Description

Not a big fan of heart rate straps? The Garmin Forerunner 235 is the first Garmin sports watch with heart rate measurement on the wrist. All you need to do is wear your watch and put on your running shoes, and you'll be all set. Read your heart rate and heart rate zone while you're running, so you can adjust your effort to the right level. The watch features a race time forecast and recovery time. You no longer need to bring out your smartphone to control your music, because you can simply use the controls of the Forerunner 235. You don't have to worry about missing messages or calls either, as these will be displayed on your watch.

Note: an adapter isn't included. Do you want to charge the watch via a socket? If so, order an adapter separately.

fits my personal needs perfectly

  • light and excellent wearing comfort
  • can always be cheaper of course :)

Since the beginning of 2015 I was looking for the right combination between smartwatch and activity tracker. (didn't have to be a watch shape, wristband was fine too). I exercise regularly (fitness) and wanted to actively track my activity, heart rate, sleep and nutritional intake including incoming notifications from my smartphone (calls/texts/whatsapp).

I have tried many different wearables:
Apple Watch
Vivosmart
Fitbit Surge
Fitbit Charge HR
TomTom Cardio + Music
Garmin Forerunner 225

Something was always wrong (no HR pulse sensor, no incoming notifications, awkward dimensions, heart rate that was not accurate, etc). It made me despondent.

Until I tested the Garmin Forerunner 235 HRM.

Even though I think this device is primarily aimed at runners, for my current needs this device is PERFECT and I absolutely recommend it, even if it is a bit pricey.

Perhaps the successor will come with an internal Bluetooth music player? That would be totally brilliant.

I ordered the Garmin Forerunner 235 through Coolblue last Saturday. On Sunday my sports watch was delivered very correctly and quickly. Great service if you ask me!

When opening the packaging, the unique design of the sports watch immediately caught the eye. Unlike many other sports watches, the Garmin Forerunner 235 is a watch that can be worn all day. The design is round, dynamic and above all very young and fresh looking. I have no objection to wearing this sports watch at work. As a result, this sports watch scores quite high in terms of first impressions.

The battery life is high. I wear the sports watch all day long and use the permanent measurement of the heart rate. Despite this, the battery does not lose 5% of its life per day. My negative experience with other sports watches teaches me that this is an excellent performance.

In terms of functionality, I can only give the Garmin Forerunner 235 the maximum of points. You can use it while running, cycling, strength training and even while swimming because it is also completely waterproof. Afterwards you can load all the data in the super clear and user-friendly Garmin Connect app. I rarely saw such a complete sports watch within a realistic budget.

Originally, I was a bit apprehensive about the connectivity of the sports watch. I myself have an iPhone and in the past it has often been found that this causes a problem for connecting the smart watch to the GSM. This is not the case with the Garmin Forerunner 235. The connection works fine and all notifications of calls, text messages and even social media come through perfectly.

Another nice feature of this sports watch is that you can personalize it perfectly. Via the "Garmin faces" app you can upload your own image as a background on your sports watch. There is nothing more motivating during exercise than seeing the image of your loved one(s) appear on your sports watch every now and then. The strap of the sports watch would also be replaceable. I'm going to stick with the black strap, but that is of course a matter of personal taste.

If I have to list one downside, it is the accuracy of the sports watch. We all know that a heart rate measurement via the wrist is often less accurate than via a heart rate belt. I have already noticed that the heart rate function of this sports watch is not always accurate. For a professional athlete, this might pose a problem. For the more recreational athlete like myself, the data is still sufficiently accurate. Plus, I'm not a fan of those often "annoying" heart rate straps around the body.

What I also regret is that you cannot consult the GPS on the sports watch itself. Nevertheless, the GPS is extremely accurate and detailed available in the app on your smartphone.

Before my purchase I spent hours on the internet reading reviews, making comparisons with other sports watches,... The Garmin Forerunner 235 costs quite a bit of money, but you get quite a lot in return. This sports watch is the absolute number 1 in its category! I have not regretted my purchase for a second.

excellent device

  • beautiful and easy to read screen
  • pleasant to wear
  • good heart rate measurement
  • no virtual partner

A "second chance" from Coolblue convinced me to buy this device.
I haven't regretted it for a minute. I think the strong point is the beautiful and easy-to-read screen that you can set yourself.
This is also a blessing for those who see less well.
The heart rate monitor also works great.
The speed measurement regularly loses north after a sharp bend, but that recovers quickly.
Garmin's site is also positive, with a lot of options.
In addition, there is also an app for Windows Phone, but for version 10. This is not available from other brands as far as I know.
The timepiece is also so light that you can easily use it permanently. Moreover, it is also quite beautiful.
Just a pity that the virtual partner is not provided.
Maybe this will be added with some update.
In any case, highly recommended!
