ACCUSPLIT Pro Survivor A601X Stopwatch — Black, 24-Hour Timing, 1/100s Accuracy, 100ft Water-Resistant

The ACCUSPLIT Pro Survivor A601X is a rugged, precise handheld stopwatch built for long service life, 24-hour timing, and easy reading under tough conditions.

Designed for coaches, referees, outdoor trainers and event timers, the A601X combines a durable ergonomic "X" case with a high-contrast Magnum XL display, long-life lithium battery, and robust internal electronics. It runs on ACCUSPLIT's WOS 2.5 operating system, records cumulative splits (no lap storage), and offers a 24-hour timing range with 1/100-second resolution. Built to stand up to shock and water exposure, this model aims to be a dependable, simple timing tool for repeated daily use.

How accurate and responsive is the A601X for precise timing?

The A601X uses a quartz oscillator and electronics that sample switch closure every 1/256th of a second, delivering times to the nearest 1/100 second. Factory calibration yields actual accuracy around 0.04 seconds per hour over the first year, with long-term accuracy primarily affected only by shock and quartz aging. For short events and cumulative split timing, this provides repeatable, reliable results.

• 1/100-second resolution with 24-hour range.
• Switch sampling at 1/256th-second for tight rounding to nearest 1/100.
• Calibrated to ~0.04 sec/hour accuracy in the first 12 months.

What makes the construction durable for field or pool use?

The Pro Survivor A601X sits inside ACCUSPLIT's distinctive "X" case, molded for ergonomic handling and impact resistance. Buttons are rated for million-cycle operation with no-fail performance, and the housing is water resistant to 100 feet. The result is a stopwatch that tolerates drops, regular outdoor use, and incidental water exposure without losing functionality.

• Ergonomic "X" case that resists shock and fits comfortably in hand.
• Water resistance to 100 feet suitable for wet conditions and rain.
• Million-cycle mechanical switches designed for consistent, long-term use.

How long will the battery last and what power does it use?

This model ships with a CR2032 lithium cell designed to last up to five years under normal use. The long-life battery reduces maintenance and downtime for frequent timers and event organizers. Battery replacement is straightforward when required, and the stopwatch is available in two similar voltage versions (3.0V/3.01V) depending on production batch.

• Installed 5-year CR2032 lithium battery for extended service life.
• Low-power electronics and efficient display to maximize runtime.
• Easy battery replacement keeps the unit serviceable for years.

What display and timing features help in real-world use?

The Magnum XL display presents large digits for quick reading at a glance, reducing errors during fast-paced events. The unit supports cumulative split timing (records splits that add across the session) and offers time-of-day, month, and date functions alongside stopwatch capabilities. There are no lap memory features—this stopwatch focuses on simplicity and immediate readout.

• Large, high-contrast digits for rapid visibility.
• Cumulative splits only (no lap memory), plus 12/24-hour time, month and date.
• Simple control layout with proven no-beep mechanical switches.

Who is this for? The ACCUSPLIT Pro Survivor A601X suits coaches, officials, outdoor instructors, lifeguards, event volunteers and anyone needing a rugged, easy-to-read stopwatch with long battery life and reliable split timing. If you want a no-nonsense timing tool built for frequent use, splash exposure and years of service, the A601X is engineered to meet those needs without added complexity.
