Lithium Powered Dual Split Stopwatch

No dimensional or weight data provided; Timing capacity: supports multi-lap timing with dual split storage and real-time memory access; Display: large 3-row LCD showing up to 10 hours, bottom row adaptive to current event or lap time; Functions: stroke/frequency measurement, time and calendar; Build: water-resistant; Power source: lithium battery. The lithium cell ensures stable power delivery across temperature ranges and extended usage — crucial for long-duration events or field use without battery dropouts. Dual split memory enables layered timing analysis, while the 3-row display maintains full context without navigation menus. Stroke mode converts time intervals into measurable output rates, and calendar integration supports scheduling and longitudinal tracking. Used by swimming instructors assessing stroke efficiency across lengths, strength coaches monitoring rest-to-work ratios in supersets, clinical staff timing functional movement sequences, and educators managing timed group activities with overlapping tasks.
