Time passes by all too quickly. It had been 5 years since the quartz watch that astounded the world, the ‘Seiko Quartz Astron 35SQ,’ had been brought to market. The quartz watch had already become an indispensable tool in people's daily lives, and had become widely popularized. However, awaiting the top manufacturer at that time, Suwa Seikosha Co., Ltd., was a difficult period of stiff competition from rival companies. It had been crucial that the company continue making quartz watches even more compact and affordable, in order to maintain the dominant position it had held until then. However, tuning fork crystal units, the very heart and soul of these watches, were already as small and cheap as technological limitations would allow. How could they overcome the impending crisis? The solution they eventually chose was the implementation of a completely unknown technology. This second installment of ‘The QMEMS Story’ will explore the efforts of the engineers involved in the technological development of QMEMS' origins.
时间过得太快了。自石英手表惊世骇俗的5年以来，“精工石英天文35SQ”已经上市。石英表已经成为人们日常生活中不可或缺的工具，并且已经广泛普及。然而，等待当时的顶级制造商，苏瓦株式会社有限公司是竞争对手公司竞争激烈的困难时期。至关重要的是，该公司继续使石英表更加紧凑和实惠，以保持其迄今为止的主导地位。然而，这些手表的核心和灵魂的音叉水晶单元已经像技术限制所允许的那样小而便宜。他们如何克服即将发生的危机？他们最终选择的解决方案是实施一项完全未知的技术。第二期“QMEMS故事”将探讨参与QMEMS起源技术开发的工程师的努力。
The year 1974 marked the fifth year since the birth of the world's first quartz watch, the ‘Seiko Quartz Astron 35SQ.’ It was at this time that quartz watches became fully popularized, and production of tuning fork crystal units had to be increased constantly in order to keep up with demand. It was the Quartz Device Division (then Matsushima Industry Co., Ltd.) in Ina, Nagano Prefecture, that was tasked with overseeing the volume production of these devices (see Figure 1). With production and other factors proceeding so smoothly, it seemed as though they could confidently rely on tuning fork crystal units to maintain their core business. Everyone working at the Ina plant was steeped in a deep sense of satisfaction.
On the surface, everything seemed to be going smoothly. However, the engineers working at the forefront of development had no time to rest. Heated arguments were beginning to take place on a daily basis between the engineers at Suwa's Watch Design Division and those at Ina Quartz Device Division. For watch manufacturers, the ability to make devices smaller and more affordable was vital, and they barely had time to pause for breath.

1974年是世界上第一块石英手表'精工石英天文35SQ'诞生以来的第五个年头。正是在这个时候，石英表才全面普及，为了跟上需求，音叉晶体的生产必须不断增加。这是位于长野县伊那的石英器件部门（松岛工业有限公司），负责监督这些设备的批量生产（见图1）。随着生产和其他因素的顺利进行，似乎他们可以放心地依靠音叉晶体单元来维持其核心业务。在伊那工厂工作的每个人都深深感到满意。
表面上，一切似乎都顺利进行。然而，在开发前沿工作的工程师没有时间休息。苏瓦钟表设计部门的工程师和伊那石英设备部门的工程师之间每天都在开始激烈的争论。对于手表制造商而言，制造更小且更便宜的设备的能力至关重要，他们几乎没有时间喘口气。

The Quartz Device Division understood the wishes of the Watch Design Division. But it was simply not possible to make tuning fork crystal units any smaller than they already were. The Watch Design Division, on the other hand, needed the crystal units to be made more compact so that they could move on to their next commercial product line of ladies' watches. They were desperate for the engineers to come up with something.
There was a reason behind the Suwa Watch Design Division's stubborn refusal to back down. It had been 5 years since they had first launched the world's first quartz watch, and competition in the market was becoming increasingly tough, particularly with Hong Kong's sudden rise in manufacturing. It was therefore essential to continue making watches more compact and affordable in order for the company to maintain its dominant position. Accordingly, they began to consider bringing to market a new line of ladies' watches that would be dramatically smaller than existing watches. To achieve this, it was absolutely crucial that they be able to make tuning fork crystal units ? the very heart of these devices - yet smaller again.
However, nothing is without its limitations. ‘Of course, it was possible in theory to make these crystal units even smaller. But that would have caused costs to skyrocket. So the fact remained that in practice, it wasn't really possible to make them any smaller after all.’ This was the true position of the Quartz Device Division. As usual, the inter-divisional arguments were going nowhere.
石英晶振设备部门了解钟表设计部门的愿望。但是，音叉晶体单元的尺寸比以往任何时候都小。另一方面，手表设计部门需要将水晶单元制造得更加紧凑，以便他们能够转向下一代女士手表的商业产品系列。他们迫切需要工程师提出一些建议。
苏瓦株式会社手表设计部门顽固拒绝退缩的原因是有原因的。自从他们首次推出世界上第一块石英表已经有5年了，市场竞争变得越来越艰难，尤其是香港制造业突然兴起。因此，为了使公司保持其主导地位，继续制造更紧凑和更实惠的手表至关重要。因此，他们开始考虑向市场推出一系列女士腕表，这些腕表比现有腕表小得多。要做到这一点，他们能够制造音叉晶体单元是绝对至关重要的？这些设备的核心 - 再次变小。
但是，没有任何限制。“当然，理论上可以使这些晶体单元更小。但这会导致成本大幅攀升。所以事实仍然是，在实践中，毕竟不可能让它们变得更小。这是Quartz器件部门的真正立场。像往常一样，司际争论没有进展。
