The 7 Best Stopwatch Picks, Reviewed
Every best stopwatch on this list is a digital, handheld sports timer from an established timing brand. If you prefer a wind-up dial, see our separate guide to the best mechanical stopwatch models instead. Also, we left out phone apps, since a dedicated button is faster and more reliable in the field.
Best Overall
1. ACCUSPLIT Pro Survivor A601X
Best for: Coaches, PE teachers and athletes who want one tough, easy-to-read stopwatch that just works.
The Pro Survivor A601X is the best stopwatch for most people because it gets the basics right and adds nothing that slows you down. First, its Magnum XL digits are large enough to read at arm length on a sunny track. In addition, it times in 1/100 second steps up to 40 minutes, and then it keeps counting across a 24-hour range in coarser steps.
Next, it handles cumulative split and event timing, plus 1st and 2nd fast finish, so you can catch the top two places in a heat. Also, ACCUSPLIT says the case is rugged, shock resistant and water resistant. Finally, the included CR2032 cell is rated for about 5 years, and a breakaway safety lanyard comes in the box.
- Resolution: 1/100 s for intervals up to 40 minutes; 24-hour timing range
- Cumulative split, event timing and 1st/2nd fast finish
- Magnum XL display digits; time and date functions
- Water resistant and shock resistant case (no depth rating stated)
- CR2032 battery included, about 5-year battery life; 5-year limited warranty
Pros
- Very large, clear digits
- Long battery life and warranty
- Simple controls that new users learn fast
Cons
- No recall memory for stored laps
- No backlight for dark gyms or night runs
- Water resistant only, so not built for pool submersion
Skip it if: you need to store and review dozens of laps after a race.
Best for Lap Memory
2. Ultrak 495
Best for: Coaches who time repeats and want to review every split after the set.
The Ultrak 495 is a coaching tool first. First, it stores 100 recallable split memories, and you can recall them while the watch is still running. Moreover, you can record new splits while you are in recall mode, so a busy interval session never forces you to stop the clock.
Its large three-row display shows the split on top, and the bottom row can show running event time or running lap time. As a result, you see both the lap and the total at a glance. In addition, a stroke and frequency function counts tempo for swimmers and rowers. Also, the 495 measures up to ten hours, which covers a marathon or a long meet session.
- Memory: 100 recallable dual split memories
- Three-row display; bottom row shows event or lap time
- Timing range up to 10 hours
- Stroke/frequency function; time and calendar
- Water resistant; lithium battery; 5-year warranty
Pros
- Recall and new splits while running
- Lap and total time on one screen
- Stroke rate mode for swim and row
Cons
- More buttons to learn than a basic timer
- Only 100 memories, versus 500 on the 496
- No backlight
Skip it if: you only time one event at a time and never look back at splits.
Best Budget
3. MARATHON Adanac 3000
Best for: Teams, referees and parents who want a dependable timer without paying for memory features.
The Adanac 3000 is the best stopwatch for a small budget if you still want a known brand. To begin with, MARATHON calls it a commercial-grade unit, and it reads to 1/100 second for the first 30 minutes. After that, it switches to 1 second steps and keeps running up to 24 hours.
It also has a split mode. In this mode, therefore, the display freezes on the split while the total keeps running in the background. In addition, the separate start/stop and reset buttons make it hard to clear a time by accident. Finally, the case is water, dust and shock resistant, and a 46 inch lanyard is included.
- Resolution: 1/100 s for 30 minutes, then 1 s up to 24 hours
- Single and split timing with frozen split display
- Separate start/stop and reset buttons
- Time, calendar and alarm
- Water, dust and shock resistant; 46 in (117 cm) lanyard
Pros
- Low cost for a branded stopwatch
- Hard to reset by mistake
- Bright color options help you find it in a bag
Cons
- No lap memory
- Resolution drops to 1 s after 30 minutes
- No backlight
Skip it if: you time long events and need 1/100 s past the 30 minute mark.
Best Pro
4. Ultrak 496
Best for: Serious coaches and meet officials who time heat after heat and want every split saved by event.
The Ultrak 496 is the big-meet version of the 495. First, it stores up to 500 dual split memories. In addition, it offers two memory modes. Single memory clears the last event when a new one starts, while block memory keeps several events apart until you erase them. As a result, you can time a full session and sort it later.
