Opinion: Why the Grand Seiko SBGX069 / SGBX269 is a quartz watch you need in your collection

Pinterest LinkedIn Tumblr +

To many, Seiko is synonymous for their functional yet affordable timepieces. But at the top end, they have the Grand Seiko line, first introduced in 1960 and in 2017 became a brand of its own right. Grand Seiko has relentlessly pursued the idea of creating the perfect wristwatch. The subject of our discussion is the Grand Seiko SBGX069 / SBGX269, with the 9F quartz movement, and we think they might just have succeeded.

Disrupt or be disrupted: it seems that innovation paves the way forward. And no one does innovation better than Seiko; they’re the forefront of technology intensive and value-added timepieces. In 1969, Seiko released the revolutionary Astron: the first production quartz wristwatch, beating the Swiss at their own game. It sold for ¥ 450,000, which was roughly equivalent to the cost of a Toyota Corolla at that time. It was a lot of money, especially back then, partly due to its massive development span of over 10 years. This resulted in poor sales, with only 200 produced. However as with any technology and time, industralisation followed. This caused prices to fall and soon quartz became the choice of the masses, upsetting the Swiss watch industry. This was the phase which we now know as the Quartz Crisis.

The release of the first Grand Seiko Calibre 9F in 1993 created a big buzz among collectors. By then, quartz has become a more affordable alternative to intricately handcrafted, handsome mechanical movements. And to many, the idea of a high-end quartz watch may seem absurd; a paradox. But when a brand is adamant in their pursuit for perfection, we pay attention: the calibre 9F may very well be the best quartz movement ever created.


The Grand Seiko SBGX069 / SBGX269

As a case in point, we consider the Grand Seiko SBGX069. This model is now renamed SBGX269 with the Grand Seiko branding, but is essentially the same watch.

We shall start with the movement.

The movement: the 9F

As with all modern Grand Seiko Quartz watches, the SBGX069 uses the manufacture Calibre 9F.  The 9F is a product of the Seiko Epson based in Shiojiri. For a more in-depth look at the two Seiko manufactures, please see this article here.

The SBGX069 / SBGX269 features the calibre 9F62. As the SBGX069 does not have a display case back, and we did not open the case back, we could not examine the movement during our hands-on session. But we do know how the movement looks like as our Chief Editor have examined it during his visit to the factory. 


The Grand Seiko lion graces the solid case back of the SBGX069. The lion represents Grand Seiko’s commitment to be “King of watches”.


Unlike the industrialised robotic assembly where most quartz movements are made, the 9F is hand-assembled, hand-finished and hand-decorated. Built more like a mechanical movement with only the visible battery and coil serving as a reminder of its electronic heart. The 9F looks the part of a proper haute horlogerie movement.

So it is safe to say that the 9F is not your typical quartz movement. It also contains more components than a generic Swiss automatic movement and built to a higher standard. The assembly requires the talent of 2 expert craftsmen – one to assemble the movement and another just to install the date indicator.

This perfectionist mindset is exercised right down to the installation of the hands. With a mere 0.2mm separating them, only the most experienced craftsmen are entrusted with this detail.


Every single component of a Grand Seiko right down to the installation of hands and date indicator is done with a perfectionist mindset.


The attention to detail is manifested even in the minute details. Seiko’s quartz crystals are grown in-house, with only the purest selected. To ensure consistency in its performance, each individual crystal is aged for up to 3 months, and, paired to a temperature sensitive integrated circuit that adjusts its frequency 540 times per day. The result? A guaranteed class leading performance of +/- 10 seconds per year. True that this level of performance is not the best in the world, but it is extremely good, and achieved by only a handful.

Moreover, if there are any irregularities in timekeeping, the 9F can be fine tuned through its pacing switch similar to any mechanical movements.

What ascertains the calibre 9F as one of the best quartz movement in the world is its unrivalled 50 years’ service interval. This is because Seiko seals the movement in what they call a “sealed cabin”. What this means is that the movement is vacuum sealed within a cabin exterior. And gives it the extraordinary service interval. Probably the highest we have ever encountered. Of course this interval is theoretical. The air tight seal might preserve the lubricants for this long, but as the 9F is only 25 years old, it has not been tested yet. Seiko recommends a standard service interval of 3 to 5 years for the watch despite this theoretical service interval.  We recommend only to service a watch  when it is not running properly.

