would find a way into this enormous catch. Not much, simply a 5-10mm device free change would help cause the watch to feel totally comfortable under all circumstances.
