To determine what would be required and produce the systems necessary for the Games they examined the various timing methods and equipment used for international events at that time. Hattori-san did not accept this response and over the next few weeks it became clear that he could not be swayed in his plans. Inoue-san stated that this would not be possible as the games were just four years away and Seiko would have to build complete timing systems from scratch as they did not currently have suitable experience in sports timing. Upon returning to Japan Inoue-san was visited by Hattori-san who told him that he intended for Seiko to be the timer of the Tokyo Olympics. Inoue-san did not go to Rome but instead tasked one of his staff to attend. Hattori-san sent a telegram to Saburou Inoue the Watch Design Section Manager at Daini-Seikosha, who was travelling in Switzerland for business, instructing him to visit the Rome Olympics to observe how the timekeeping was conducted. President 1946-74) decided that Seiko should handle the official timing duties for the Tokyo Olympics. As soon as this announcement was made Shoji Hattori (Seiko Corp. On May 26th 1959 it was announced that Tokyo would host the 1964 Olympics, the first time the Games were to be held in Asia. The history behind the development of these stopwatches is interesting and is directly tied to the awarding of Seiko the role of official timer for the 1964 Tokyo Olympics. The stopwatch is wound via the central crown. To reset the hands the crown is depressed. To stop the chronograph the right button is depressed. Once the split time has been noted the left button can be pressed again allowing the paused second hand to catch up with the moving hand. When the left pusher is activated, one of the seconds hands is stopped allowing the elapsed time to be recorded, while the other seconds hand continues allowing the timekeeping to be maintained. To start the watch the right pusher is depressed, the split second function is activated by pressing the left button during operation. The stopwatch has three pushers and is operated as follows. One rotation of the seconds hands around the dial, indicates an elapsed time of sixty seconds. A sub-dial at 12 o’clock indicates the elapsed minutes and the outer dial markings are divided into 1/5th of a second increments. The stopwatch movement operates at 2.5Hz (18,000 bph). The 89ST 010 can measure up to 30 minutes duration in divisions of 1/5th of a second and has a split second function.
