Amazon Price: 2900 【Amazing Measurement Accuracy｜Equipped with a 3D sensor with a 0.1% error rate】In rigorous tests conducted by a domestic inspection organization, we have demonstrated high accuracy with a count error rate of only 0.1%. The latest "3D acceleration sensor" simultaneously detects movement in three directions: front and back, left and right, and up and down, allowing for accurate measurement not only on the wrist but also when placed in a pocket or bag. In addition, the "error count prevention function" does not count irregular movements of less than 7 seconds, accurately recording only "pure exercise volume." 【Smartphone Linkage/No Charging Needed｜Simple Design Ready to Use】Solves the problems of "difficult app settings" and "troublesome daily charging." No smartphone linkage or troublesome initial setup is required; you can start using it immediately after opening the box. We have pursued intuitive ease of use that can be completed with button operations. In addition to step counting, we have selected essential functions such as a clock, calendar, alarm, stopwatch, and 50m water resistance. It is also ideal as a gift for senior citizens who are not good with mechanical operations. 【Supervised by a Professional Trainer｜With a Limited Guide to Enhance Effectiveness】Developed jointly by a current personal trainer with over 8 years of coaching experience and a Japanese company. In addition to simply measuring steps, it comes with an original training menu instruction manual that explains "how to walk effectively for health." 【Optimized for Japanese Wrists｜Stress-Free Wearing Comfort】Designed to fit wrist sizes from 15.5cm to 21.5cm, it fits the wrists of both men and women. The lightweight body of only 41.7g and the use of a PU plastic band that is resistant to sweat and water and feels good on the skin ensure comfort even during long hours of wear. With 50m water resistance, there is no need to worry about breakdowns during rainy day walks or sports scenes where you sweat, and it can be washed with water to keep it clean at all times.
