    Thank you Yamatoadesiko for making my watch purchasing experience wonderful! It arrived much sooner than expected and the purchase process was easy. The Gulfmaster in Marine Blue is one of the best G-SHOCK watches in my collection. It’s the first of its kind with the Quad Sensor and it all works well! I plan on purchasing more watches from this vendor!,

    If you want a great experience purchasing a QUALITY watch from Japan, this is the site you want to use; make sure to work with Mr. Kazuki! I was referred to this site after watching G-Shock High Fashion because I wanted an authentic Japanese manufactured Casio G-Shock Master of G; JDM. This the site for that! Mr. Kazuki was more than helpful, and he went above and beyond the norm to help me. I research everything prior to purchasing, and Mr. Kazuki assisted me with this; we exchanged over 30 emails combined prior to me making the purchase. Mr. Kazuki is very honest: when I placed my order the site didn’t credit me the full 1000 JPY for a coupon code I used, but My Kazuki caught the glitch and credited my credit card; I didn’t even realize there was a mistake. The watch shipped from Japan on Feb 28th 2018, and I received the watch in California on March 3rd 2018. I LOVE THIS WATCH, and I LOVE THE JAPANESE JDM quality. I own many watches, and I have owned many watches (Rolex, Omega, Breitling, Raymond Weil, Grand Seiko, Casio, and Techno-Marine), and this is one of my favorites of all times. This is just a super cool, fashionable, functional watch which is very applicable to people who love yachting! Please, enjoy!

    To buyers out there, YAMATO-NADEISKO is the right vendor to make your purchase.
    It took 2 days for them to reply your purchase & shipping took over 4 days including weekend to reach Singapore. Very fast shipping! Shall purchase again someday.. Thumbs Up!
