Amazing watch and fast delivery

My watch arrived in a timely manner, and well packaged. It was authentic, and it got through customs without any problems. I’d say it arrived about 5 days after I ordered it.

The watch itself is stunning. Great attention to detail went into producing it. The finish along with the gorgeous blue shimmer of the sapphire glass draws a lot of compliments.

If you’re looking to get this watch, I strongly recommend getting it from seiyajapan. I’m glad I went with him over Amazon or some other vendor

Great service

Great service from order to delivery. Very easy process for customs charges and fast delivery. Product excellent as expected. Won’t hesitate to use SeiyaJapan again.

Most Complete Elegance

Highly legible everyday business watch. Dial is a unique eggshell white with metallic undertones. Water resistance makes it versatile. The size took a minute to get used to, but now prefer it: you wear it, it doesn’t wear you. It has plenty of presence, but never gets in your way. Switched it to the brown leather strap to fit my style. Becoming a big fan of Seiya Japan.

Amazing watch!

Amazing watch and crazy fast shipping to the states!! Will order again for sure!!

Very cool watch, fantastic service!

Arrived in Canada in 4 days. Beautifully packaged. The watch is very cool, with a nice weight to it so you know it’s in your pocket. It really seems to be a premium quality tool watch. The seconds hand hits every marker. I appreciate that Seiya takes the professional step of setting the watch accurately before shipping, it’s fun to see it arrive on Tokyo time! Thanks Seiya, I can’t wait to purchase from you again soon!

An excellent unit of canonical Seiko diver

This is just what I hoped it'd be — a well-executed modern rendition of the Seiko 62MAS dive watch. It's nicely pleasing in person, with more visual interest than you can necessarily predict from photos. The dial, bezel, indices and hands all reflect light in a nice subtly active way.

Cool watch

Good craftsmanship, solid looks, good size for my wrist

Great First Impression

Shipping was fast and my item was in perfect condition. Purchased the combi V1 bracelet for my Gw5000u1jf and its a perfect fit. Thanks guys! Will definitely buy more in the future.

Great watch. Great service.

Couldn’t ask for a better watch or more prompt service. Thank you.

A fantastic bracelet for the G-Shock Square

This bracelet has really impressed me. It was easy to size, and it really adds a quality feel to my GW-5000. It’s very comfortable and balances out the watch nicely. I plan on adding more of these bracelets to my other G-shocks.

Seiya Grand Seiko purchase....again!

Returning customer. First class service, correspondence and buying experience. Mr Kobayashi is a gentleman and truly caring with each transaction. A pleasure to deal with.

I love my Seiko SVBR003 so much, I bought a second one from Seiya!

I think that says it all! The perfect every day watch.

Underappreciated gem

Top marks on delivery. I'd say the watch quality is astounding. Not something you see on newer models. The 6R15 is more constant performer than the 6R35. The dial is mesmerizingly black and the date wheel is blackened to match the dial (unlike the Shippo SARX059 i sold). This also doesn't have the annoyingly plasticky chapter ring. Simpler yet better. Signed crown is a cherry on top - yet having the 059 cupcake-crown would be even better. Great strap quality, unusual for Seiko. No Presage-text, which was the reason to get rid of the previous one! AR coating could use improvement to enhance the dial presence.

Also received this watch quickly and loving it :)

A fabulous tool watch and great service by Seiya Kobayashi. Loving the kanji option too.

Excellent Watch & Service!

Totally in love with this Seiko Presage SRRY028. The watch looks elegant and very high quality. The dial hits the light beautifully. Express shipping was excellent, I placed my order on a Monday and received it here in New York on Wednesday (two days earlier than est. delivery date). I hope to order more from Seiyajapan in the future. Definitely recommend.

Already a favorite!

I bought my first watch from Seiya almost 20 years ago and I have never been disappointed. He is the best in the business bar none! This new Alpinist far exceeded my expectations. Thank you Seiya San!

Excellent product and service!

The watch was excellent, but even better was the service I received. Seller was always quick to respond, the package was sent out quickly and well packaged, and even included a screwdriver to size the bracelet!

Beautiful watch as expected

Pictures give you an idea, but you still need to see these in person as you may hear.
Everything looks good and new. -3 seconds per day on wrist, +2 second lying flat.
The caseback sinks into my 7" wrist, so the 13.7 mm thickness isn't as bad as a slab sided case like Longines Ultra Chron diver or Tudor BB. Wears more like 12 mm thickness.
My package was held in customs until I submitted paperwork highlighting details and purchase receipt and it was over the Xmas/New years break. So bad timing combined with a random check. Got it safely in the end.

SEIKO Prospex Speedtimer Solar Chronograph SBDL085

Good service and fast shipping. I bought from this store for the first time, but I will definitely do it again in the future.
