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.

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.

My breakdown and review!
I wrote a long and detailed review on my instagram about this watch/brand. I would love to partner with them. I fully support Ratio watches! As a collector! I took a chance and I have to say I am beyond blown away by the quality of this RATIO Free Diver. Even the packaging, and I love the logo/name. Apparently this mint color is selling a popular one, but I love all the colors they offer! -200m WR (Pressure tested) -Signed Screw down crown -Slight domed Sapphire Crystal -Plenty of AR coating -The lume is great! -The bracelet is solid with solid end links AND a nice milled clasp. -It literally has ZERO rattle when you shake your wrist. NH35 Seiko Movement -24 jewels 21,600 bpm -316l stainless steel -Zero sharp edges -40mm (I prefer 42mm) but this works -20mm lug width -Screw down case back -4 micro adjustments on the milled clasp that is also signed with the logo. -Great taper on the solid link bracelet -The Crown screws down better than most, and the size is great! -The crown guards are excellent -bezel action is flawless and lines up perfect. 120 clicks. -Perfectly applied indices (I especially love the diamond shape at the 12 o'clock) Don't you love taking a chance on a small company and they blow you away? I'm not kidding when I say RATIO may be a small company in Singapore, but they are doing incredible things. This watch feels just as good if not better than a lot of my more expensive watches. I had full faith in this company!

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

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.

Impressive!
Very nice piece of kit. I opted for the mint green dial face, called the 'Reef' on the Ratio website. Looks much better in hand than in the photos. The watch has a quality feel to it and can be hacked for accuracy. Has the Seiko NH35 Movement and thus far has been very accurate and within specs. You get a lot of watch at this price point. I thought it might be a little small for my 7 inch wrist, but once I got it and sized it to my wrist it's nearly perfect. Sizing is easy, pin & collar design and the bracelet is above average at this price. It's not janky and wears comfortably. I may try some different strap options later on, but for now, I'm pleased with the solid end link bracelet. Lume is also decent for the price. The watch has some weight to it, but it's well balanced and stays put on my wrist. Overall, I don't think you can do much better for an automatic that looks and wears this good for it's modest price. Highly recommended!

It’s cute and it works!
I love this thing! Feels solid. Looks solid. And works like a boss. Dove with it yesterday and it worked out pretty well. Had a couple dive buddies with their high end dive watches ask about it. They liked the look of it and one of them added it to their cart to buy. It’s water resistant for sure. Didn’t have a drop of moisture in it. It’s readable under water. The movement is smooth and accurate. The size of the case looks great on my wrist. Definitely worth it. I love the back with the diver on it. Glad I bought it.

El reloj está bien en general funcionando correctamente solo el bisel se juega un poco nada severo pero la caja donde viene el reloj es pésima al menos la que me llegó no se podía cerrar quizás solo haiga tenido mala suerte en general es un buen reloj
