This watch is only sold in Japan, but I got one thanks to Ippo. I can verify that the SBXY087 does work in North America using the WWVB time signal! However, one thing to keep in mind is that this watch was intended for the Japanese domestic market only, and Japan does not observe daylight savings time, so anyone in North America or Europe who buys this watch will have to manually change the time zone twice a year. Other than that, it is a very nice low-maintenance watch. The sapphire crystal is so clear that I can barely see it, and the titanium case is very lightweight.
