Beyond Expectations October 2, 2018
Reviewer: Jeffrey Jacquart from Barrington, RI United States  
Visually the sumo is a serious statement on the wrist. The case work is really a step up from the skx line. The high polish and brushed surfaces are immaculate.

Now I don't know if it is just my watch but the 6r15 movement is running +1 seconds a day. That is rock solid the same every day and I have been wearing the watch daily for two weeks. I own a Sinn 556i with an Eta 2824 top grade movement that runs 5 seconds slow. The Sinn was twice the money.

The watch was delivered on time with absolutely no issues.

Thanks Long Island Watch.

Seiko Sumo SBDC031 August 15, 2018
Reviewer: Daniel De La Cruz from Fresno, CA United States  
I couldn’t be happier with my Seiko Sumo SBDC031! The quality & design of the case is absolutely stunning! The design & choice of hands on the dial are a grand slam! I’m one of the few that really like the font on the bezel. In my personal opinion the bezel goes perfectly with the design of the watch. Gotta love the signed crown! I also love that the Sumo has a 20mm lug size bracelet that tapers down. It’s just another attention to detail that makes the Sumo so special IMHO.So far it’s my favorite Seiko I own! Long Island watch made the purchase very enjoyable & the communication was top notch! Mark makes sure all his watches pass his Quality control & that’s why my sumo has perfect alignment with the bezel chaptering & markers. Because of my experience with Long Island Watch I have become a loyal customer! Highly recommend the Seiko Sumo!!

Seiko Sumo - ABDC031 July 3, 2017
Reviewer: Neil Ziesing from Montclair, NJ United States  
Although I already own several other Seiko dive watches, the Sumo was still at the top of my "must own" list.  As always, the watch arrived in record time and I was amazed at the fit and finish.  Thanks to Marc's Youtube video on the topic, bracelet adjustment was a breeze.  Now deciding between the Marine Master 300 and a Blumo.

Excellent watch and customer service. February 19, 2017
Reviewer: Michael Williams from PA  
Watch is as near  perfect aesthetically as I can imagine.   Indices, Check your ring, and basil ring all line up perfectly.    Date lines up in the window almost perfectly on all dates.     Indices appeared to be applied. Lume  is excellent and long-lasting.    I can go to bed at 10 PM, wake up at 5 PM when it is still dark and I can still tell the time.   I have now had to watch for a couple of weeks and the watch has settled into being 8 to 12 seconds  slow per 24 hours.    I might keep the watch for another few months and then contact the seller about possibly having a service done to speed the watch up a bit.    If a watch is going to be off, I would really rather it be fast but unfortunately, I have three Seikos  and they are all a bit slow.   Purchase was conducted over the phone with Long Island watch.    Over the phone service was fast and excellent.    No problems to report with service in any way.
