Grand Seiko Spring Drive Snowflake SBGA211 There's a reason Spring Drive Snowflake is a Seiko fan favorite.high quality replica watches

The Grand Seiko Spring Drive SBGA011, better known to Grand Seiko fans as the "Snowflake", is probably the most iconic single model of the Grand Seiko Spring Drive, first introduced in 2010 (unbelievable). In the seven years since its release, it has become a fan favorite and a darling of critically acclaimed critics, acclaimed for its unique dial, and the overall fit and finish that characterizes the Grand Seiko. Interestingly, Grand Seiko never offered this dial with any other movement other than Spring Drive, in fact, the characteristics of the Spring Drive movement are crucial to the overall impact of the watch as a whole – whether it be a traditional automatic movement, Or a traditional quartz movement, wearing it on the wrist will be a completely different experience,

There are actually two parts to Snowflake's story: one is the general aesthetic, and the other is the Spring Drive movement. Snowflake is a very calming watch - subtle light changes on the dial, similar to the snow that has just fallen, and the blued steel second hand glide quietly and smoothly, together creating a feeling that time is flowing uninterrupted, but also Not in a hurry, one seems to see time from an almost eternal perspective, as one should see when meditating. Mechanical watches, by contrast, present time as a series of oscillations – the frequency of the balance wheel can be seen in the intermittent forward movement of the seconds hand, which moves with each swing of the balance wheel as the escape wheel is unlocked. Jump forward once.swiss watch replicas


Quartz watches work a little differently. Quartz crystals vibrate 32,768 times per second; this is done because quartz is a piezoelectric material—that is, it deforms mechanically when you pass it through it. Piezoelectric materials also generate electricity when mechanically deformed, which means you can easily count how many times the crystal vibrates per second (you just need to count the number of electrical pulses it produces). The reason for choosing the frequency is simple: 32,768 is 2 to the 15th power, and by repeatedly dividing the pulses from the crystal by 2, you can easily get a one-second interval. The integrated circuit that does the division then signals the stepper motor to advance the second hand one increment. This second jump is characteristic of the long-outdated double escapement, widely used in the Chinese market in the 19th century; in watchmaking, George Daniels commented, "This system was once highly regarded by the Chinese, who Despise the creeping seconds hand on a watch."

This is just to point out that the movement of the second hand naturally becomes an important part of our perception of the passage of time and the character of the watch. So much so that a watch with a jumping second — a so-called jumping second complication — is often despised by mechanical watch enthusiasts who find it too reminiscent of a quartz watch (even a Rolex's Nor is the name enough to make a complex business successful, witness the obscurity of the Rolex Tru-Beat). A high-frequency quartz watch can give the illusion of a smooth continuous movement, as can a high-beat mechanical watch, but Spring Drive is the only watch technology with true continuous forward movement.luxury replica watches

The evolution of spring drive
As with any fundamental advancement in timing technology, Spring Drive's gestation period was long and sometimes painful. The original idea was by Yoshikazu Akahane, an engineer at Seiko Epson in Shiojiri, Nagano Prefecture (now known as Shinshu Watch Studio to reflect its focus on Grand Seiko Spring Drive and Grand Seiko quartz watches; it is also home to the Micro Artist Studio) first proposed. , making high-end Spring Drive watches such as the Eichi II and Credor timekeeping complications). Akabane began experimenting with the idea in the late 1970s (dates are usually given around 1977) and issued the first patent for the concept in 1982. However, it wasn't until 20 years later that Seiko publicly demonstrated the movement, at Baselworld 1997. In 1998, the first commercial Spring Drive watch came out.

