Seiko Cal.9R86 Solitary Last Samurai

There is no doubt that SEIKO's technical skills on this route are far beyond the reach of the vast majority of professional watchmaking Swiss watchmakers and the 9R86 is the highest achievement of the SD program, We have the need to discuss it here.

Spring Drive (hereinafter referred to as SD) may be the most special invention in the history of modern watches, its purpose is to develop the combination of mechanical watches and quartz watch the merits of the general mechanical watches to control the left and right balance wheel swing time, but when Power gradually weakened, winding torque becomes smaller, it will affect the accuracy, and then frequent 28,800vph the seismic frequency, can also cause parts wear and tear, and SD one-way operation of the magnetic wheel to replace the traditional escapement structure, the substantial advantage Mainly in the quartz watch to maintain the accuracy of both the power of the clockwork both torsion, torsion big words more able to drive multi-pin, complex structure of the function is conducive to the development of high-end complex features watches.

Now referred to SD often refer to a rather ambiguous information that it is Seiko Seiko R & D for nearly 30 years of technology, in fact, although the concept of the time in the 1970s and 80s submitted but the end of the ninety years of between actual product, SD plans have repeatedly been shelved, when the number of R & D SEIKO real investment should be around 5 years. Looking back to the era when the SD program was just proposed, it was the pinnacle of the development of quartz technology at that time; how to miniaturize the components and use the power more effectively is a continuous improvement project in the development of quartz technology, and it is no exception today , the focus of the early eighty's internal SEIKO movement developed naturally focused on this one, this agency will send come up with SD in this space-time background is not surprising, but also just one of many internal SD SEIKO R & D projects One, soon after their attention turned to Solar Solar Power and Kinetic Solar Power, the SD project was shelved.

SD really back to the table again after the 90s, but this time SEIKO expectations of it is no longer as the evolution of the quartz movement, when the revival of the mechanical watch has been up, the table world has gradually begun to fine , SEIKO re-proposed the purpose of the SD, on the one hand is to get in touch with the mechanical watch, on the one hand want to create an exclusive technology, so that they can gain a place in this new market.

The next ten years SEIKO play is almost this topic, but from the results, we can almost concluded that SD can not meet the expectations of SEIKO at the beginning, the advanced watch market has evolved to a good or bad product eventually Can not decide the success or failure of the brand. However, SEIKO demonstrated in this way the technical force is beyond doubt, it is the vast majority of known professional watchmaking Swiss watch factory far behind, and this 9R86 is the highest achievement of the SD program , So we have the need to discuss it here.

Spring Drive the real culmination

When it comes to the highest achievement of SD, some people may think it is CREDOR's small self-willed, wise or questioning table; Of course, these high-level complex functions are very good works, but here we are a movement The emphasis is on its versatility and expansibility, and SD has shown quite strong strategic intentions since the very beginning, so the real meaning of the 9R86's basic chronograph movement is indeed even more significant. The actual product line from the development point of view, the introduction of 9R86 in 2007 is also the push SEIKO peak SD, follow-up and continued the introduction of new models.

Long time off the mechanical chronograph movement

9R86 SD is of course the first chronograph movement, but in fact before SEIKO also in a long time did not launch mechanical chronograph movement; 9R86 SEIKO before the only mechanical chronograph movement only 6S series, and 6S series is 1998 Their home has just returned to the mechanical watch battlefield launch, after the millennium launch 6S series of products reduced year by year until the eve of 9R86 launch SEIKO mechanical chronograph only a handful of CREDOR only, so the industry view 9R86 attitude , Not so much the first SD movement, as it is a long time ago SEIKO mechanical chronograph movement.

All zero research and development

The 9R86 features column wheels and vertical clutches, which now appear to be the basic specification for the new generation chronograph movement, but the benchmark was just shaped in the industry at the time the movement was introduced; SEIKO traced back in emphasizing this point Cal.6139, introduced to their home by the automatic chronograph movement in 1969, is claimed to be the first chronograph movement in the world to be vertically clutched. However, in fact, How Know How mechanical watches were made by SEIKO almost immediately after the quartz revolution Completely interrupted, in 1998 their research and development 6S line is almost from scratch, and 6S is the level of clutch, so 9S86 R & D is all over from scratch.

High-end movement of the shelf

SEIKO three active chronograph movement, 9R86 and 8R28 are column wheel + vertical clutch, but if the zeroing mechanism into account, the 8R28's functionality may be more excellent; although the 6S system is 14 years ago Product, the operating feel is the best of the three. However, compared with the other two, 9R86 more high-end movement of the rack, it's board the most practiced, the most beautiful polished, but also the most difficult to create, the full 416 parts, or even beyond a lot of high Complex features, coupled with the scarcity of SD itself, so 9R86 with the watch is one of the highest price of three.

Wanjian Qifa the product layout

In the first few years of its launch, the 9R86 was heavily involved in several product lines. In addition to the original GS, GLT and Seiko Spring Drive from the beginning, several special products such as Izuru, Spacewalk and more were specially developed for the 9R86. These special products cleverly utilized 9R86 unique face plate configuration, it is indeed a few years the industry is quite worth mentioning the watch, but after this the focus of SEIKO transferred to mechanical watches, SD's new product has decreased year by year; 9R86 is SD's ultimate product, but In my opinion is also the stop loss point of the SD program, after determining 9R86 still can not lay the market for SD, SEIKO also simply let go.
