We introduce our newly developed running watch equipped 3-axis accelerometer (ASICS AP01). The watch comprise a three-axis acceleration sensor to count SPM (SPM is an abbreviation for "Step Per Minute"). The detecting circuit to count steps can be small and support not only run but also walk by using three-axis acceleration sensor. Also our newly developed algorithm enables detecting SPM based touchdown impact (landing impact) of the foot and swing of the arm during running/walking with checking the watch display. Furthermore, we were able to achieve the high-precision detection by optimization of detecting condition.
We have developed a new solar digital watch for all kinds of mountaineers, from beginners to experts, young to elderly men and women. With the concept of "enjoy mountaineering in safety", we invited a famous adventurer "Gota Miura" as a development-adviser. This watch have a new function "climbing speed display", which support and enable users to mountaineer in a planned and safe way.
We, CITIZEN WATCH CO., LTD., have been developing analog watches which have Alti-Depth measurements function. In addition to these functions, we developed the analog watch which is capable of measuring not only an altitude but geographic cardinal directions. And we also developed the solar-powered analog watch which has the digital compass function.
We have developed an analog wristwatch featuring new benefits including a solar powered movement, water resistant and refined design that only a metal watch can offer, while enabling smartphone connectivity using Bluetooth Low Energy. This improves the usability of watch filled with functions that need difficult operation and setup.
Industrial products have a production-related problem that it is not easy to accurately reproduce designs which product designers aimed. In watchcases, designs which have complicated patterns or undercuts' shapes correspond to that problem. When those designs are reproduced in products, a conventional machining method will not be satisfied at cost-effective processing time. Moreover, by a conventional press-forging method, it is not able to form a forging-die to reproduce shapes such as undercuts. In this study, we applied a 3D printer that has less limitation of molding shapes than a machining method or a forging method. Specifically, using Lost-wax casting process that used the "Master" molded by a 3D printer, we attempted to form the watchcase including complicated designs and undercut shapes which were not able to reproduce easily by conventional manufacturing processes. By this process, it was verified that the formation of the watchcase which reproduced the original design faithfully was possible.