In a typical standard quartz watch, the movement is replaced during service and not service, while the calibre 9F is designed to be serviced in the long run.


The “sealed cabin” as depicted here houses two of the most important parts of the 9F: its gear train and stepping motor. An air-tight seal prevents debris from entering the movement when it is exposed. It also helps to preserve the lubricant, allowing for its unrivalled 50-years service interval.

Another interesting aspect is the lengths Grand Seiko takes to ensure that each step of the seconds hand aligns itself to the seconds marker exactly. To ensure this, GS uses a special hairspring to tension to prevent backlash or vibration. The result is the 9F has a more assertive “jump” in the seconds hand.


The special hairspring as depicted here is used in the backlash auto-adjust mechanism, allowing it to stabilise the seconds hand with every jump. Picture credit: Joe Kirk.

Despite the performance and qualities it boasts, it still has a reasonable 3 years battery life which makes for a good daily driver. Changing the battery will not require the movement’s sealed cabin to be opened.

The case, dial and hands

Crafted using Seiko’s proprietary Bright Titanium alloy, the Grand Seiko SBGX069 / SBGX269 measures a comfortable 37mm diameter and 10mm thickness. 


The Grand Seiko SBGX069’s Bright Titanium case measures 37mm in diameter and 10mm in height, weighing in at 79 grams.


The design language used in the SBGX029 is set out in the Grammar of Design pioneered in the 44GS. The case detailing is what you’d expect of a typical Grand Seiko: a blend of traditional Zaratsu and brushed finishing. No corners were cut, with the famed Zaratsu polishing being meticulously applied to every aspect of the watch. The polished bezel and case sides, fused with the brilliant brushed lugs gives it a bright and seductive appearance.

On handling the watch for the first time, it has the light (79g, watch including bracelet) yet robust feel of the titanium and leaves a deep impression. With a bracelet forged from the same alloy, it makes for an excellent daily driver. It sits well on an average wrist and is no doubt a convenient grab-and-go everyday piece; easy to slip on and unobtrusive. 


The Bright Titanium bracelet and case allows for a light yet robust feeling watch, perfect for daily wear. The bracelet deserves a special mention as its included half links allows for more precise adjustments, making for a more comfortable fit.


The SBGX069 features an intricate and enchanting pattern imprinted on a gorgeous black dial. This model features the now discontinued ‘Seiko’ branding at the top, instead of the ‘Grand Seiko’ branding (announced at Basel 2017) which is on the SGBX269.

Perhaps the most indispensable feature of any watch lies in its ability to tell the time. This model sports beautifully polished, consistent golden blade-edge hands. There is no applied lume, but the high-polished finish on the hands reflects light brilliantly, making time telling effortless in all but the darkest situations.


The highly legible, Zaratsu polished golden hands.


The breath-taking attention to detail extends right down to the applied gold indices: they are polished individually by hand, using the same Zaratsu technique as the case. The result is an exquisite, brilliant angular surface with high lustre, adding to its charm. And that’s just the tip of the iceberg – zoom in closer and you’ll notice the vertical stripes on each of the 11 indices. It might be a form of over-engineering as they’re barely noticeable on the wrist but serve as a true testament to Grand Seiko’s pursuit for watchmaking perfection. 


Attention to detail: Vertical stripes present on the zaratsu polished hour markers.


The golden hands and indices contrasts pleasantly with the intricately patterned black dial, giving a sophisticated and elegant feel to the watch. Overall, the dial is clean and legible.

Concluding Thoughts/Remarks

The SBGX069 / SBGX269 is as you’d expect with all other Grand Seiko watches, built with the idea of perfection in mind. Its sleek, full titanium construction, as well as a highly legible and gorgeous black dial makes it perfect for daily wear. The quality and finishing are on par with the Grand Seiko mechanical timepieces, only it features the convenience and benefits of quartz technology. And, with the watch coming in at a conservative 37mm, it is perfect for all but the largest of wrists. Priced at S$ 4,494 / JPY 340,000 for the SBGX069, Grand Seiko delivers a superior product with excellent value.


