The Q&Q HS42 Digital Stopwatch tracks elapsed time using high-frequency quartz oscillation. A 1/100th-second precision rating enables exact data collection for sports or laboratory use. The 53x55mm frame displays hours, minutes, and seconds across a 24-hour range.
Key Features
- 1/100th Second Precision: Internal logic calculates time in 0.01-second increments. Accurate data points support competitive racing results.
- 5 BAR Water Resistance: Hardened casing prevents water ingress at 50-meter pressures. Moisture from rain or heavy sweat won't stop the timer.
- Split Time Measurement: Side buttons trigger intermediate lap recordings while the main clock runs. Monitor multiple runners or timed lab phases simultaneously.
- Japan Quartz Movement: High-frequency oscillation maintains time accuracy over 23-hour cycles. Minimal drift occurs during long-duration timing sessions.