It also adds a race control, or target, timer. For example, you enter a goal time, and the watch compares each new reading against it. Moreover, recall works while the timer runs, and you can take splits in recall mode. Like the 495, it has a large three-row display, a stroke and frequency mode and a range of up to ten hours.
- Memory: up to 500 dual split memories; single or block memory
- Race control/target timer to compare against a goal time
- Large three-row display; bottom row shows event or lap time
- Timing range up to 10 hours; stroke/frequency mode
- Water resistant; lithium battery; 5-year warranty
Pros
- Huge 500-split memory
- Block memory keeps events apart
- Target timer for pace work
Cons
- Costs more than the 495
- Many modes to learn
- No backlight
Skip it if: you time one athlete at a time and never review splits.
Best Water Rating
5. ACCUSPLIT AX725
Best for: Coaches and officials who time in rain, spray or splash zones.
The AX725 is the stopwatch we would grab for a rainy meet or a splash zone. Unlike most sports timers, ACCUSPLIT rates it water resistant to 30 m (100 ft). In addition, a dual line display shows lap and cumulative time at once, so you read both splits in one glance.
Next, it stores 16 dual split memories, and recall runs last in, first out. Also, twin-button operation works with either hand, and one button handles a rapid split and reset. Moreover, ACCUSPLIT says the switches are rated for over one million cycles. Finally, the CR2032 battery is rated for 5 years, with a 5-year warranty.
- Water resistant to 30 m (100 ft); shock resistant case
- Memory: 16 dual split (lap and cumulative), LIFO recall
- Dual line LCD; 10 hour timing range
- 1, 2 fast finish; event timing; split counter
- CR2032 battery, 5-year life; 5-year warranty
Pros
- Real depth rating for pool decks
- Lap and total on two lines
- Switches rated for a million presses
Cons
- Only 16 memories
- Fast finish covers two places only
- No backlight
Skip it if: you need to save a full meet of splits.
Best Backlit
6. MARATHON Adanac 8000
Best for: Anyone who times in dim gyms, at dawn practice or at evening games.
Most sports stopwatches skip a light. However, the Adanac 8000 adds an orange backlight that stays on for five seconds, which helps at a dim indoor meet. In addition, its comfort-grip buttons give tactile feedback, so you feel each press with cold hands or gloves.
Timing matches its little brother. Thus, it reads to 1/100 second for the first 30 minutes and then 1 second after that. Also, split mode freezes the split while total time runs. In addition, it adds time, calendar and alarm modes, and the case is water, dust and shock resistant. Finally, a 40 inch safety breakaway lanyard is included.
- Resolution: 1/100 s for 30 minutes, then 1 s
- Single and split-event timing
- Orange backlight, five seconds per press
- Tactile comfort-grip buttons; time, calendar and alarm
- Water, dust and shock resistant; 40 in (102 cm) breakaway lanyard
Pros
- Backlight for low light
- Buttons you can feel
- Breakaway lanyard for safety
Cons
- No lap memory
- Coarser 1 s steps after 30 minutes
- Costs more than the Adanac 3000
Skip it if: you only time outdoors in daylight and want the lowest cost.
Best for Swim Coaches
7. FINIS 3x300M
Best for: Swim coaches who want a pool-deck stopwatch from a swim brand.
FINIS is a swim training brand, and the 3x300M is built for the pool deck. Its listing describes a waterproof stopwatch with a 300 split memory and a stroke rate mode. Therefore, it covers the two jobs a swim coach does most: saving splits for a whole set and checking tempo.
Stroke rate matters in swimming because pace depends on both tempo and distance per stroke. So a coach can read strokes per minute without doing the math. In addition, the easy-read display helps when glare bounces off the water. However, we could not open a full spec sheet, so we only list what FINIS states in its listing.
- Waterproof design for pool-deck use
- Memory: 300 splits
- Stroke rate mode
- Easy-read display
Pros
- Made by a swim brand for swim coaches
- Large 300-split memory
- Stroke rate built in
Cons
- Full specs are hard to find
- Swim focus adds modes runners may not need
- No backlight listed
Skip it if: you coach track or field sports only.
