    Watch Purchased:
    I ordered a Casio watch GWG1000-1AJ. The watch is authentic, & it was shipped in a well made containment that prevented damage. The salesman, Mr. Lazuli was very helpful keeping in touch and answering any questions I may have. Anyone buying from this business, is in good hands!…you can trust them👍‼

    Excellent watch and excellent prompt customer service. Although some of the grammar is lost in translation, I speak little to no Japanese so I cannot fault them for that. They had the best price I could find for this watch and they delivered it quickly and with tracking.

    The watch itself is a stunner, if you are on the fence and have a medium to large wrist this is the most fun G Shock of them all. I have a rangeman and it is certainly more useful and easier to navigate, but it does not compare on the looks side. Be aware all adjustments are made with the smart crown that you almost always have to take the watch off to use.

    Enjoy it in good health!

    The GWG-100-1AJF was my first purchase from Kazuki, so I wasn’t really sure what to expect. Couldn’t have asked for a better experience. Best price on the web plus prompt and courteous notifications via email. About 1 week from the time I placed my order until it arrived at my door in the United States. Was able to track the shipment and it arrived well packaged and with all receipts and warranty information enclosed. Buy from Yamatonadesiko with confidence.

    As far as the watch itself goes – wow! This is a big, substantial piece. Very high quality construction. This thing looks like it could survive a fall out of an airplane. Instantly my favorite among all my other Casio G-Shock models. Waited a long time to buy this particular model but I’m glad I finally did. If you’re on the fence about whether to get one of these just do it. Good looks, tough as nails, and tons of functionality. Fantastic watch!