On the wrist, the SBGX069 at 37mm makes a comfortable fit for most. Its curved end links allows it to hug the wearer’s wrist, allowing the watch to sit well. However, it might not suit the largest of wrist.


In terms of competition by similar quartz pieces, the calibre 9F might be compared to the likes of the Citizen CTQ57-0953 Chronomaster, nicknamed simply “The Citizen,” or the Longines’s VHP. Both have movements which are accurate to +/-5 seconds per year, making them more accurate than the 9F. The Citizen CTQ57 is a remarkable watch, and will be the subject of an in-depth investigation. But we digress. We think, however, that the Grand Seiko is in a league of its own when it comes to fit and finish. It is able to pull its own weight, and is worth checking out. We highly recommend that you do.

    I am a proud owner of a SBGX069 what an incredible watch, the black and gold just drew me in. I bought it from Japan it is a 2014 model. Just my personal opinion I have owned two Chronomaster’s, the chronomaster is a very accurate watch as an overall watch they do not compare to the Grand Seiko.
    The fit & finish of a Grand Seiko easily Rolex standard.

  2. I’am a lucky owner of the SBGX069. I love it, and wear it every day. I think I’am the only one in Skandinavia with this watch. Love the articel, by the way????????

  3. Just another guy on the web on

    Grand Seiko are what Rolex pretends to be. Truly exceptional watches with a conversatism, elegance and intelligence which few other watchmakers can match.

  4. And whilst putting together your next piece on the A660 and A010, perhaps mention the newly announced 0100 – Citizen’s astonishing 8.4 MHz, thermocompensated movement spec’d to +/- 1 second per year. For some reason this has got almost no media traction whatsoever. It is creating quite a stir on the forums, though.

  5. I am a proud owner of GS SD and love it but personally don’t like battery-based watches in this price range and with limited options of authorized dealers. My main concern is getting the case back opened every time when a new battery is needed and no authorized dealer in the State where I live. This is just my opinion, don’t mean to offend GS 9F owners. Indeed it’s a beautiful watch, just not my cup of tea.

    My Grand Seiko quartz is still accurate to within +1sec. a year since l bought this
    great watch about 6 years ago.
    It’s the real reference! Mine is in stainless steel, I prefer the heft.

  7. I love my 9F. I loved my last one, too. Grand Seiko quartz are truly superbly made. My current quartz GS might, however, be my last one if they don’t update the woefully outmoded calibre. First of all, the fifty year service interval is a myth. They say that the movement could theoretically go for fifty years without needing new oil, but the literature still recommends servicing every 3 to 5 years. Heck, the battery lasts only about that long, so someone is going to need to open the thing up sooner than fifty years anyway, and if you want your timing adjusted, your seals replaced and your water resistance retested then regular maintenance is obviously important.

    Besides this, though, the cal. 9F still has not got an independently adjustable hour hand or a perpetual calendar or a date that changes at midnight. Go compare it to a Citizen Chronomaster, with its 5 SPY rating (vs 10 SPY for the GS) and its host of technological advances and then come back and tell me again that Seiko’s 9F is top dog.

    I have a few high accuracy quartz watches and my Grand Seiko remains a firm favourite, but it is important to be open about the deficiencies of this aging movement.

    • Thanks for your comments Tom. We have edited the article to clarify that the 50 year service interval is indeed theoretical. However, our standard recommendation is that a watch should only be serviced if it is not running properly, and this also applies to the 9F. We are aware that this is contrary to manufacturer recommendations for service.

      When replacing the battery, the sealed cabin is not compromised, and the lubricants remain sealed in the air tight movement cabin. Seals on the case are replaced, and water resistance testing performed during battery changes.

      Thank you for also mentioning the Citizen Chronomaster. We also noted that the Citizen and the Longines VHP has a higher accuracy in the last paragraph of the article. We will be exploring the Citizen A660 and A010 in an in-depth article in the later part of 2Q2018.
