Grand Seiko Blue Snowflake Reference SBGA407: On The Wrist
The Grand Seiko Spring Drive is a quartz watch. Wait. No. Okay. It’s a battery-operated watch. No again. It’s somewhat of a hybrid. No owner of a Grand Seiko Spring Drive will ever change batteries. There are none.
While it doesn’t have the precision of a pure quartz watch, it’s among the most accurate mechanical watches in the sub-$10,000 market (+/- 1 second per day or less; my experience was less).
That’s what interested me about the Grand Seiko Spring Drive. GS is known for its craftsmanship, basing its micro-mechanical designs on tolerances down to one-hundredth of a millimeter (think less than the diameter of a human hair). The final adjustments and refinement of the components are all completed by hand.
Grand Seiko maintains that no machine can match the skill of its craftspeople; their skill gives Spring Drive its extreme precision. After spending some quality time with it, I agree.
With this introduction, I wanted to learn a little more about the Spring Drive. Specifically, one model that caught my eye: the Blue Snowflake. Some call it the Skyflake, since blue snow is hard to come by.
So we rang up Grand Seiko and asked if they might lend us a watch to try. No. Sorry. Apparently, the Blue Snowflake is too popular to send to the media. But we can send you a non-working example. No, thanks.
I walked into the Beverly Hills Grand Seiko boutique and chatted up the manager Alexander Friedman and his associate, Xavier Sanchez. They were as nice as they could be. And, yes, they just so happened to have a Blue Snowflake – it had arrived two hours previous and, lo and behold, wasn’t yet spoken for. Lucky me.
After a week on my wrist, here are my impressions of this watch. Fair warning: I fell in love with it on several levels. Yes, there are some things I’d change, which I’ll get to. However, these are minor compared to what this piece has to offer especially at a price point of $5,800.
That is by no means inexpensive. However, sub-$6,000 barely scrapes the entry level for many manufacturers.
Grand Seiko Blue Snowflake: dial
The dial is manufactured in-house, in the company’s Shiojiri dial workshop. The snow-like effect comes from stamping the pattern onto a dial blank and then adding several layers of slightly translucent coating to reveal the texture beneath.
The technique is similar to the way the Japanese make traditional water paintings. The result is the rough appearance of a snowy field you see on the dial.
There are those who prefer no power reserve indicator here. For purists, its presence just blows the whole Zen effect. Some, on the other hand, may grudgingly accept the date window. They may not love it, but it’s not a deal killer either.
I understand. Without these two distractions the dial would be totally free of clutter, and we could enjoy the unobstructed view of the second hand gliding across the blue snow field. Wouldn’t that be something?
The power reserve meter correctly rises from bottom to top as the watch winds down. Facing the left dial side, the indication moves in a clockwise direction so that all hands rotate in the same direction. It would have looked odd the other way around.
There’s always a reason
Several in the business told me that there’s a reason for everything Grand Seiko does. Who am I to second guess the GS designers?
Still, I think they could have put the power reserve indication elsewhere or abandoned it entirely rather than clutter the beautiful dial. Repositioning or removing such an element of nonessential information makes sense to me given what I learned about the Spring Drive:
- If you keep it on your wrist or in a winder it will never run down, just like an automatic watch.
- If you pick up a watch you know has a power reserve indicator, you’ll glance at it before putting the watch on to see if you need to wind it. Right? Regardless of where the indicator is located, you still get the same information.
- As long as the Spring Drive is not at a dead stop, when you put it on it’ll wind right up in no time and you won’t have to even look at the power indicator for three days.
The hands and hour markers have wide and flat surfaces. Their highly polished, mirrored edges catch and reflect even the smallest rays of light. Together, dial and hands combine to create a very readable dial under most any light conditions.
The second hand turned out to be one of my favorite features. It is blued steel. Depending on the light, it transcends from black to an electric blue. And it doesn’t jump from second marker to second marker like quartz watches; thanks to the Spring Drive, it sweeps in a single unrelenting, uninterrupted glide across the “snowy” blue dial in a much smoother way than even a high-frequency mechanical watch.
The 11 rectangular markers receive the same beveled mirror polishing, which allows them to work with the hands to reflect even the smallest amount of light. Truly, the ability to actually read the time in very low-light conditions is remarkable.
So far, the design vocabulary remains consistent. The date numbers are in a thin black font against a white background. I can’t be certain, but I’d say it uses the same font as the “Spring Drive” verbiage on the dial.
A nit-picky point here: I wonder why the designers chose to use a white background for the date window rather than matching the dial’s blue. Even the power reserve indicator uses the dial’s blue. Giving the same treatment to the date window makes sense to me.
