Product Description

The Timex Story

Timex Group B.V. is one of the best-known American watch companies. Timex's U.S. headquarters are located in Middlebury Connecticut and it has substantial operations in China, the Philippines and India and full scale sales companies in Canada, the UK, France and Mexico.

The company began in 1854 as Waterbury Clock in Connecticut's Naugatuck Valley, known during the nineteenth century as the "Switzerland of America." Sister company Waterbury Watch manufactured the first inexpensive mechanical pocket watch in 1880. During World War I, Waterbury began making wristwatches, which had only just become popular, and in 1933 it made history by creating the first Mickey Mouse clock under license from Walt Disney, with Mickey's hands pointing the time.

During World War II, Waterbury renamed itself U.S. Time Company. In 1950 the company introduced a wristwatch called the Timex. Over the next three decades, Timex was sold through a series of advertisements which emphasized its durability by putting the watch through "torture tests," such as falling over the Grand Coulee Dam or being strapped to the propeller of an outboard motor, with the slogan "It takes a licking and keeps on ticking." With the help of former Olympic broadcaster, spokesman John Cameron Swayze, sales took off. The company later became Timex Corporation, then Timex Group and, to date, has sold over one billion watches.

The company has remained very competitive and the Timex brand continues its dominance through present day. Its primary market remains the United States and Canada, although the Timex brand is sold worldwide due to its ability to capitalize on its strong brand image and reputation for quality.

One of the most successful and important features available on many Timex watches is the Indiglo backlight system. Indiglo is a brand name of Indiglo Corporation, solely owned by Timex for licensing purposes. Timex electroluminescent lamps, branded Indiglo, were introduced in 1992 in the Ironman watch line. They were an immediate success. The Indiglo lamp uniformly lights the surface of the Timex’s watch dials in a manner that makes the dial read very easily in many different light settings. In some newer watches the Indiglo backlight only lights up the numbers, rather than the entire LCD display, which is achieved by means of a specialized film that inverts the LCD transmissivity.

Today, Timex Group products are manufactured in the Far East and in Switzerland often based on technology that continues to be developed in the United States and in Germany. With a large and varied line of watches, Timex has the style for everyone. From the locker room to the board room, there is a great Timex style time-piece for you.

So far so good ...
After reading a few reviews, I was a little worried about communication between the HRM and the sensor (I'm female, with ... uh ... assets) but the strap fits just fine under the bust and I have yet to experience any communication issues. It definitely helps to moisten the contacts, but as that's advised in the instructions I'd say it should be a given if the HRM doesn't immediately pick up the signal.
Great to have the calorie burn listed in the review function!
I'm not a huge fan of pink so it's nice to see a unisex model that nevertheless doesn't look bulky on my arm. I've always had Timex/Ironman watches anyway so I figured I was safe to stay with the same brand and I was not disappointed.

Basically, if you're looking for a less-pricey-but-still-good HRM with a lot of functions and decent durability, this is your best bet!

This was my first heart rate monitor I've purchased. I enjoy the simplicity of the readings as it offers the average heart rate from a workout as well as an estimate for calories burned. Another good feature can be used during your workout recovery time. The monitor will track how quickly your heart rate recovers from your workout and presents a simple number representing how fit you are.
What I am a little disappointed with is how easily the chest strap looses its connection. For future users, it helps to wet your skin opposed to the individual sensors. This helps but does not resolve the problem completely.

Easy to use. The adjustable band has two plastic oval pads on it that you wet. These are the actual sensors. (You can put on the band first then flip it to wet the sensors then snap on the communicator) The Communicator snaps on the band connecting to the sensors (the thing you see with "TIMEX" on it with Timex on the top.) Pushing on big button on the watch communicates with the communicator to get your heart rate. Best use is for Fitness programs like the P90 series and Insanity to monitor your starting point and progress.

One point before you decide to buy a standalone HRM like this, if you own an iPhone there are programs and sensors that connect to the iPhone by bluetooth that monitor heart rate, and there may be some for Android, so those may be a better solution, I don't know. My guess such systems will kill products like this though their sensors are likely to cost more that this whole product, only the apps may be better. But for my purpose this was all I needed and was low cost.

Hope that helps.

Another reviewer stated that it takes a while for the HRM to start. In my case, about 80% of the time it took even longer, as in NEVER. To get it to start, you had to redo the entire set-up procedure before it would start. After that, it would run smoothly for a minute or two and then stop. Sometimes it would start again on its own only to stop again. Now before you comment and tell me that I must be using the chest strap wrong etc. ect. Please note that this is the third chest strap HRM that I have owned. Each of the other two worked fine until I lost them. Neither of them required anything more than a few seconds to link with the receiver. The Polar was by far the most reliable and was with me through two sets of batteries. I have returned this one for credit and can not recommend something that is defective right out of the box.

I love this watch. I have a treadmill that is supposed to give heart readings, but is never right. Then outside it was impossible to know what my heart rate was. This is lightweight and simple to use. I love the ability to set my high and low heart rate and receive a time at the end of my workout for when I was in the zone. I found I had either been over working, or under working much of the time. With this watch I have been able to stay in my zone and have been losing about 1.5 pds a week with no other changes. I also give a calorie burn, but I don't use it. Very nice and easy to use.

I reviewed many different heart rate monitors before deciding on this one. It did not work. The first time I used it, the heart rate it displayed jumped up and down and then failed to detect any heart rate. I purchases a new battery and it still could not detect a heart rate. I am returning the item.

It is a nice heart rate monitor, void of a lot of bells and whistles. I simply use it to watch my heart rate during workout and tennis, and do not use the other features that are still many. When you turn off the HRM, it turns it into a watch and can go back and forth rather quickly. IIf you are looking for a simple HRM without too many fancy things...this thing is just fine.
