"Nokia Steel HR"Although it is an ordinary analog type wristwatch, it is a smart watch that measures heart rate, sleep rhythm, step count, etc. and records it in conjunction with the application.

◆ opening
It is a package of Nokia Steel HR. Two models of white and black are prepared for each model, but this time I could borrow 40 mm model black (left) and 36 mm model white (right).


Specifications such as 5 ATM water resistant, battery performance, automatic synchronization by Bluetooth Low Energy etc are written on the side of the package.


When opening the package Nokia Steel HR jumped into my eyes. At first glance it looks like an ordinary analog watch.


After taking out the inside box and flipping it over, the charging stand entered the bag and was stored.


Only Nokia Steel HR entered with a charging base, instructions, written guarantee, very simple.


I looked at the 36 mm model (left) and the 40 mm model (right) side by side. The wristband is available for 36 mm model up to 200 mm around the wrist and 40 mm model for up to 230 mm around the wrist.


Although the contents and functions are exactly the same in the 36 mm model and the 40 mm model, there are bezels with minutes carved around the surface of the 40 mm model board.


The weight of the 36 mm model is 39 g, whereas the weight of 40 mm is 49 g.


Nokia Steel HR's dial is a simple design with only two needles, a short hand and a long hand representing time. There is an LCD screen on the upper central part of the board surface and an activity dial showing the degree of progress of the target step count at the center lower part. The glass is made of mineral glass.


There was a button on the side of 3 o'clock on the board, at the position where the crown is attached if it is a general analog clock.


When turning over, the heart rate sensor was built in the center. When the button on the side of the main body is pushed, the internal LED glows green and senses the change in the blood concentration of the wrist and measures the heart beat.


There was a terminal for charging under the heart rate sensor.


The thickness of the main body is 13 mm. When viewed from the side, the back side is rounded like a dome. The following image shows a 40 mm model of Nokia Steel HR superimposed on a 7.0 mm thick iPhone X.


It is like this when a man editing member puts a 40 mm model in his arm. I was worried about whether the back side containing the sensor was swollen because it was swollen, but it does not matter at all if I actually wear it. It looks like an ordinary wristwatch, it is a simple design that seems to be able to wear regardless of age and young man. Also, pressing the button on the side displays the digital display and heart rate on the liquid crystal panel on the board surface.


Both models included the wristband was a black silicon type. Spring bar type wristbands are interchangeable, spring-type wristbands with a width of 18 mm for a 36 mm model and 20 mm for a 40 mm model can be used, so it is ant to replace according to preference.


The charging base is a USB connection, but the USB adapter was not included. It must be connected to PC or prepared separately.


By checking the position of the terminals and buttons, the watch fits the charging base with pulling by magnetic force. Because the magnetic force of the charging base is a little weak, there are parts to be fixed slightly.


◆ Set up cooperation with smartphone application
In order to measure heart rate and measure sleep rhythm with Nokia Steel HR, it is necessary to cooperate with application of smartphone. The application to be linked is "Nokia Health Mate" released by Nokia for free, and iOS version and Android version are available.

This time iOS version is used. Tap "Get" to install "Nokia Health Mate".


When you start Nokia Health Mate, first tap "Create account only" in order to create an account.


I will move on to the account creation screen. Enter your e-mail address and password, check the agreement to terms of use and personal information protection policy, tap "Create" in the lower right.


Since it changes to the profile input field, enter name, surname, gender, date of birth, and tap "Next" in the lower right.

Then tap "Steel HR".

Updated Nokia Steel HR ......


Calculate minute hand, hour hand and activity dial when done. While looking at the face of the watch, swipe the dial displayed on the screen and tap "Next" when it matches the position indicated.


This concludes the collaboration between smartphone and Nokia Steel HR.


◆ I actually tried using it
Since it means that it can be used for up to 25 days with a single charge, I charged it to 100% after opening it and continued to use it with the notification option enabled without any charge as it was. Then, the remaining amount of the battery was 84% ​​in 1 week use. Certainly, charging will be sufficient calculation even once a month. A perfect digital smart watch such as Apple Watch almost always needs to be charged every day, so if you do not worry about the battery and keep using it for a week all at once it does not worry about running out of the battery, it's pretty big It is merit.


When you press and hold the button for a long time, it switches to continuous heart rate mode, measurement will be done every second. Switching to continuous heart rate mode will allow you to monitor fine heart rate changes during training.


Because the silicon type gets caught on the wrist carefully, it can measure the heart rate and the number of steps accurately, and as compatibility as a wrist watch with activity meter is good, compatibility is worried that it will be steamed a little if it keeps on all the time Place However, there was hardly anything that actually wears, and I was concerned about weight and thickness.


Under the activity dial, "5 ATM" and 5 ATM waterproof function were shown. It is a waterproof gradeIPXThen it is unknown what kind of hit it is, but when the shower was bathed with the editorial staff inadvertently attached, there was no such thing as troublesome operation or trouble occurred.


As long as you are sleeping, you will measure the sleep time, sleeping heart rate, and depth of sleep and record it. The result can be confirmed by the application. Accuracy is higher than I expected and it is well recorded in the application, so I can grasp my sleep quality.


Also, if you set an alarm, Nokia Steel HR will vibrate and wake up. Vibration is strong enough to surely care if wrapped around the arm. However, because there is only one alarm that can be reserved, it was regrettable that even if you wanted to set multiple alarms, you can not do it.


If you register friends and family using Nokia Health Mate, you can compete for the number of steps. Two editorial staff wearing 36mm model and 40mm model this time, I competed for one week with each other, the difference of overwhelming momentum became clear. This function is pretty ant, as the consciousness that someone is watching, being trained by someone is strengthened and motivation continues.


If you wear Nokia Steel HR and train, you will be unlocked with the application. For example, the following results are "from the left" walked 4000 steps a day "," walked 6000 steps a day "," walked 8000 steps a day ".


◆ Summary
Actually using it, it was design and battery holding that was attractive anyhow. A simple design based on an analog watch makes it easy to fit various clothes as well as to understand time at a glance without any operation, and can be used well either in work or private. Also, since charging can be done only once a month, I felt that it is not necessary to worry about the battery level at all. It is easy to cooperate with the application, because it automatically discriminates actions such as walking and sleeping and records it, I felt little trouble. Recommended for those who want to manage their own life rhythms and training with smart watches.