It took so long for a few reasons. There is a quartz oscillator in the Spring Drive movement, but the similarities between it and a traditional quartz watch end. Quartz watches have batteries; Spring Drives don't, and, quartz watches may or may not have hands—as HODINKEE Contributing Editor Joe Thompson points out, many of the earliest commercially successful quartz watches were digital, not analog— In Spring Drive, hands are essential (it is not possible to build a digital display Spring Drive watch). Additionally, Spring Drive watches are powered by a mainspring; there is no equivalent in quartz watchmaking. The closest is probably Seiko's Kinetic and Swiss Autoquartz movements, but these are standard quartz watches with the addition of a rotor-driven micro-generator that charges a rechargeable battery. In fact, Spring Drive watches are technically indistinguishable from any other mechanical watch, not even the position of the escape wheel in a standard watch movement.Audemars Piguet replica

The location of the escape wheel, lever and balance wheel in a traditional watch, we find what Seiko calls a triple-synchronizer. "Three" refers to the three energies present in the regulating system: magnetic, from the pulley; mechanical; from the mainspring; and electricity, from the quartz crystal. The last gear in operation turns the so-called skid wheel, which has a permanent magnet at its hub. This turns between two electromagnets located at one end of a pair of wound coils, and the whole device acts as a generator (the pulley acts as a rotor) according to Faraday's law, which says that a conductor in a magnetic field will generate an electric current.

The resulting current flows to the integrated circuit and the quartz crystal, when the current passes through it, the quartz crystal vibrates and the IC calculates the oscillations. However, instead of dividing by two until the one-second interval is calculated and then sending a signal to the stepper motor, the IC transfers energy back to the electromagnets around the skid wheel. Here, the electrical energy is turned into a magnetic force, which applies braking energy to the skid wheel; the electrical energy that is fed back is precisely controlled so that the skid wheel turns precisely eight times per second. Thus, the pulley ensures that the mainspring unwinds in a controlled manner, just as the escape wheel, lever and balance wheel (and hairspring) of a traditional watch control the rate at which the mainspring unwinds.

So, in essence, the Spring Drive movement is mechanical, but with an electromagnetic escapement regulated by a quartz oscillator. One of the reasons Spring Drive has been in development for so long is that it produces very little energy. To be used in a commercial watch, a special low-energy integrated circuit had to be developed, and the coil had to be wound with very fine copper wire to ensure the maximum number of turns. the coil itself. For this purpose, a special type of wire with a hexagonal cross-section was developed, allowing the coil to be wound with no gaps between the turns of the wire - even tiny gaps, meaning a greater overall length within a given volume . You can actually see with the naked eye the difference between the coils used for Seiko Kinetic watches (where the battery is charged by a mechanical rotor) and the Spring Drive coils; on our recent trip to Shiojiri we were able to photograph both coils side by side.Richard Mille replica

The electricity produced is tiny; one way to visualize it is to imagine that everyone on the planet is wearing a Spring Drive watch. If so, the electricity produced is only enough to light a 100-watt light bulb. In order to obtain an acceptable power reserve, the entire system must work very efficiently, which is why it is necessary to develop new coil systems as well as highly efficient integrated circuits. Mechanical drive trains must also be manufactured and assembled with very high precision to minimise frictional losses (this is something Spring Drive can easily miss, but for them to work they require high precision mechanical watches as well as advanced technology platforms) .

The question is often asked, "Isn't the Spring Drive a quartz watch?" No, at least not as we usually think of a quartz watch. The electromechanical drive system in Spring Drive is regulated by a quartz crystal, yes; however, as a category there are many fundamental differences between Spring Drive and a quartz watch, it is indeed a different technology. At the end of the day, the Spring Drive isn't a mechanical watch in the normal sense, but it's not a quartz watch either - it's a Spring Drive.

Snowflake Dial
The texture of the Snowflake dial is often comparable to that of fresh snow, but it's not really a snowfield, of course - it's not really anything, which is part of what makes it so striking. It comes in a lot of different things - like the texture of watercolor paper or rice paper screens - and it doesn't fit anything in particular, which means it looks and feels different for everyone. It's also very Japanese - a lot of the aesthetics in traditional Japanese culture are about what you leave out, like what you put in.

