Review: Good looking watch - I liked the look of this watch as soon as I saw it, I was afraid the face would be too small but it’s perfect. This is now one of my favorites and would wear it everyday if I didn’t work in a factory environment. Watch seems very rugged and the band is comfortable. Pretty sure I won’t be testing the 1000m water depth but have always liked the look of Divers watches. Hopefully it turns out to be a good purchase and it holds up for years. I also bought a watch winder since I won’t be wearing it daily. Very classy looking watch and has a Seiko movement and never needs batteries!
Review: Remarkable watch - I found it impossible to not fall in love with this watch. This watch delivers beauty, functionality, precision, robustness and lumes galore. Granted, I could have waited months or years to leave a proper review, but given that the watch may not even be available years from now, I can only update this review at a later date if something changes. This watch either gains 0 seconds, or 0.5 seconds in the few days I have worn it constantly, including showers, dish-washing, sleeping, but alas, not diving yet. The precision blows my mind. I do have a 20 years old Eco-drive that basically keeps atomic time (no radio) and to get this kind of precision on an automatic is either luck or the stuff of legends. As others have stated before me, this watch is a tank. It even looks like a melted tank. Everything is so precise and gorgeous, including the bezel action. Simply delicious sound as you rotate it and it comes to a fully centered state. The lume, as imaged, I took from inside a closed closet and adjusted the camera to image as close to what my eye sees. The lume lasts through the whole night, all the way to the morning hours and is easily readable even then. I don't do anything special to charge it. The image was taken after 5 seconds exposing to direct sunlight, but even in office light, and then going to bed, it just shines, almost like it is an LED. Simply remarkable. There is no question that the watch can easily be upgraded to be even more gorgeous but clearly that would increase the cost without increasing functionality, and this watch is incredibly functional. Now, the silicon straps that it came it, I replaced with the nylon straps, but those too are far too short. If you have large wrists, like I do, I barely get to the very first hole without cutting the blood circulation and that is annoying and has nothing to do with the watch itself. It is also nearly impossible to get XL canvas or nylon straps (non Nato) from desertcart. Many brands say they have XL versions, but no option to select during ordering. So I wonder if this watch could survive for however long on the surface of Venus, with surface atmospheric pressure of about 92 bars and 600 degree Fahrenheit temps. Both the melting point of sapphire and steel are much higher, so who knows :)

### ⭐⭐⭐⭐⭐ Seriously impressed
*by R***Y on April 8, 2026*

I only leave two types of reviews. Usually the reviews are if products or support so bad I want to give people a heads up. Or in this case I am blown away by the product or services. This watch is phenomenal. I bought it as a work watch (I usually wear G-Shocks to work). I wanted something that looked a little classier and didn't want to subject my "nicer" watches to the beating that my work can do to a watch. I am blown away by this watch. I cannot find a single flaw. It's literally perfect. I can't comprehend how they can offer a watch like this that has such a nice finish, the Seiko movement and a mineral crystal. Crazy this watch has any bad reviews. I assume people just dont know watches that well. People complained about lum. The lum isnt mind blowing, but it is on par with my SKX's and Ecodrives. I get people having timekeeping issues, that would be frustrating. But this has a Seiko NH36 movement that can be easily adjusted to correct that, there are vids on YT showing how to do it. I love this watch, value per dollar is nuts. I will be buying more Ratio watches, hopefully before people start recognizing the brand and price goes up. Hope this helps
