![]() As traditional manufacturing strives to drive digital transformation, advanced and smart manufacturing is the future industry trend. Meanwhile, new blood is scarce in the manufacturing talent pool as young people have low interest in joining and staying in the industry. The challenge has become even more pressing due to the emigration wave, which is causing an outflow of professional and technical talents. The manufacturing technology industry has been facing a significant shortage of industrial talent. In the long run, this helps facilitate the jewellery, watch & clock and optical industries to develop continuously and move forward. Practitioners are also required to equip themselves with robust industry knowledge and emerging skills so as to cultivate a customer-oriented mindset. With the evolution and rapid development of the industries, a consistent supply of manpower is needed. Under the "New Normal", the industries continue exploring new opportunities, producing and introducing fashionable and personalised products, actively engaging online trading platforms as well as strengthening the use of omni-channels for sales and promotion. At the same time, it has also accelerated the “digital transformation” of the industries to sustain business development. The severe coronavirus epidemic and Sino-US trade frictions have dealt a heavy blow to the jewellery, watch and & clock and optical industries. Period during which the timepiece operates with the prescribed performance.Industry’s “New Normal” – Digital Transformation Period between the time the prescribed batteries are installed and the timepiece starts functioning and the time it stops or the electric display cannot be read anymore in normal usage conditions. Test methods are defined in JIS B 7001 - Watches and clocks - Test methods, and requirements and test methods in ISO 1413 - Shock-resistant watches. Shock-resistant watches can resist a free fall from 1 m height to a horizontal wooden hard surface. Protection of the movement (and the motor in particular) against external magnetic fields. The requirements and test methods are defined in JIS B 7024 - Magnetic resistant watches. Type 1 can resist a direct current magnetic field of 4,800 A/m, and type 2 can resist a direct current magnetic field of 16,000 A/m. Resistance against external magnetic fields. Generic term of water resistance for both air and saturation diving. The requirements and test methods are defined in JIS B 7023 - Divers watches and ISO 6425 - Divers watches Annex A. ![]() Protected against immersion in water up to a depth of 200 m when diving using compressed gas mixture (inert gas such as helium with oxygen) as breathing gas. The requirements and test methods are defined in JIS B 7023 - Divers watches and ISO 6425 - Divers watches. Protected against immersion in water up to a depth of 100 m when diving using compressed air as breathing gas. Protected for immersion in water, such as when swimming. The requirements and test methods are defined in JIS B 7021 - Water resistant watches for general use and ISO 2281 - Water-resistant watches. Protected against rain and water drops resulting from sweating or face cleaning in everyday life. ![]() Water resistance means that the timepiece is better protected than devices protected only against water for daily use. Performance of resistance against ingress of water or sweat inside the timepiece case. Usually a watch is adjusted to have the best accuracy stability in these conditions. Temperature range in which a timepiece can maintain stable performance.Īccuracy of a watch when worn at the wrist at least during 8 hours in a day with a temperature between 5 C and 35 C. Temperature range in which a (quartz) timepiece can operate. Method to regulate a timepiece by adjusting the pulse in part of the frequency divider circuit without adjusting the quartz oscillator frequency.Ĭompensation for temperature changes that can affect the accuracy of the timepieces and their functions. It is the difference in unit of time between two rate values or daily rate values measured under the same conditions on different days. Variation over time of the clock rate or daily rate. Measurement value of the clock accuracy over a short period and converted into a daily rate.ĭifference in two clock states measured at a 24-hour interval.ĭifference in two clock states measured at a one-month interval.ĭifference in two clock states measured at a one-year interval. What are the meanings of the characteristics of a timepiece?ĭifference between the displayed time on the timepiece and the standard time.
