Key Features of CASIO HS-70W

1. High-Precision 1/1000-Second Measurement

The CASIO HS-70W can measure time in 1/1000-second increments, making it suitable for applications where highly accurate timing is important.

The stopwatch provides measurement accuracy of approximately 99.9988% at normal temperature.

2. Multiple Timing Modes

The HS-70W supports several useful measurement functions:

• Elapsed time
• Lap time
• Split time
• 1st–100th place timing
• Lap counter up to 99

The total elapsed-time and split-time measurement capacity extends to 9 hours 59 minutes 59.999 seconds, while lap time can be measured up to 59 minutes 59.999 seconds.

3. Large Memory Capacity

One of the major advantages of the HS-70W is its built-in memory.
