The old series name "CITIZEN Eco-Drive Bluetooth" (BZ1034-52E), which was released in March 2017, will be upgraded to support Riiiver by upgrading the application.

There are various types and classifications of so-called "smart watches", but in terms of charging management, the old "Eco-Drive Bluetooth" (currently CITIZEN CONNECTED Eco-), which can be charged with indoor light, is a Citizen watch. The Drive W770) series is unique. It is based on analog watches and has the minimum smartphone linkage functions such as notification linkage and alarms, so it is an attractive one for those who are purely "watch lovers". It can be said that it is a platform. Some readers may already be using the aircraft for the reasons just mentioned.

The old "CITIZEN Eco-Drive Bluetooth" was released in March 2017, but on June 15, 2021, a firmware update made it compatible with the new IoT platform "Riiiver", and the series name. Has been announced to change to "CITIZEN CONNECTED Eco-Drive W770". From August 17th, a notification prompting for a firmware update has also been delivered.

Therefore, in this article, we will introduce the change procedure for "Riiivering W770" for users of the old "CITIZEN Eco-Drive Bluetooth" (hereinafter, W770).

What is "CITIZEN CONNECTED Eco-Drive W770" in the first place?

If you look at the official website of "CITIZEN CONNECTED Eco-Drive W770" (hereinafter referred to as "W770"), you will first see the catch phrase "Connecting, authentic analog clock." As the word says, the aircraft is an analog wristwatch, but it is a product of the genre commonly called "connected watch" that can be connected to a smartphone to use notifications.

There are nine variations of cases, bands, colors, etc., including new models and models that continue to be sold, and the model names are divided by notation such as model number. This time, I used "BZ1034-52E" from them.

BZ1034-52E uses super titanium for the case and band, which is more than 5 times harder than stainless steel by applying surface hardening technology Duratect to titanium.It is a long-selling model with a reputation for being comfortable to wear with its lightweight and sharp design.

In the case of the same model, the case and band are made of titanium-based surface-hardened material, and the color is silver. The accent color is the tachymeter in blue letters on the bezel and the orange on the crown and second hand. The bar index and pencil needles are used to create a classic Citizen-like design.

By the way, in order to pair the W770 with a smartphone, the "CITIZEN Bluetooth Watch" app was used at the beginning of the release.

The image is the "CITIZEN Eco-Drive Bluetooth W770" app on the App Store.

By the way, even within the scope of my understanding, the name of this app seems to have changed several times, such as "CITIZEN Bluetooth Watch"-> "Eco-Drive Bluetooth"-> "CITIZEN Eco-Drive Bluetooth W770".

For example, in the information on Citizen's official help page, which is a hit on the net, the notation "CITIZEN Bluetooth Watch" was still used. When searching for how-to information and help pages on the Internet, I think that you can prevent confusion if you understand in advance that multiple application names are mixed.

Specifically, you can check the intensity of the light that the watch is shining on, and set alarms and notifications. Although it is used less frequently in Korona-ka, it also has a function to correct it to the local time overseas.

For example, since the intensity of exposure to light can be confirmed for each time, it is easy to understand that the difference in intensity such as the timing when the clock was placed on the window side and the timing when it was hit by the interior light could be visually recognized on the graph. Felt. In addition, since notification settings can be set for each app, we were able to meet needs such as "I don't want to link Twitter notifications, but I want to check LINE on my watch."

In the "CITIZEN Eco-Drive Bluetooth W770" app, a screen that shows the intensity of the light that the watch is bathing in. It changes in the order of (weak) blue → yellow → red (strong) depending on the intensity.As shown in the image (right), you can also check the graph display by time.

In addition, as an operation on the watch side, for example, by pressing two buttons (2 o'clock position and 4 o'clock position) at the same time, the sound of the smartphone being paired is played and the function to reversely detect and search for the misplaced smartphone etc. Was convenient.
