Seiko S058 - 100-Lap Memory Stopwatch with LED Light Display

The Seiko S058 delivers the same dual-timer interval control as the S057 with one key upgrade: an LED backlight that illuminates the display for easy reading in low light, early-morning practices, and dim indoor facilities. Built for coaches and officials who need dependable, high-precision timing in any environment, it pairs two countdown timers with a 100-lap memory so full workouts and events are captured and reviewable.
