      Blazing fast delivery, great customer support and amazing watch

      Posted by Phaisal Guladee on 19th Jun 2021

      First time purchasing with this site. The customer service is really nice, and the shipping was blazing fast. The watch was packaged nicely and there were a few goodies in the box. Will definitely buy again. The watch itself is just stunning! Nothing much to say just get it and experience it yourself. Highly recommend. Those from Thailand beware, the import tax and import VAT could take your watch up from the base price by 10-15%.

      SBBN031

      Posted by Vlatko on 19th Feb 2021

      The SBBN031 is a great watch with a great movement and a very good bracelet. I love the brushed finish on the watch. It wears smaller than you would think for its size a perfect fit. Shopping in Japan and Mina were a pleasure to deal with. Mina answered all my question promptly and the watch shipped fast and was delivered in a few days to the US. Highly recommend place to buy from.

      Wonderful watch and Effortless Purchase

      Posted by Neeraj on 9th Feb 2021

      Shopping on the site was smooth. Prices were reasonable and the service was good and prompt. -SBBN031- It runs on the 7C46 movement built exclusively for this range. A reliable movement that has never failed since it's inception in 1970's. The finishing of the watch and bracelet is immaculate. The bezel and crown work better than can be imagined. Looks big, however,the weight is well balanced. It wears well and is very comfortable on the wrist.

      Buy with confidence

      Posted by J London on 5th Jun 2019

      The Seiko SBBN031 is an excellent watch and there’s countless reviews online that attest to this. I want to emphasise here that you can trust SIJ and buy with confidence. Shipping to U.K. took around 2 weeks and I had to pay an import tax of around 20% that was expected. I recommend and will be using SIJ again. Thank you.

      Posted by Richard London on 9th Nov 2017

      I found the service to be excellent. shipping to the U.K. took about a week. Sara always emailed me and kept me up to date. With the tracking number she gave I could see my watch's delivery status all the time as it arrived in the U.K. and cleared customs. Great packaging and I am so happy with the watch. I will buy from Shopping In Japan again. Thank you Sara
