Customer Feedback

  • Perfect service. The watch was in perfect new condition as advertised. The watch was shipped and arrived from Japan to my location in New York within a matter of days. The watch was safely and smartly packaged. There was a lovely note from the seller as well as a small gift of thanks included with the watch and case. It's those kinds of details of professionalism that make you feel extra happy about your purchase and confident about the quality of the seller, The watch itself is even better than advertised by the brand in terms of precision and accuracy. I highly recommend and trust this seller.

  • This is my second purchase of a watch from Time-Japan—both Omega Constellations.

    Everything was absolutely perfect—great product and price, cordial and professional service, fast delivery, trust in the transaction. This firm is high on my list of go-to firms for watches and gifts.

  • Das war meine erste Bestellung einer Uhr in Japan. Ich bin rundum zufrieden! Der Zustand der Uhr ist tadellos, besser als es die Beschreibung vermuten ließ.In einer knappen Woche war das Paket bei mir. Abwicklung mit DHL Express völlig problemlos, kann diesen Händler empfehlen.Bestellung aus Deutschland, EU.

  • The Time Japan team is truly first-class.  The Speedmaster Professional I purchased is beautiful.  After placing my order, the timepiece was promptly shipped.  From start to finish the customer service was exceptional.  If you are looking for a luxury watch at a great price, with a knowledgeable and trustworthy staff, I highly recommend Time Japan.

  • Time Japan had the model that is impossible to find anywhere else in the world. I never felt that they were merely a merchant selling watches, but someone who really cared about the customer and gave them a service that rivals one you get in an Omega store in Switzerland.. I would never hesitate to order my next dream watch from them again. Great prices too. Thank you Time Japan, ARIGATO! ♥️

  • Everything with this watch purchase was PERFECT! The Japanese firm quickly responded to my questions. They were very nice and helpful people. I received a note stating that the watch may take up to 2 weeks. It arrived in about one week. Also, great price--better than a 45% discount over the price at a jewelry store, so I saved about $3,500. All packaging and warranty cards were included for the Omega Constellation watch. This was a college graduation gift for our son. He is beyond happy. He took the watch to an Omega store to get it fitted. They did this for no charge and told him, "Welcome to the family!" I will definitely buy other things through this company.

  • The dealer was very professional and promptly responded to all my questions. They put in the extra care when it came to packaging the Watch and its contents. The Watch was new, unworn and absolutely beautiful as described and there was a nice note from the dealer accompanying the package. The shipping to Texas was fast and there no customs either as the dealer assured. Will definitely look to buy my next timepiece from them. Highly recommend them. 👍
