Whether you're a hardcore adventure hiker, an avid runner, or simply looking to count your doctor's recommended 10k steps a day, an Accelerator Series watch fits the bill. Advanced accelerometer technology provides highly accurate readings of a user's speed, distance, and caloric expenditure via a simple wrist watch sensor, eliminating the need for funny looking foot pods or belt clips. Accelerometer technology is 95+% accurate, and much more dependable than traditional pendulum based pedometers. GPS-based running products are very expensive, complicated, and aren't reliable for indoor training or under heavy tree cover. The Accelerator Series is the perfect combination of accurate readings, simplicity of use, and stylish design.

Speed & Distance Pedometer

  • Highly accurate step counter with adjustable sensitivity allows users to tune the sensors to their individual walking style. Doctors everywhere are now recommending 10k steps a day to maintain a healthier lifestyle.
  • All sensors are contained in a simple wrist watch. That means no funny looking mechanical belt clips our funky shoe pods.
  • Get off the beaten path! Free yourself from mileage markers at the track or trail! Pick a new route every day! The Accelerator can automatically distinguish between running and walking, and can calculate your average speed, distance, caloric expenditure, and total exercise time.
  • The Accelerator has a delayed step counter feature that differentiates between ancillary movements and actual steps. This feature provides users with the most accurate results by delaying calculation until it has registered 10 steps in a row to eliminate false step counting.
  • The smart scheduling features allows users to set the pedometer to automatically start/stop counting steps at a predetermined time every day, so you'll never forget to turn it on.

Personal Profile

  • This feature allows users to customize their watch to their specific body type and walking/running style. No matter how fast or slow, tall or short, each user can personally enter their weight, average walking stride, and average running stride in order to ensure accurate results.
  • Hikers can easily account for loaded pack weights.
  • Runners can dial in the stride length to account for varying terrain and/or speed workouts.
  • Quickly adjust weight and stride lengths as conditioning improves.


  • The accelerator series' powerful stopwatch features allow users to record exact results to within 1/100th of a second for up to 50 laps and a total time of 24 hours.
  • Although the watch has several advanced ways of calculating speed and distance, the old-school chronograph still has a place and purpose.

Countdown Timer

  • A simple countdown timer can come in real handy at times. Set it for 10 minutes as a quick reminder. Use it to monitor your running/walking pace and set speed goals. Alternative Time Zone
  • Great for those that travel! Allows users to set and display an alternative time zone along with the current home time display. Never lose track of time no matter where you are.

Daily Alarm Mode

  • We are all creatures of habit in our daily routines. The daily alarm is a great way to set a daily reminder or morning wake up alarm.

How the Technology Works
The underlying technology in the Accelerator Series Watches is an accelerometer sensor. Accelerometers are used to measure acceleration. Originally developed during the Space Race to replace outdated gyroscopes, accelerometers can be found in a diverse range of today's products such as automobile air bags and tilt meters. In the Accelerator watch, a user's movement (acceleration) produces varying degrees of electric current within the sensor, allowing the watch to detect different levels of acceleration, and therefore measure speed and distance.

Another way to explain how an accelerometer sensor works is to envision a marble in a bowl. When the bowl is moved, or accelerated, the marble inside will roll (accelerate) along the bottom and sides of the bowl. When the bowl is accelerated faster, the marble will move a greater distance up the sides. The accelerometer sensor in the Accelerator Series watch acts like an electronic marble in a bowl. With every step forward, the wearer of the watch (bowl) is accelerating forward. By measuring the acceleration of the "marble", the software inside the watch can then calculate the wearer's speed and distance.

The Competition
There are really only a few different ways to calculate the speed and distance of human-powered, on-foot travel. The first was basic math, next came the mechanical pedometer, followed by satellite tracking GPS years later. Mechanical pedometers are cheap and abundant, but also highly unreliable. They operate on a simply pendulum clicker that relies on the walker's hip movement to count steps. Unfortunately, mechanical pedometers end up counting a lot of non-walking movements and assume that walkers are making consistent and repetitive steps.

GPS technology is impressive, but also expensive, complex, and not always ideal for outdoor activities or indoor training. Satellite signals can be lost in heavily forested areas, indoors, or behind large buildings and receiving signals eats up batteries. When a good signal can be found, often the device does not receive info often enough to account for twisty backcountry trails.

