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 :)
Review: Impressive quality at very fair price. - I’ve had and still have several dive watches over my 58 years on this planet. I still on rare occasion use two of them when suited in full scuba gear. I wasn’t expecting much for the under $200 paid. To my complete surprise this is a very impressive, well designed and constructed time piece. I’m a beefy 6’3” guy and the size is just right, time accuracy appears very accurate, the lumination is excellent, beautiful scratch resistant sapphire crystal, very stylish classic dive watch that’s built like a small armored tank for your wrist. I’m so impressed with the quality I’m thinking of ordering another color thanks to the price point.

### ⭐⭐⭐⭐ 4.5 Stars - Almost Perfect
*by B***E on April 18, 2024*

This is a beautiful, well-designed and well-built dive watch at a great price. I have only two complaints, the first of which is minor: (1) The bezel rotates too easily, so it gets knocked off its setting with an light bump. (2) The watch is advertised as having a 47mm case, which is the perfect size as far as I’m concerned, but this one is smaller than my other 47mm watches, for example the 47mm Invicta Grand Diver in the 2nd photo (blue-green dial). The Ratio FreeDiver is even smaller than my 45mm Aragon Divemaster TI (white dial). Perhaps the bezel doesn’t go all the way to the edge of the case, making it appear smaller. Whatever the reason, I took off a half-star for it. Overall, this is a handsome, accurate and reliable timepiece I would recommend to anyone. Just be aware it is not as large as you might think.
