The Fitbit Alta: 

The Fitbit Alta wristband that comes with the watch is made pf a flexible, durable elastomer material that is similar to that used in many sports watches, and it does not contain latex.

The clasp and housing of the watch contain surgical grade stainless steel.

For any leather used in the accessory wristbands and watches, Fitbit uses selected tanneries that provide leathers used widely across the fashion accessory industry, and this leather is carefully selected, colored, and treated to achieve a soft natural grain.

The leather bands are crafted to keep the natural look and feel of leather; it is hand sorted to maintain textural consistency.

It will become more flexible as time goes on while it forms to your wrist. 

There is a tracker on your Fitbit Alta watch that can be connected to your mobile device, such as your cell phone.

Your tracker can vibrate to alert you to calls, texts, or calendar events when it is within range of your mobile device.

To see the notification, turn your wrist towards you (Quick View) or double tap the tracker within one minute in order to turn your watch on.

It is important to do this within one minute because while on some Fitbit watches, the notifications will be saved, they are not saved on the Fitbit Alta and are deleted after one minute has passed.

Similarly to many running watches, the Fitbit Alta has a setting that will encourage you to walk at least 250 steps each and every hour. You'll receive a vibration reminder when there are ten minutes left in the hour if you haven't walked enough steps.

At the end of each hour, a congratulatory message on the hour will let you know that you have met the goal. The Fitbit Alta watch also has a clock face that you can change.

If you choose a clock screen that shows a flower, you can see the flower grow and shrink all depending on your own activity level.

The Fitbit Alta has SmartTrack which will automatically recognize and record select continuous movement activities, such as running and outdoor biking. If you want GPS data for a hike, bike, or run, you can use the MobileRun feature of the Fitbit app.

To see your total steps taken each day, your distance traveled, your calories burned, and your active minutes you can tap the watch face.

The Fitbit Alta’s display is dimmed when it is not in use and will wake up automatically if you turn your wrist towards you (this is known as Quick View) or you can double tap Alta where the display meets the band.

In order to see your Smart Track, which includes any detected exercise, activity levels, sleep patterns, and more, you can simply check your Fitbit dashboard! The Fitbit Alta costs $130.

This watch is also fantastic for triathletes as it is swim-proof as well. Both the bangle and pendant are great for tracking steps and distance you have walked throughout the day in order to hit your goals.

With the connection to a mobile device, you can get notifications to your watch from your phone!

You can get text notifications and call notifications where your watch will not only vibrate, but it will also flash a color coded light on your clock face so you will not miss your notifications.

This amazing watch also sends you notifications ten minutes before the end of each hour if you have not walked at least 250 steps within the hour to ensure that you are moving and not staying sedentary all day.

If you reach the 250 step goals by the end of the hour, your watch will flash a congratulatory message on the clock face! The Fitbit Flex also has an extraordinary battery life of up to FIVE days!

Conclusion: Fitbit Alta Vs. Flex 2​​​​​

Both of these running watches are incredible choices, and they are definitely worth the cost!

For runners who are more casual runners, who run shorter distances, or who are simply wanting to track their activity levels while being able to go straight from work to a work out, I would recommend the Fitbit Flex 2 as it is $30 less expensive and more customizable to an accessory you can where anywhere.

For more serious runners I would recommend the Fitbit Alta. While it is $30 more expensive, it does have specific options for tracking different kinds of activity, and it has a wider wristband with runners’ comfort in mind.

I hope this article has helped you to narrow your search for your new running watch. Happy running everybody!
