Casio HS-70W-1DF Digital Stopwatch captures time with 1/1000-second precision. Dual memory banks store 100 laps each for multi-run analysis. Resilient casing blocks road dust and humidity. This iteration increases accuracy tenfold over the HS-3V-1BR and introduces 50-meter water resistance. Battery life also extends to five years from the previous three-year standard.
Key Features
- 1/1000-Second Precision: Chronograph tracks time with a 0.001-second resolution. Detects performance gaps invisible to standard timers.
