→ Certina Ds-2 Precidrive Flyback 1/100 Second Chronograph "Full Set" Swiss Men's Wristwatch. From 2010's. Reference number: C024447 A. The watch is completely original and in very good condition. → The incredible speed and processing power of the PreciDrive means that the split seconds indicator hand hits every single 100th marker during the space of one second. This is a different phenomenon than one might see on a mechanical split second chronograph. In a mechanical watch, the split second hand is effectively free-wheeling at the correct velocity before being suddenly braked when the stop pusher is depressed. In the PreciDrive, the split seconds hand is making one hundred distinct and accurate motions per second; even more impressive, however, is the reset speed of the hands. The advanced micro controller called PowerDrive is capable of shifting the hands up to as many as 200 times a second in either direction, meaning they return to zero almost instantaneously. → The watch is equipped with a quartz Swiss patented high-end ETA movement. All functions work smoothly. → The stainless steel case of the watch appears to be in very good condition. There are hairline scratches on the bracelet due to use. Sapphire crystal glass. The crown, buckle and bracelet are all original. The original gray color dial looks perfect.
