Casio W-735H Super Illuminator Stopwatch
Sports Officials Timing Watch
When timing matters, sports officials need a watch that is easy to operate, easy to read, and dependable throughout the game. The Casio W-735H Super Illuminator Stopwatch combines a high-resolution stopwatch with countdown timing, vibration alerts, a bright LED backlight, and 100-meter water resistance in a rugged digital sports watch.
Designed for active use, the W-735H is especially useful for basketball referees, football officials, baseball and softball umpires, soccer referees, wrestling officials, coaches, and athletic trainers who need to time specific instances during games, practices, and competitions.
Built for Sports Officials
The W-735H offers timing functions that go beyond a traditional everyday watch. Its 1/100-second stopwatch allows officials to track elapsed time, split times, and first- and second-place finishing times. The stopwatch also includes a 5-second countdown auto-start, providing an additional option when a timed event needs a controlled start.
A 24-hour countdown timer with one-second resolution is useful for situations where officials need to monitor a specific interval rather than simply record elapsed time.
Vibration Alert for Loud Game Environments
One of the standout features of the W-735H is its vibration alert. In a noisy gym, stadium, or field environment, an audible alarm can easily be missed. The vibration function provides a discreet notification and can be used with the daily alarm, hourly time signal, countdown timer, and stopwatch auto-start countdown.
Super Illuminator LED Backlight
The Super Illuminator LED backlight provides bright illumination for viewing the digital display in low-light conditions. The afterglow feature helps keep the display visible briefly after the light is activated, making it practical for evening games, dimly lit gyms, and outdoor events.
Rugged Construction for Active Use
The W-735H features a resin case and resin band designed for everyday sports use. Its 100-meter water resistance adds protection against water exposure during outdoor activities and changing weather conditions.
The watch measures approximately 51.4 × 47.1 × 16.1 mm and weighs approximately 50 grams, providing a substantial digital display while remaining practical to wear during officiating.
