Yes it can, it is waterproof up to 50m, but only for swimming, not for diving. However, there are also much cheaper fitness trackers that are also waterproof, e.g. from Amazfit.

The back of the housing is made of plastic. Since you are allergic, you should make sure that you do not have a reaction to plastic. If you are concerned, it may be helpful to consult a doctor or dermatologist to make sure you are not allergic to the material.

Yes, heart rate measurement on the wrist can be deactivated. - Press and hold the UP button or the menu symbol on the display. - Select "Fitness" > "Wrist heart rate" > "Status" > "Off". Please note that deactivating the heart rate measurement also deactivates the sensor for measuring the pulse oximeter on the wrist.

Yes, the Garmin Forerunner 55 has a sleep recording and analysis function. The watch can track and analyse the duration and phases of sleep, including light, deep and REM sleep. This data is then displayed in the Garmin Connect app and can be further analysed there.

Hello yes, mine offers Turkish in the menu on the watch. MfG

The activities can be tracked with the Garmin app and then connected to Adidas and transferred directly.

Hello, 1) yes and 2) yes too 😃

No, the watch itself does not have internet and therefore has no access to Spotify. The watch is also only a "slave" and not a "master", i.e. it can only be connected to the phone but no other devices can be connected to the watch.

Yes, an alarm clock function is available.

I have the Forerunner in black and have no problem pairing it with my iPhone.

This has to be a mistake, I have the black one and it is compatible with iOS

Not as far as I know. It only functions as a remote control for the player on the smartphone.

Hello Paula, I was Polar user form many years, but when I needed more accurate and faster GPS I switched to Garmin. A have two models Fenix 5 and Forerunner 55. The newer Forerunner have little bit more accurate GPS and built in hearth beat sensor. Sensors for bike are better from Polar not because of accuracy but the way how you can fix them. So for walking I would sill recommend Garmin. Even the not so expensive one. I would suggest also to try how they fit on your wrist as they have different sizes. You can use also the Forerunner 55 as I have. The only problem I have with this model is that the battery in mine doesn't last long and sometimes I deplete the battery completely, which leads to that I have to switch on the running program just to connect to GPS nad get correct time again.

Unfortunately, we do not offer a longer version for the model in question.
