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

Pretty sturdy watch. Easy to use and practical.

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

Good watch .Been using it for a few days. Didn't see any problems. Shows time accurately. I also really liked the design. Tried the water test. No problems. Will update after using it for a few years.

Excellent watch

A work of art and quality Really happy with the feel

This watch exceeds expectations even as compared to a much more expensive brand. The look, comfort and functionality are excellent! This is my first purchase of this brand. I will certainly be buying more.

Durable

Bought it for the specs as a collector - saphire crystal 1000m helium safe nh35 movement Heavy watch but looks good! Kept good time keeping for past 3 days! Gave 4 stars as not aware of the life it will give me. So will update after 3 months

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 ,

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...

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 :)
