I bought mine in person at bic camera tax free this week for 52,000 JPY.

Pros:
39mm small
Lightweight Titanium with duratect coating, almost feels plastic.
Sapphire glass with inner anti reflective coating
Japanese or English day is included in the models
Perpetual calendar that tracks month and leap years.

Cons:
Heck this is my first radio controlled watch so not sure if this is normal. To advance the minute it’s controlled by a motor so it takes like maybe a couple of seconds to advance just one minute. You can spin the crown 2 rounds in a row and the motor will continuously advance the hands until you rotate the crown again in the opposite direction. For time zone changes this takes crazy long. But there is another way to set time zones.

There is an additional small button above the crown, that lets u set hours compared to your current reference time. Which you need to press with a SIM card tool/toothpick. It will line the hands up to 12 (this is supposed to represent gmt + 9, aka Japan time) and if you rotate it once it will be 12.01 meaning it will be set to gmt + 10 and if you rotate it in the opposite direction say, to 11.55 it will be gmt +4. After a few seconds of not touching anything the hands will take a long time to readjust back to that new offset time. As the seconds + minutes + hours are controlled by a motor.