The Future
The Tech 4 O Accelerator Series fills the void between old mechanical pedometers and the overkill of GPS. A simple, yet versatile, wrist-watch design can provide extremely accurate speed and distance data in all conditions.

  • Nice watch
    I havent used it to track my miles yet, which I bought it for. The instructions are long and it will take a while to figure out how to do it correctly. Overall nice watch and will work good for tracking my time when i run....more info
  • Great watch!
    This is a great watch! I love the pedometer feature and it is the most accurate I have ever used. I would definitely recommend this product....more info
  • Tech4O Watch.....Great Watch
    I recently purchased the Tech4O watch. This is a great fitness tool. I love the watch. You need to be somewhat technical to figure out how to use the watch, it comes with a lot of instructions. I love the pedometer functions and tracking that this watch can do. I am just starting out on my fitness plan and this watch has helped me to track my progress on the number of steps I have done and encourages me to do more....more info
  • too complicated
    this watch was too complicated to program. I wanted a watch that had the pedometer in it so I wouldnt have to have it hanging on my waist but this is so complicated I cant figure it out. wish I never bought it...more info
  • Awesome Buy!
    One of the best tihings I've ever purchased! I love top have the ability to keep track of the miles I run and the calories I burn. Because I always suspected that the stats on the treadmill were off. Just wish it came in more colors. I'm not really a girlie girl so wearing a pink watch everyday would be a bit much....more info
  • Great watch; bad instructions
    I love the watch, but the instructions that came with it are TERRIBLE! I am still trying to figure out all of the different things this watch can do. I have figured out the pedometer, and it works well for me. I just wish the instructions were easier to understand....more info
  • Good for the price
    Got this for my wife and she likes it well enough but did say that she wished I would have got the other one with more functions. Thats all I know...more info
  • Tech 4 0
    Gave this watch to my wife, she loves the style and basic functions. The watch does take some time to configure, and is not user friendly at all. If you have the time and the techy knowledge this is a good watch. None the less its very sporty and stylish for a womans watch. ...more info
  • It's a great pedometer; better than any waist one I've used
    I bought this after being very frustrated with the waist ones that I'd used. I could never get it in the right place over my hip bone, and due to my particular body shape, I found it poked me when I did have it in the right place.

    I then went looking for a wrist pedometer once I'd learned that there was such a thing. I've used it for a few weeks now, and I cannot attest to it marking distance when running or for longevity, but as a pedometer, it's great. I'm slowly working up to 10,000 steps a day ( I get it some days) , and it's helpful to just be able to wear it as a watch; no thinking ahead. I also find that having it visible motivates me to move away from my desk several times a day and walk around-getting more steps in, and making me feel more energentic.

    I'm glad that it's so accurate. Nothing more frustrating than having to stop and see where you are with the waist one, only to find that a mile into your walk, you've not gotten it in the right spot, and nothing is counted. This one goes on with the touch of a button, and you just have to glance at your wrist to see how far you've gone. It's really helped motivate me to do more-and that's saying a lot. I hate to exercise. ...more info
  • Walk off the Weight
    This thing is great! I joined weight watchers a while back. The watch helps me keep track of my steps easily and is super easy to use. I don't have to think about it I just turn on and check how far I have walked at the end of the day. I have taken off 12 pounds so far. Thanks ACCELERATOR .....You are effortless!!!!

