Insane value
Without a doubt, some of the best value you can get in a diver watch. I've had this watch for a little bit now, and for around $100 it punches far above its weight. Dependable movement, solid build quality, and great looking. The watch is stunning in person, photos don't do it justice - I got the mint green shade, and it's beautiful. Within my first day of wearing it, had a few comments from coworkers and clients. It's solid, easy to read, and the lume is quite bright. Size is great, and so far, seems very durable - has that solid quality feeling to it. I have at this point around 20 watches, some sub $30, some in the hundreds, so not the largest collection ever, but I have a range, and have to say this is one of the most impressive I've gotten in terms of what you're getting vs what you paid for it.

An awesome watch with all the bells and whistles at a great price!
The watch is so good I ended up buying a couple more. The 40mm case is a great fit for my 6.5 inch wrist and the mint green dial is so striking. The dial is also very simple and easy to read on top of being stylish. I have noticed that it can be a couple seconds ahead a day, but that is better than being a few seconds behind. Accuracy is decent for the movement it came with. The weight is nice, but I did end up replacing the metal band for a NATO strap. It's proven to be fairly durable after taking a few knocks and bumps at work or a swim in the pool. The lume on the watch is also great! The lume was very strong before I went to bed and was still glowing strong when I woke up in the middle of the night! The rotating bezel is also well aligned and is so satisfying.

Well priced for a well built watch
Exceptionally handsome watch, built well, screw-down crown, crisp bezel nice bracelet with easy release. Wears well not too heavy not too light, it's a medium size well suited for most wrists comfortable all day wrist hugger and so far rugged for most activities. The movement is a reliable brand and keeps time as well as more expensive automatics up to 40+ hrs. Initiation 30-35 hand wind. This is my third Ratio watch (I have one at 500m and another at 1000m both automatics) and I find that the build quality is very consistent and the watches are well priced for a whole lot of watch and competitive with others in their respective class.

Built like a tank looks like 1,000,000 dollars and super affordable!
This watch exceeded my expectations. It’s truly well made. The finish is equal or better of some of my more expensive watches in my collection at only a fraction of the price. The lume is nice and bright as good as my Seiko and Orient watches. The NH35 Seiko movement is a proven work horse. To top it off the watch has anti reflective sapphire glass crystal. The back has beautiful etched image of a diver. rated for 200 meters. A decent well made stainless steel bracelet with solid end links. The rotating bezel is solid and has a very satisfying mechanical click well crafted. I love there is no cyclops lens makes the watch face look clean and refined. The crown is screw down is hackable and easy to get an accurate time setting to the second. If I didn’t buy this and got it as a gift I would put the price around $400-500 as the quality and value is definitely there. The only thing I did not like and it’s a personal preference the bracelet is a bit too shiny the center links and clasp. I will be buying a few other colors.

Great watch cheap packaging
Great watch, it’s a great size if you have smaller wrists. Really good lume quality and easy to read hands. The sapphire crystal is great for durability and it’s a Seiko movement so I expect it last and be fairly accurate for the price. Only reason to drop a star was the packaging seemed incredibly cheap it was shipped in this plastic sheet material

Worth the money, good quality
Great watch. I bought 6 months ago and wear it 70% of the time. It just fits well and looks good. Very comfortable. I get comments on it and friends have seen it and bought their own. I rotate it with a garmin smart watch when i want vitals. I have many other decent watches and go for this one most of the time. I dont review a lot but this watch was worth it. No scratches on the sapphire crystal either which was a major selling point at this price.

Outstanding Value in a No-Nonsense Diver
The RATIO FreeDiver delivers fantastic specs at a refreshingly affordable price. With its sapphire crystal, 200m water resistance, and reliable Seiko NH36 automatic movement, this watch is built for real-world use—not just show. The brilliant blue dial and ceramic bezel give it a clean, modern look, while the strong C3 lume ensures visibility in low light. It wears comfortably and feels solid on the wrist, whether on the included bracelet or a NATO strap. If you’re after a rugged, stylish diver with legit credentials, the FreeDiver is a smart pick.

If you're on the fence, buy this watch.
I rarely write reviews, but feel compelled because this watch blew me away. Firstly, it's beautiful and can be dressed up or casual. The quality is so much more than I expected for the price (materials, movement, overall appearance). It keeps great time and it's my new favorite wear. Every time I see this watch pop up in my Amazon searches I want to buy it again! Feels great, looks great - solid product for the price.

Très satisfait de la mienne : je l'ai depuis 2 semaines et elle fonctionne parfaitement même après l'avoir échappée par terre à 2 reprises. Elle fonctionnait toujours sans l'avoir protée pendant 36 heures. C'est un très bon rapport qualité/prix.

I'm a sucker for Diver's watches, long time ago I was a SCUBA diver. I just love all the different colour combinations available now on these watches. This yellow face watch now completes (I hope) my selection of divers watches. I have Green, Red, Black, White and Blue faces with various gold/silver bracelet and case combinations. They are all pretty much the same but for the colour, most automatic a couple of Quartz. As I already said I don't dive any more but the rating on this watch at 200M should make it suitable for most recreational divers, not sure about technical diving, that was before my time. Not bought this brand before but it uses the same Seiko auto mechanism of another brand I like that starts with "I" My very 1st diver's watch was an Omega Seamaster 300 and these watches for an awful lot less money are IMO just as good. I've delayed this review to see how well it keeps time, as good as you can expect for an automatic watch. The luminosity on the dial is pretty good too, lasts much longer than I would have expected. The Omega had excellent luminosity but for a watch of that time period (1969) it was probably radio active!! The bracelet is quite generous, I had to remove a few links. Excellent watch, very pleased with it.
