I'm an international buyer. I wrote this review after I've worn it for more than one week. It's a nice watch, no need to adjust time, no need no change the battery. Only one thing: the digital screen isn't very clear to see sometimes. You need to adjust the watch to a right angle to see it clearly.
It took 3 days for my order from Rakuten to the shop, 1 day to pay, and 3 days from Japan to my hand. It's really fast for international shopping.
