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 :)

Fantastic watch and case is heavy duty and the dial is gorgeous . The movement never requires battery so that’s a plus . The illumination works perfectly fine and the watch is a great fit . The strap is soft and easily adjusted and lastly the specs are awesome . Material of the watch is great.

Ok.... this is a very good watch...It keeps very good time, assuming you wear it for at least 8 hours a day. I also give it a good 30 second "shake" before bed.... I find it comfortable to wear and not very heavy (on line it says it weighs a pound... I weighed it and find it closer to a little over a half pound) I had a Seiko dive watch when I was 21 and SCUBA diving.. This watch comes close to that performance level. It keeps good time, is comfortable and seem to be well built... The reason I gave it 4 (4.5) stars is the setup of date, time, etc... is that the stem is a little "sensative" or tricky to set... Once set, it works... I just found it a tricky to setup. I included a picture of me wearing the watch... I am 70 years old, 6 foot and about 215 pounds. I wear the watch on the inside of my wrist based on how I was taught to wear a watch when I was diving. The band seems to be wide enough to accommodate a bigger wrist than mine.

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

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.

I wanted an automatic as I know we are headed towards hard times, battery dependent is NOT what I want so far the watch is nice in terms of quality , even the band is comfortable. BUT , this thing is really small compared to every dive watch Ive worn since 1991 ... it's a lil mini .....I guess Ill have to get used to the small housing and package.... Compared it to my G shock.....it's NOT what many would be used to ....everything is shrinking today, must be the economy .lol ! It's a Beta Male watch UPDATED ! The watch loses 10 minutes every month .. I have to reset the time every month to keep it accurate as it's always behind and not accurate. UPDATE !!! A year later it last nite QUIT completely ...I cannot make it function So after a year of NOT keeping time it is a paper weight ! JUNK !!!!

masterfuly constructed ,, wears well,,, classic design,, at a fair classic price,,, a watch wearer's must get

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.

I have received the product and it is really amazing but I ordered for Ice Blue color but received mint color.

fantastic piece but big & heavy

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
