FreeDiver Helium-Safe Dive Watch Sapphire Crystal Automatic Diver Watch 1000M Water Resistant Diving Watch for Men

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 Amazon. 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 :)

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.

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.

The watch seems to be very well made with some quality features I look for like the sapphire crystal,great luminescense, great water resistance, auto winding and a Sekio movement that has a great track record for working very well. I love the style and it is pretty comfortable too. The only negative, which doesn't bother me much, is that it runs a little fast. But it's less than a minute per day and if it bothered me I'd have it adjusted to slow it down a tiny bit. It's my favorite watch out of the three autowinding diving watches I have due to its style and water resistance. I think it was well worth the money I paid for it.

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!

Great looking watch and it will be a keeper. However, watch failed 14 days after I had it on/off my wrist. Very disappointed that only work for 14 days and it stop ticking. Try manual winding and continues shaking and it still no movement. Dead watch. Will not buy again.

Very good looking, keeps excellent time. Seems to be very good quality very happy.

First off let me start out by saying this is a beautiful watch! I have a lot of different watches & have had many others over the years & i know a quality watch when i see one. Time will tell how well this watch keeps time but this watch checks every other box pretty much that i look for in a quality well built watch. The packaging presentation was also pretty nice. I do not dive at all so i will never come close to pushing the watches limits. I do spend a good amount of time in & around water though so it nice knowing this watch exceeds any situation i will ever be in. The watch has a good amount of weight to it. The second hand rolls it does not tick which you would normally only see in watches much more expensive. This watch seems like a good value for the price. Again it is absolutely gorgeous. Pictures do not do it justice.

bell'orologio da immersione di fattura robusta. Il movimento è preciso.

What a bargain ! great looking dive watch with helium valve . I use it in a medical hyperbaric chamber so haven't got it wet yet, but it keeps great time and is not to heavy. It appears to be well made and has a solid feel to it which I like. The luminosity is great and its easy to ready at night especially if its been in a bright place during the day. It claims to be 1000m waterproof I cant comment on that but I would be comfortable and will be recreational and tech diving with it ,

Just got my Free Diver Ratio 1000 m Helium Safe Automatic, the screw down crown is amazing and for a minute I was wondering how to get the watch initiated. Its a safe guard system and once released you can adjust the date day and time and hacking helps catch the seconds. Today the 18th Sept '25 my Ratio 'PI' watch arrived from amazon aand it is the first day of time keeping with it, so let's see how the watch movement delivers . The lumen is the best among all my watches, almost blue fluorescence and the dial is rather more Saffron in color and a beautiful Sunburst dial. Ratio does not have a service centre but it should be able to be serviced by local professional watch keepers! Will update this review after a good use of the watch

Nice white dial, decent weight, no issues so far,decent price, especially for the specs you get, very happy.

Excelente reloj, tamaño, peso, correa, mecanismo, colores, funcionalidad, estética muy muy bien, superó mis expectativas...si duda es de colección...y recomendable...
