grand seiko original “ready / start mode,” according to the
After a small table top since the complexity of function alarms with spring drive movement successful, has to verify the original design in line with the spring drive can be equipped with the objective of many functional components. Seiko Seiko in 2007 to redesign a new movement of time stopwatch, stopwatch timer can be operated at the same time, gmt time and show the two power stored energy is available on the market features a rare combination of time and the first time by the two-stage operation model, to ensure the accuracy of timing. In addition, the first time in the 1960s published by seiko vertical clutch and column wheel lead time devices, improve time-sensitivity and stability operations. To enable accurate stopwatch button operation, grand seiko “spring drive chronograph” also created “ready / start mode” button, operating time button, the button to the first paragraph may become a “standby” status, start time to ensure that the second hand on time and at the same time button in order to avoid breaching the rules, the design of a spin-in button to lock the structure. Table paragraph with the “vertical-off” structure, in the Seiko seiko in 1969 launched the “61 series speed timer” and become the world’s first automated use of this structure on the timing chain stopwatch, seiko Seiko inherited the pursuit of reliable, practical tradition, and excellent columnar guide pulley system, continues to this day is still accurate, high-quality synonymous.
Spin-in button to lock device so that to increase water depth of 200 meters.
To achieve high-quality, practical and durable high-level time stopwatch
Although the same table with the mechanical spring-driven, but by virtue of the governor spring drive mechanism – the “three to the whole law” is controlled stopwatch timer can be the same paragraph with the general form, the average accuracy of up to ± 15 seconds on poor (equivalent to deteriorate ± 1 sec). grand seiko since its inception in 1960, in terms of time accuracy, recognition, the manipulation of nature, durability and so continue to look for excellence, have demonstrated the function of watch. In addition to the quality of the ultimate, it is a long-term, practical day-to-day wear the High Table. In both the spring drive precision quartz movement, based on fine mechanical watches so that the grinding process at the same time have a grand seiko “mechanical style” and “precision quartz” double feature. In addition to the functions of time stopwatch, the grand seiko always unique simple design with an emphasis on style is easy to operate business. The use of the 5 classic grand seiko surface cutting, sword-based indicators, as well as 5 of the time scale cutting surface to ensure that the form shall identify the best degree. The length of time the central pointer and scale is also very particular about configuration to achieve the best visual interpretation of the stopwatch timer. Calendar can be linked with the adjustment of the “independent calibration function difference,” the 24-hour indicator at the same time shows the two regions may be time to save power at the same time display configuration utility function, is very suitable for business professionals.
