Pros and cons

According to our smartwatch expert
  • Thanks to the ECG heart rate monitor and the blood pressure monitor, you get accurate insight into your health via the Samsung Health Monitor app.
  • You can easily navigate through your apps and messages with the rotating bezel around the screen.
  • With the built-in microphone, you can use the personal assistant Bixby and answer messages via voice control.
  • To make a blood pressure measurement with the watch, you must first calibrate the watch with a separate blood pressure monitor.
  • The Samsung Health Monitor app is only compatible with smartphones with Android 7.0 or higher and not with iOS smartphones yet.

Description

With the Samsung Galaxy Watch3 Black 45mm, you're constantly aware of the most important information. You'll receive all your calendar or weather notifications on your wrist. You can also easily answer incoming calls from your wrist. Thanks to the ECG heart rate monitor and the blood pressure monitor, you also get accurate insight into your health. You can easily view and analyze your health data in the Samsung Health Monitor app. The watch is smaller, thinner, and lighter than its predecessor and has an adjustable leather strap. This gives your watch a stylish and timeless appearance. The Watch3 has different sport profiles, so you can also use it in the gym. Make sure to change the strap of your Galaxy Watch3, because leather isn't suitable for workouts or swimming.

Note: an adapter isn't included. Do you want to charge the watch from a socket? Use the adapter of your phone charger or order a separate adapter.

This watch is recommended for a wrist circumference of 17 to 19 centimeters.

The smartwatch of the moment!

  • Nice design, strap, luxurious look
  • Nice turning ring invites to play with
  • The strap is, as to be expected from leather, a bit tight/irritating in the beginning. This needs to be 'worn in', give it 2 weeks!

The smartwatch of the moment!

  • Nice design, strap, luxurious look
  • Nice turning ring invites to play with
  • Clear display, even in the sun
  • The strap is, as to be expected from leather, a bit tight/irritating in the beginning. This needs to be 'worn in', give it 2 weeks!

Very nice machine that does what it's supposed to do. Love the notifications and the nice round screen. Better than my Apple Watch 4 and 5 in my experience!

A very nice and modern smartwatch for both normal use and sports. Has almost all modern possibilities of this moment. Highly recommended so far! I chose the silver one because scratches are less noticeable there than with the black version.
