ULTRAK 420 Waterproof Stopwatch – IP67 Cumulative Split Timer with Extra-Large Display, 24-Hour Range

The ULTRAK 420 is the keep-it-simple waterproof stopwatch: cumulative split timing, an extra-large display, and a chronograph that measures up to 24 hours, sealed in an IP67 waterproof case. No menus to fight with gloves on, no features between you and the clock — just a tough timer for all-day field trials, hunt tests, long training days and hound work, where the event runs from before sunrise to after the last dog is put up.

IP67 Waterproof with an Extra-Large Display

Rain, marsh spray, wet hands and a stopwatch dropped in the grass: the 420's IP67 waterproof rating means weather is not a reason to put the timer away. The extra-large display reads fast at arm's length — while you are holding a lead, watching a dog work, or judging a run — so the number you need is the number you see, first glance, every time.

Cumulative Split Timing to 1/100 Second, up to 24 Hours

The 420 displays cumulative splits at 1/100-second resolution — shown as minutes, seconds and hundredths up to 39 minutes 59.99 seconds, then switching to hours, minutes and seconds for the long haul, with a full range of up to 24 hours. Time a whole field trial day, a hunt test, a long conditioning session or a hound event on a single run of the clock, taking cumulative splits as each dog or brace finishes.

Time, Calendar, Alarm and Chime — Ready Every Morning

Between events, the 420 works as your daily clock with time and calendar display and an alarm and chime to start the day on schedule. Power comes from a lithium CR2032 battery, the included lanyard keeps the timer on you instead of in the truck, and ULTRAK backs it all with a five-year warranty.
