We developed a high-precision automatic mechanical watch. We aimed at a thin watch which has high automatic winding performance. To achieve these requirements, we adopted a new design of going train in which a barrel and a third wheel don’t overlap. In addition to that we expanded a gap between a third wheel and a balance to reduce viscous resistance of a balance. Furthermore we employed a reverser wheel whose unresponsive angle is small. With those efforts, we achieved a high-precision, thin watch with high automatic winding performance.

  "DURATECT" is a surface hardening technology unique to Citizen Watch Co., Ltd. “SAKURA PINK” was developed as a new color of “DURATECT”. “SAKURA PINK” is composed of a hardened layer, an adhesive layer, and a gold alloy layer on the surface of titanium, and has a color inspired by cherry blossoms. By coating hardened layers, Vickers hardness exceeding 1000 HV and scratch resistance were realized. This product using “DURATECT SAKURA PINK” was released mainly for adult women.

  We introduce our developed Outdoor Watches (S830 Alpinist / S833 LANDTRACER) equipped with Bluetooth Low Energy Wireless Communication Interface, and Smartphone Application for Watch. S830 ALPIST was developed in 2016 and S833 LANDTRACER was developed in 2017. The S830 ALPINIST is the first watch comprises Mountaineering Plan Achievement Rate Function. Watch users can use this watch to get safe climbing by using the climbing plan achievement rate function. The S833 LANDTRACER was developed as the next generation of S830 Alpinist. S833 LANDTRACER is increase the functionally from S830 ALPINIST, equipped powerful function that 3 Dimension Logging for activities of user movement of outdoor. These function of watches possible by using Bluetooth Wireless Communication Interface and Smartphone application.