How We Chose the Best Stopwatch Models
We did not run hands-on lab tests. Instead, our picks are research-based. First, we read spec pages from ACCUSPLIT and MARATHON, plus authorized dealer spec pages for Ultrak. For FINIS, we relied on the maker’s listing details. Next, we compared timing range, resolution, memory, display size and build. We also read owner feedback for repeated complaints, such as weak buttons or sudden resets.
In addition, we used the NIST guide Stopwatch and Timer Calibrations (SP 960-12) to judge accuracy claims. Finally, we kept each brand to two models at most, and we dropped unbranded multipacks with no published specs.
- Readability: big digits matter more than extra modes on a sunny field.
- Resolution and range: 1/100 s steps, and how long they last.
- Memory: how many splits it saves and whether you can recall them while running.
- Build: water, dust and shock resistance, plus a lanyard.
- Support: battery life and warranty length.
Stopwatch Resolution vs Accuracy
These two words often get mixed up, so it pays to separate them. First, resolution is the smallest step the display shows. For example, most digital stopwatches show 0.01 s, and a few show 0.001 s. Accuracy, by contrast, is how close the timed interval is to the true interval.
Second, inside nearly every digital stopwatch is a quartz crystal. According to NIST, the most common time base runs at 32,768 Hz, which is 2 to the 15th power. As a result, a frequency error of just 1 Hz adds about 2.64 seconds per day. A typical spec such as plus or minus 5 s per day works out to about 0.0058 percent.
That sounds small, and it is. For instance, a 5 s per day error adds only about 0.035 s to a 10 minute run. Meanwhile, NIST Handbook 105-5 treats a stopwatch as in tolerance at plus or minus 0.02 percent, which is about 2.16 s over 3 hours. So the crystal is rarely the weak link. Your thumb is.
Features That Matter When Choosing a Best Stopwatch
Display size and backlight
A big, high-contrast LCD is the most useful feature on any stopwatch. Also, a backlight helps in dim gyms, and only one of our picks has one. Therefore, think about where you time most often before you pay for extras.
Split vs lap timing
A split is the total time from the start to a point, such as 800 m in a 1,600 m race. A lap, on the other hand, is the time for one section only. Therefore, good coaching stopwatches show both at once. For example, two 400 m laps of 1:58 and 2:02 give an 800 m split of 4:00.
Memory and recall
Memory stores each split so you can read it later. In addition, recall while running lets you check a split without stopping the clock. Similarly, block memory keeps several events apart, which helps at meets. Basic timers, however, have no memory at all.
Countdown, pacer and stroke rate
Countdown timers help with rest intervals and drills. Similarly, a pacer beeps a set rhythm for runners or swimmers. Meanwhile, stroke rate modes calculate strokes per minute from a few taps, which suits swim and row coaching.
Water resistance and power
Most sports stopwatches are water resistant, not waterproof. So rain and sweat are fine, but a dunk in the pool may not be. Most run on a coin cell such as a CR2032, and some last up to 5 years.
Stopwatch Types Compared
| Type | Typical resolution | Memory | Best use |
|---|---|---|---|
| Basic digital | 0.01 s | None | Class, kids, casual timing |
| Split/fast finish digital | 0.01 s | None or a few places | PE, track heats, races |
| Memory digital | 0.01 s (some 0.001 s) | 16 to 500 splits | Coaching, meets, data logging |
| Mechanical (analog) | 0.2 s or 0.1 s | None | No-battery use, tradition |
| Phone app | 0.01 s on screen | App history | Casual use only |
In short, digital wins for most sports use. However, a mechanical stopwatch never needs a battery, and NIST notes that analog models commonly mark 0.2 s steps.
How to Time a Split With Your Stopwatch
Good technique cuts more error than any upgrade. So follow these steps each time you time a race or a rep.
- Reset and check the mode. Clear old times and confirm the display shows the stopwatch, not the clock or countdown.
- Stand where you can see the start. For a gun or whistle start, watch for the smoke or the arm drop, because sound travels slowly over distance.
- Rest your finger on the start button. Press with the pad of your thumb or finger, and keep a light pressure ready.
- Start on the signal. Press as soon as you see the start, not when you hear it.
- Take splits at a fixed mark. Press split as the runner’s torso crosses the line, and line up with the mark to avoid an angle error.
- Stop at the finish and record. Stop on the torso crossing, then write the time down or save it to memory before the next heat.