Of course, the dial is not an ink painting, but some of the same aesthetic standards are at work in this case. The composition must be balanced, but not static, and the negative space must be offset by enough contrasting elements to keep things dynamic without becoming cluttered. As far as providing dynamic elements, the single most important element on the dial is the power reserve, which is positioned and executed in a way that breaks up the dial's surface texture – which would otherwise look a little too monotonous – and balances the presence of the date window. Of course, another big part of the dial's appeal is the contrasting textures—the diamond-bright reflective surfaces of the hands contrast with the snowflake dial surfaces, and the blued-steel seconds hand slides silently across the whole thing. One of the most appealing aspects of the watch is that its design elements don't give the impression that special effort has been made to create the effect; it looks natural and effortless.https://www.chronowrist.ru



The making of the dial is a multi-stage process that involves stamping the initial pattern onto the dial blank, then adding successive coatings to create the subtle translucency of the final dial. The hour markers on Grand Seiko watches are cut with a diamond-set rotary cutting tool, supervised by a technician who manually operates the cutting machine, and a small hand mirror is used to ensure that the hour markers surface reflects light in the desired way. Once the lettering is printed, the markings applied, and the date window inserted, the dial can become part of the watch. Snowflake dials are labor-intensive, but not inferior to many other dial-making processes at Shiojiri Shinshu Watch Studio; the manual work for dials, hands, and markers is extensive,

As we said at the beginning, the Spring Drive Snowflake SBGA211 is a very stable watch. The whole thing seems to be designed to have a serene and not boring effect. Minimalism is not sterile. At its most basic level, wearing it is an exercise in experiencing a watch, it absolutely fulfills the most basic social contract of a watch, and a watchmaker, has an owner: it is instantly readable, in absolute clarity way to convey all information, is very accurate, and is useful and usable under almost any condition you can reasonably expect it to meet. Not only is there no compromise on functionality, functionality is actively pursued as a goal that is meaningful in itself, again by pursuing functionality to achieve aesthetic effects, rather than trying to create effects, by itself, it has no place in traditional Japanese culture No - perhaps nowhere is more iconic than the Japanese sword. The most basic question with a katana is not "how does it look" but "does it work?" but its appearance is of course a direct result of how it works so well.

This year Grand Seiko became a separate Seiko brand from Seiko as a whole, which means Snowflake now no longer has the Seiko logo at 12:00. The Grand Seiko logo has been moved from the original 6:00 position to the 12:00 position so the entire dial is less cluttered - "Seiko Grand Seiko" watches are always a bit redundant in a way The differences between the different models are very Great, but for Snowflake I think this change is a definite improvement and does give the dial a sense of serenity that wasn't there before.best replica watch site 2022

Wearing Snowflake is also an exercise in achieving impeccable functionality. The case and bracelet are Seiko's "High Intensity" titanium, which has the lightness, comfort and hypoallergenic properties of titanium, but with better scratch resistance. Although the case bevels and bezel are polished to a bright finish, you shouldn't have to worry about getting noticeable scratches on this watch when wearing it, despite its somewhat large Grand-Seiko diameter (41mm x 12.5mm for the case) ( The case is 41mm x 12.5mm) and is comfortable to wear—adjusted to fit slightly around my seven-inch wrist, it becomes barely noticeable unless I happen to need to check the time or date.

final thoughts
I think this is one of the most satisfying watches out there. Yes, it is objectively excellent as you asked in pursuing the real interests of the owner. Seiko officially rates the accuracy at one second per day, but Grand Seiko Spring Drive owners are said to generally rate the accuracy much better—often an order of magnitude better. It's easy to wear day in and day out; reading the time couldn't be easier - even in very low light, thanks to the bevels and highly reflective surfaces on the hands and hour markers, you'd think some luminescent material was a must Indispensable, tell time is short. At the same time, however, you can also approach and appreciate the watch in terms of its technical representation. Spring Drive takes some time to understand, but it's worth the effort to see how different it is from traditional quartz watches and standard mechanical watches, if you find the technical achievements and innovations of independent timekeeping interesting (that is, not radio time signals or GPS control) Spring Drive is one of the most interesting developments since Seiko introduced the quartz itself in 1969.

However, where Snowflake has really won hearts, and has won hearts for nearly a decade, is in its design and aesthetics. The perfect fit and finish you'd expect from a Grand Seiko is a big part of it, but as with any truly successful design object, the whole is far more than the sum of its parts, and as a design object with a unique design Japanese At heart, Spring Drive Snowflake is a well-deserved favorite of Grand Seiko fans. Grand Seiko is known in the world of watch lovers as a symbol of quality, and within the Grand Seiko family, the Snowflake watch is particularly striking, which highly successfully integrates the many qualities that make Grand Seiko so appealing – an icon sign, if you will.
