    I am very pleased with my purchasing experience from Yamatonadesiko. The shipping was fast and was packaged very well. The watch is amazing. Very solid and built tough. What got me sold on the watch is the sapphire crystal. Very scratch resistant. I am very glad that Casio picked sapphire crystal as a new feature on the G-Shock. that is the main reason I bought the watch. I already have a few frogman, but I needed to get this one because of the sapphire crystal. Job well done Casio. The price is justified if you ask me. Customer satisfaction is priceless. Thank You Mr. Kazuki. I’m done jumping up and down with my new Frogman.

    Yamatonadesiko company wow. I found this site by accident & noticed they had great pricing on great watches. So I purchased 2 Master of G watches. 1 ) Frogman diver 2 ) the Mudmaster. both better than I expected. I was also amazed on how fast I received these watches. Purchased on Mar 9 & I was opening packages just a few days later.I Will also say it was free shipping. Customer service was 2nd to none with fast reply to my question’s Needless to say I will be shopping there soon looking for a my Seiko dress watch Can’t wait. & special thank’s to Kazuki…….

    I believe this one will survive a nuclear blast.
    First class packaging and shipping, you can’t go wrong with the Yamatonadesiko purchase experience.