  • as advertised
    The watch performs as advertised - easy to set, get calibrated,an excellent product and price - I would recommend highly ...more info
  • didn't last a year
    The pedometer is the reason I bought this watch. Accuracy was OK. to be expected for the price without GPS. Easy to read numbers. Complaints are the face scratched very easily and made it hard to read the numbers. The face plate popped off after 4 months and had to glued several times. Very complicated to figure out. Last but not least the band was awful. The color does stay pretty for long after you sweat it turns peach on the band which looks terrible with the pink face. It always looked dirty.(bleach did not help)...more info
  • Watch has been returned
    I bought the watch as a Christmas gift for my mom who wears a pedometer all the time to make sure she is getting in all her steps. I thought this would be a great way to count her steps and have the time all in one stylish watch. She tried it for a couple of days but was never able to get it to count her steps accurately. She had a few people look at it with no success. The watch is great for the runner who wants to see how far they ran, but not for the everyday person who just wants to count steps. ...more info
  • So helpful!
    This watch takes a bit of time to figure out, since there are so many functions and only 3 buttons that really control things (4th button is for the light), but once you get the hang of it, it is just perfect! The look and feel is really great, since it's not too bulky, looks feminine, and fits comfortably on your wrist. The numbers on the display are large enough to read with ease, even while running. Overall, I have to say this watch is highly useful for those who are avid runners, and seek a way to track their distance, speed, and time. ...more info
  • Pretty but frustrating
    I was really happy to find more of a feminine looking pedometer watch in this. The thinner band and pink color is nice. However, I mainly purchased this to count my daily steps, see how many miles I "stepped" and how many calories I burned. The frustrating feature is that it constantly shuts itself off from counting the steps if you are not moving for a certain period of time. You have to always be thinking of checking it and turning it back on. It's not working for me in that respect. I am unable to see a full day's computation of steps. I had another watch pedometer that did that beautifully except it was big and clunky and only came in black. If this brand could change this feature, it would be perfect for my purposes.

  • I hate this product
    I hate this pedometer. Although I consider myself technically literate, I am at a loss to follow the--oh so many--divergent paths setting this up requires. I have bought several pedometers in Italy, and I have understood instructions written in Italian, French and broken English. I have always been able to follow the underlying logic in whatever language, but this one defies any path of programming a reasonable person would be expected to know. I can easier track my daily steps by counting them as I walk. And forget ever finding the distance covered or calories spent. Sometimes I accidentally stumble across the distance if I push just the right buttons in the right sequence, and when the moon is aligned with Jupiter, and the dog howls at night.

    Yes, I have been to the online "help" demonstration. It is even less clear than the multi-folded, needlessly complicated instruction booklet that came with this useless piece of plastic. Beware when the instruction booklet is larger than an atlas and then tells you to go online for help. This means that the manufacturer knows the thing is needlessly complicated.

    If you want to spend more time figuring these instructions out than actually working out, then this product is for you. Also, I agree with the previous comment about the girlie pink band. It just reminds me how stupid the whole marketing plan for this product is (let's make something so complicated that only a programmer could program it and then design it with a Pepto-Bismol pink band). Yeah, that's the ticket.

    Not only have I totally wasted my money, I have also wasted several hours trying to figure out. ...more info
  • Works great!
    I have been using this watch for about 1 month. The distance measurement function is surprisingly accurate. As other reviewers have mentioned, you must take the time to read the instructions and do the stride length measurement. I have only two gripes - the size of the readout is small, particularly the upper numbers (I used to use a Nike running watch that had enormous numbers, so it's a hard transition). For that reason I gave it 4 stars instead of 5. The second gripe is probably a RTFM issue, but the pedometer randomly turns itself off when you're stationary for a while (at least it seems that way to me). Basically, the thing works as advertised.

  • Tech 4 O Accelerator Women's Running Watch
    This is a pretty watch to put on your arm while walking. However, I bought it in April to use while I walked for medical reasons to know how far I am walking. I have yet been able to figure out how to use it. My husband finally got the clock set on it, but I can't figure out how to get to where I want it to start counting my steps and everything on the watch is either too small or to washed out to read to know what buttons you are pushing. For me, this was a waste of my money....more info
  • Tech 4 O Accelerator Women's Running Watch
    Awesome watch. Not as difficult to set up as expected. Switches very easily between distance, timer, calories, etc. Very pleased!!!...more info
  • Very nice pedometer
    This pedometer works very well, and really helps to keep you motivated. The instructions that come with it are really hard to understand, but once you figure out how to use the watch, it's pretty easy to use. The colors are a little brighter than what you see in the picture. It would be nice if there were more color choices. Overall, I am happy with this product, and I recommend it. ...more info
  • Walking Great / Running Not
    I got this watch to help me decrease my times for 5k, and it defiantly not 95% accurate. I run ~10-11 minute mile; yet, both on the treadmill and outside, this watch was reading ~7.5 to 8 minute mile. Distance was also off by +20%, when running.

    Speed and distance ~98% accurate for walking 15 min/mile.
