The 8-digit calculator can add, subtract, multiply, and divide. A second time zone can be set and retrieved, making it ideal for frequent international calls. For athletes and anyone who wants precise timing: elapsed time, lap time, and finish time are measured with an accuracy of hundredths of a second. The watch has a measurement capacity of up to 24 hours. The daily alarm reminds you of recurring events with an acoustic signal at the set time.
