(Continuation from yesterday)

Just because food costs are high, we discard people who have been indebted for many years as garbage. This is not for humanism but for IoT engineer.

So, this time - "I thought I'd try to replace battery by myself".

Even if I fail to replace the battery and destroy my watch, this is my "gratitude" for my watch that I have taken care of for a long time.

-----

I bought a battery (143 yen) at Amazon.com and attempted to change the battery by watching the video on YouTube.

I could not replace it as I expected.

I pulled the metal fitting almost, forcibly pull out the battery, and inserted a new battery.

-----

The two clocks are moving cheerfully now.

They can receive the radio waves everyday and adjust the correct time. the backlight also flashes properly, and the alarm sound is clear.

Both of them did considerably unreasonable in this battery exchange, so it may not do well,

In this way, the watch I have fixed by oneself is many times "cute" than a watch that I have not.
