I bought this watch in December for a Christmas company party that I needed to dress up for. I likes the style of the watch so I bought it not expecting much. I always wore a samasung watch before hand. Now I never take this watch off, I work with the watch on (I'm blue collar and my gear always take a beating) somehow the more scratches it gets it just looks better over time. I did have to make a slight adjustment to the time tracking on it, it was running about ten seconds fast (the only complaint i have about the watch), but with some time tracking apps I've gotten it to the exact second for every day going on 3 weeks now. The watch is very comfortable to wear all day after the proper adjustments. At first I had trouble with it, but I was trying to figure out the band sizing to my personal liking. For the price of this watch i have no complaints whatsoever ever. The automatic movement of the watch is nice never having to worry about batteries or charging a watch, or winding it everyday (but you can still wind the watch if you wanted. And I'd recommend it right out of the box before wearing to get a good "charge" out of the watch before setting it) the dual language English and Spanish date indicators had me confused at first but after actually reading the instructions I figured out the proper way of setting the watch to only English (for a few minutes at night it will be in Spanish as it's switching over the day) the glow on the hands and hour markers are very bright and easy to read in low light settings aswell as it is an easy watch to read all together. I love how the watch does so little but so much at the same time. The water resistance hasn't be tested much by me, only while washing my hands, but if the crown is fully screwed in I have no worries about water damage. I would highly recommend this watch for anyone looking for a nice looking, and durable mechanical time piece for daily usage. Outstanding job Orient, you knocked it out or the park with this watch! PS- when storing the watch overnight, keep the crown stright up in the air, this is the best resting position for the internals as well as where Orient keeps the balance of the watch to keep proper time while being stores. ... show more

Full disclosure before writing - even though I consider myself a budding watch enthusiast, I don't have a watch collection or any other dive watches to compare this one to. In fact, this was the very first watch that I decided to purchase after doing my own research. And so I will mostly be talking about how the watch is like on its own merits instead of comparing it to other watches simply because I don't have much other watches to compare it to. A little context, I own/have owned: 1) A cheap Casio quartz watch that I used during high school (I am an undergraduate student right now); 2) An Apple Watch; 3) A Longines automatic dress watch that was gifted to me from my relatives. I knew I wanted to get a dive watch because I consider it a really versatile design, and I don't mean versatility in the spirit of the Apple Watch, which I would be comfortable wearing in both casual and formalwear, but at the end of the day is a downsized phone on your wrist. Why wear an Apple Watch when you can wear a classy watch? This Orient Kamasu dive watch exceeded my best expectations and I'm really satisfied with my purchase, and I encourage anyone else out there who needs a dive watch or just wants a non-expensive watch that really delivers value to consider buying an Orient Kamasu. I think the value you get from this watch is amazing. First off, it looks fantastic, both up-close and from a distance. I think that's mostly emblematic of all dive watches, though. If superficial looks was my only concern, then I would've just gotten an Invicta. I know it's a hideous thought for many, but Invictas do look (big emphasis on "look") fantastic for a cheap price. However, I really like how well it is performing so far. I estimate that in a 24 hour period, my watch gained about 2 seconds, which is well within what I hope for with an automatic watch, and is notably better than my Longines watch. I am not an expert on the different automatic/mechanical movements of the world, but I did notice that the automatic movements for Orient watches are produced in-house. I've always thought it was kind of weird that a lot of high-end Swiss watches all use the same ETA movement, so I appreciate that Orient is not outsourcing their movement technology to another company. Nothing against the ETA movement, of course - it is a fantastic technology. There are other characteristics that I like as well, such as how it glows quite well in the dark (though occasionally, it "glows" in the daylight and that makes the watch dial look a bit weird with all the "teeth" appearing yellow instead of white), how it uses a synthetic sapphire for the crystal (a step up from cheaper Orient dive watches using mineral), and how there's a nice, functional day/date complication. But what really drives home the deal for me is how I'm able to get all of this for a really affordable price. Performance and feature-wise, this Orient Kamasu punches far beyond what its price point would suggest. I believe that with both Orient and Seiko (both are part of the same parent company but are functionally independent), you really get excellent value for your money. As an undergraduate student, I do not think it's a prudent financial choice to spend my money on luxury Swiss watches, though I hope to start a respectable watch collection in the future. I think this Orient Kamasu is an excellent place to start, and I have no doubt I will be wearing it many years into the future. I cannot comment on the waterproofing aspect of the watch as I don't really swim nor dive and I do find the stainless steel bracelet a bit boring, but I don't have much to complain about it either. All in all, I would highly recommend buying this piece, especially if this is your first dive watch. ... show more

Pros: The red dial is super pretty, I don't see a lot of other watches with red dials. The lume is incredible, it stunned me the first time I saw it. The specs of the watch are great; 200M of water resistance and a sapphire crystal for this price is a great deal. The rotating bezel is really satisfying, it has a decent amount of resistance, but it's still easy to move. Cons: This is a small detail, but this watch is not built in Japan anymore. This Amazon listing still shows the "MOV'T JAPAN" text on the dial, which is inaccurate and misleading. I also found the clasp to be quite long, which makes it fit unevenly on the bottom of my wrist. I also wish the micro-adjustments on the clasp were quickly adjustable without tools, so it can be adjusted as my wrist swells during the day. The crystal is quite reflective too, but that's a characteristic of most sapphire crystals. Overall, I'm still very happy with this watch. I've wanted one of these for well over a year, and I'm really happy to finally get one. I can look past the flaws, since this watch is so great regardless, especially for the price. ... show more
