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.

Customer Reviews:

  • Great watch!
    I love this watch. So much better than wearing a pedometer. The only bad thing I can think of to say about it is the face is a little too big for my wrist, but I am a petite person. I wear it whenever I run or hike and after adjusting the sensitivity it works perfectly....more info
  • Exercise Enthusiast With So Little Time
    I would have rated the product 5 stars as far as quality, but the reviews that I read berfore ordering were correct - the instructions were complex for setting up the device. As one comfortable with computers and am not intimadated by things such as this I took a chance. I could have figured the instructions out if I had enough time, but it just was not worth it to me - I would rather be out walking or hiking than trying to figure it out so I returned it....more info
  • Can't believe it works this well!
    Excellent alternative to more expensive GPS's and old-fashioned 'clickety-clack' pedometers. I can vouch for the 95% accuracy. I don't like the auto-resetting function of the pedometer but maybe I just haven't figured out how to use it properly. I do like how it records data by date. Prior to use, you do need some patience and a 9-yr old child to help teach and motivate you to figure out most functions. I would ask Tech4O to come up with a model that has a better crystal. Mine is pretty scratched up and I might pay $50 more for one that's more scratch-resistant....more info
  • Great Exercise Tool!
    This watch has made working out easier and more enjoyable. It takes the guesswork out of estimating mileage for running and walking. I find myself going farther than ever. I use it when I walk the dog, walk at work, and run. The watch looked large in the picture, and I was worried about it being too big for a petite wrist, but it was no larger than my other athletic watch. The watch was easy to set up once you understand the map of the features that comes with it. I had to adjust the stride length a couple times, but once I got that down, I was ready to go!...more info
  • Nice but Confusing product
    The watch looked nice but it is very confusing to figure out how to set it up in order for it to calculate the distance traveled. ...more info
  • great gift for moms
    my wife has used this watch now for a month AND ABOUT 70 MILES. i got it for her (or i should say our children got it for her) on mother's day. we set out immediately to use it on our walks. after making adjustments with it a few times and setting up the correct sensitivity(hers is 3)it works every time within the written 5% accuracy. in fact we once used it and found that it was about 10% off and thought it was broken, but after rolling up her sweatshirt sleeve, we found it to be within the 5% again. i am not sure whether it times out or not quite frankly since we use it for long walks ..but it is great for someone who wants to know how much they are walking on a daily basis INSIDE AND OUT. i use a gps unit and she has regularly been about 2-3% off ...BUT I CANNOT USE MINE INSIDE WHICH I THINK GIVES THIS AN EDGE : AS WELL THE COST IS GREAT!!...more info
  • Better than expected, based upon reviews
    I was looking for a watch that I could use while training for a marathon. Some days I need to run/walk for a certain period of time, while other days I need to run/walk a certain distance. This watch does both. If you take the small amount of time to calibrate it to your stride length (very easy to do, and the watch comes with instructions on how to do so), the watch is very accurate. I went on my first run/walk this morning and the distance the watch measured corresponded with the distance the route was. I have also counted steps in my head while walking and running and the pedometer was accurate (exact match).

    Some reviews have complained about the pedometer automatically shutting off after no movement for a while. Perhaps they didn't realize you can customize the "sleep time" for the pedometer: 1 minute up to 240 minutes. If you get up and walk at least once every 4 hours, the pedometer shouldn't shut off all day.

    While the watch is more complicated than a standard digital watch, I didn't find it exacerbatingly so. There is an online tutorial at the tech4o website (mentioned in the instructions that came with the watch) that I found very helpful. It walks you through every function and menu. I also managed to figure out how to work most of the functions by simply pressing buttons and playing around with it.

    I would definitely recommend this to anyone who needs to count steps, measure distances, etc. I find it both accurate and easy to use once you know how to use it....more info
  • Just received this watch....
    So far, it is a nice watch, but as another reviewer stated, it is not exactly attractive. Would be nice if it was more streamlined or feminine in appearance. Clunky. Also, the band end comes out of the single loop several times a day, which is something that my husband does not experience with his Timex Ironman watch. That wristband stays put. On the positive, the amenities are really great and i am pleased with the functions offered. The screen is easy to read. ...more info
  • Disappointed with the step counter
    I bought this product hoping it would accumulate the steps/day to motivate me to walk more. It was a bummer to see after I've started the pedometer steps that it would go into sleep mode and that all the steps were not counted. You have to hit start button after sitting down from driving or when at rest to start the count again. It became a bigger nuisance and high maintenance to keep checking if it was not tabulating or not! At night it would chirp intermittedly and hard to follow the instructions to turn that feature off. I'm going for an Omron as recommended by friends instead! ...more info
  • I love this watch!
    I've been wearing this watch now for about 6 months and I love it! Don't think of it as a watch as much as a small computer on your wrist. The instruction manual isn't very user friendly, but the watch is easy to figure out if you just play with it. Bottom right button turns on the top right button to start. Viola! I wear this watch when we go on vacation or hiking to know how exactly many miles we've walked. I also use this to exercise outside...its great for keeping track of your steps, milage, and total exercise time. It can tell if you are walking or running (unlike a pedometer) so this is great for exercising. Highly recommended....more info
  • Nice for Price
    This watch has alot of features. I use it mostly for the pedometer. Seems to work fine so far. My only problem is the watchband is so stiff, it is slightly uncomfortable. Overall I am satisfied....more info
  • Accelerator Women's Hiker Watch
    Attractive. Lightweight. Multiple functions.
    Too bad I couldn't figure them out. Which mode to push,when, how many seconds, etc. etc. etc.
    IF you want something quick and easy, this is not the product.
    As it stands now, I am not using it. I'll stick with those cheaper models.
    A higher I.Q. than mine is required here!...more info
  • Fatal Flaw
    The product description twice mentions the "doctor recommended" program of walking 10,000 steps per day, which is why I bought this watch/pedometer. But it doesn't accumulate your steps throughout the day. If you sit down for 30 minutes, the pedometer goes into sleep mode and you have to re-start it to continue counting. If you forget after driving or working at your computer, you miss the steps you take, which pretty much blows your program. All the watches in the Accelerator line are virtually identical. They're just packaged differently. Furthermore, if that flaw doesn't bother you, the directions for this watch are impossible to understand. I had to call customer service three times and even they had to ask for help to figure it out. They faxed me a simplified set of directions, but that was only slightly more help. ...more info
  • Great Watch
    You will love this watch if you know how to read instruction manuals. If you cannot read an instruction manual I doubt you will find the watch of much use. Being that I CAN read instruction manuals I am very pleased with this watch. It helps me get my 10,000 steps per day, everyday. I do agree it would be nice if the pedometer didn't time out but it does. I just simply remember to check it often- which has become a habit for me. It sure beats all those clip on pedometers- which aren't very accurate and break easily. I was going tnrough about 1 of those every 6 weeks! I Love my Tech4O if only they could make them a bit more fashionable!...more info
  • Tech 40 is super!
    I ordered this watch for my daughter who was running in the Kentucky Derby Festival Mini Marthon for the very first time. She loves it. Found it easy to program and very efficient. Best of all, it arrived two days after I ordered it. Wonderful item and service....more info