The case design is pure classical elegance. All surfaces have the brand’s own Zaratsu mirror polish. The lugs curve gracefully downward, giving the watch the perfect size appearance for my wrist.
Grand Seiko added a sapphire crystal display case back to show off the Spring Drive movement. Brilliant. Caliber 9R65 Spring Drive is an enormous technical achievement that everyone wants to see. The rotor along with some of the movement is decorated in what the Internet has taken to start calling “Tokyo stripes,” but what I would love to dub “Shinshu waves.”
With its blue crocodile skin strap, this is most certainly a dress watch that works for casual as well.
A box-shaped sapphire crystal is slightly convex and rises above the mirror polished bezel. Grand Seiko’s decision to use the more costly box crystal is testimony that no expense is spared in designing and manufacturing this piece. The crystal also has an anti-reflective coating inside. This works nicely to remove exterior glare, allowing the dial furniture to sparkle.
Strap and buckle
The strap is blue crocodile with blue stitching. It’s a nice strap – high quality and quite comfortable. However, there are two issues that remain unexplained as to the strap and deployant buckle designs.
First, the strap ends in a blunt curve. Why have such a boring end to this story when the entire design vocabulary on this watch bespeaks precision punctuated with sharp, pointed hands and perfect mirror finishes? Even the markers speak this language with their sharp, diamond-cut, right-angled corners. So why put a blunt end on the strap, one of the only parts we handle every day?
Second is the buckle. It’s a nice, serviceable deployant buckle in stainless steel. The two-fold mechanism works well by pressing two buttons on either side. The buckle hardware carries the same mirror polishing as the case and dial furniture.
It’s a nice touch. But there’s a brush-finished steel loop affixed to the buckle that the strap end passes through. This metal loop makes changing the strap length by passing the end through the loop a pain.
I believe I understand why Grand Seiko chose to use a steel loop here rather than the more commonly used leather. It’s to protect the more delicate polishing of the buckle in an area whose surface is exposed to constant wear and abrasion.
The result is that the entire deployant buckle is thicker than need be. Couple that with the long tail of the OEM strap and there’s far more attention drawn to this part of the watch than necessary. You cannot rest your wrist on a flat surface without feeling the steel loop’s uncomfortable bump beneath.
Further, the inner wrist side of the watch appears lopsided with both the long excess strap and the steel loop of the buckle bulging out.
Caliber 9R65 Spring Drive is currently the most standard of Grand Seiko’s 9R Spring Drive movements. Since the Spring Drive’s advent in 1999, the power reserves on these have steadily improved. Today, the piece I’m reviewing has a 72-hour power reserve that automatically winds with the barest of wrist movement.
Here’s what I learned of how the Spring Drive works. First, it has no batteries but does generate its own electrical current. This current comes from the mainspring unwinding. Think of how the generator for a bicycle light generates current as the wheel turns. Similar thing here.
Spring Drive consumes the electrical current equivalent of 1/300,000,000 of that used to power a single LED bulb.
A quartz oscillator and an integrated circuit-controlled rotor use the electrical power. The quartz oscillator vibrates at exactly 32,768 Hz, transmitting a precise reference signal to the integrated circuit, which compares the reference signal from the quartz oscillator with the revolution speed of the glide wheel turning in only one direction (clockwise, of course) rather than back and forth.
That’s how the second hand moves with a Zen-like smooth motion over the textured snowy dial.
The integrated circuit applies a magnetic brake when the glide wheel spins too fast. This regulates movement of the hands with a precision not seen before in mechanical watches.
Grand Seiko says this watch is accurate to +/- 1 second/day and +/- 15 seconds per month. The company also says that owners often experience better rates. That was true of my time with the Blue Snowflake. It was accurate to one second ahead during the entire week I had it – on my wrist and in a watch winder.
This watch is no Rolex Submariner. So, yes, it does require more care in the handling of it. Then again, it wasn’t designed for the environments the Sub was.
Grand Seiko recommends not allowing the sun to beat down on the dial for extended periods and not exposing the watch to temperatures below 5°C or above 35°C.
Also, keep the watch away from areas of strong magnetism and static electricity. Keep it out of dusty environments. Don’t expose it to high humidity. And finally, no strong vibrations, please. Of course not. There’s a quartz crystal inside vibrating away at precisely 32,768 Hz.
But it is water resistant to 10 bar and without a screw-down crown.
The Grand Seiko Blue Snowflake is an extraordinary timepiece. It’s beautiful. It’s uncommon and rare. Its design appears simple yet is singularly complex.
For me, the Snowflake is a work of art created by some of the industry’s finest artisans. The few problems I found are easily remedied, and I can live with those that aren’t. After enjoying it for a while, I’m beginning to think this watch deserves a place in my modest collection.