Time Converter for Splits and Workouts
Stopwatches show minutes and seconds, but plans often use decimals or total seconds. So use this converter to turn seconds into minutes, hours or milliseconds. For pace work, our guide to the 8-minute mile shows how splits turn into speed.
Why 60 seconds and not 100? The answer goes back to Babylon, as our story on why we measure time in 60s explains.
Care and Accuracy Checks for a Stopwatch
A stopwatch needs little care. Still, a few habits keep it reliable for years.
- Check it against a time signal. Start it on a whole minute from time.gov or a NIST radio signal, and then compare after 24 hours. A good unit stays within a few seconds.
- Replace the battery early. A weak cell can dim the display or cause resets, so swap it before a big meet.
- Dry it after rain. Wipe it off and let it air dry, and keep the battery door shut.
- Use the lanyard. A drop onto concrete is a common way to crack a case or a display.
If you need a certificate for a lab or a speed trap, then use a calibration lab. NIST describes direct comparison, totalize and time base methods in its guide.
| Do | Don’t |
|---|---|
| Start on sight of the signal | Start on the sound from far away |
| Line up with the finish line | Time from an angle |
| Treat hand times as good to about 0.1 s | Quote hand times to 0.01 s as if exact |
| Save splits to memory before the next heat | Trust your memory for splits |
Honest Limits of Any Best Stopwatch
Even the best stopwatch is a hand tool. For example, two timers on one race often differ by a tenth or more. Also, hand times tend to be faster than electronic times, since timers react later to the start than to a finish they can see coming.
For records, use fully automatic timing. For training, however, a stopwatch is more than good enough. Consistency matters most, so use the same timer and the same spot each day. That way, trends stay honest even if each time carries a small error. To see how your times compare with the fastest people alive, read how fast a human can run.
Best Stopwatch FAQ
What is the best stopwatch for most people?
The ACCUSPLIT Pro Survivor A601X is the best stopwatch for most people. It has very large digits, 1/100 s timing up to 40 minutes, fast finish for two places and a battery rated for about 5 years.
How accurate is a digital stopwatch?
The quartz time base is very accurate, often within a few seconds per day. For example, 5 s per day is about 0.0058 percent. However, human reaction time adds far more error, often around 0.1 s per press.
Is 1/100 or 1/1000 second resolution better?
For hand timing, 1/100 s is plenty. In fact, your reaction time is much larger than either step. So 1/1000 s mainly helps when an electronic trigger starts and stops the timer.
What is the difference between split and lap time?
A split is the total time from the start to a point in the race. A lap, by contrast, is the time for one section only. For example, laps of 60 s and 62 s give a 2:02 split.
Which best stopwatch has the most memory?
Among our picks, the Ultrak 496 has the most memory, with up to 500 dual split memories. In addition, its block memory keeps several events apart, which helps at big meets.
Can I use a stopwatch in the pool?
Most sports stopwatches are water resistant, not built for diving. So splashes and rain are fine. However, the ACCUSPLIT AX725 is rated to 30 m (100 ft), and FINIS sells the 3x300M as waterproof.
Is a phone stopwatch as good as a real stopwatch?
For casual use, yes. However, a dedicated stopwatch has a physical button, so you do not need to unlock a screen or look down. As a result, it is faster and more consistent in sport.
How do I check if my stopwatch is accurate?
Start it on a whole minute from time.gov, then check it again 24 hours later. Next, divide the difference by 86,400 seconds to get the error as a fraction of a day.
What is the best stopwatch for kids?
For kids, the best stopwatch is a simple one with big digits. The MARATHON Adanac 3000 fits, because it has separate start/stop and reset buttons. So a child is less likely to clear a time by mistake.
Mechanical or digital: which is the best stopwatch type?
Overall, digital is the best stopwatch type for most sports, thanks to 0.01 s steps, splits and memory. On the other hand, a mechanical stopwatch needs no battery, but it usually reads in 0.2 s steps.
Bottom Line: The Best Stopwatch for You
For most coaches, teachers and athletes, the ACCUSPLIT Pro Survivor A601X is the best stopwatch to buy. After all, it is tough, easy to read and simple to run. However, pick the Ultrak 495 or 496 if you need to review splits, and the Adanac 3000 if price comes first.
