Review: Remarkable watch - 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 desertcart. 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 :) Review: Good to go - 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. ## Features - 🌊 1000M Water Resistance: Pressure-tested for depths of 1000 meters, perfect for professional divers and water enthusiasts. - ⏱️ Japanese Caliber NH36 Automatic Movement: Known for accuracy and reliability, crafted with precision by expert watchmakers. - πŸ’Ž Sapphire Crystal: Slightly domed for enhanced visibility and scratch resistance, magnifying the dial for clear reading - 🌟 316L Stainless Steel: Corrosion and rust-proof, offering long-lasting durability and a polished finish. - πŸ› οΈ Helium-Safe Valve: Fully functional Helium-release valve, ideal for deep-sea saturation diving. - πŸ‹οΈ Shock-Resistant: Built to withstand high-impact and concussive shocks, ideal for adventurers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D7C8CRS4 | | Additional Features | Glow In The Dark, Scratch-Resistant, Shock Resistant | | Age Range Description | Adult | | Band Color | Black | | Band Material Type | Silicone | | Band Width | 24 Millimeters | | Best Sellers Rank | #463,071 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #2,108 in Men's Wrist Watches | | Brand Name | RATIO | | Case Diameter | 47 Millimeters | | Case Material Type | Stainless Steel | | Case Thickness | 15 Millimeters | | Clasp Type | Buckle | | Clasp type | Buckle | | Closure Type | Buckle | | Crystal | Sapphire Crystal | | Customer Reviews | 4.2 out of 5 stars 332 Reviews | | Dial Color | Black | | Display | Analog | | Face Style | Diver | | Global Trade Identification Number | 00791126044961 | | Included Components | Diving Extension | | Item Type Name | Diving Watch | | Item Weight | 0.28 Kilograms | | Item type name | Diving Watch | | Item width | 24 millimeters | | Manufacturer | Ratio | | Manufacturer Part Number | 1068HA90-34VA-WHT | | Model Name | Ratio | | Model Number | 1068HA90-34VA-BLK-V02 | | Pattern | Solid | | Power Source | Mainspring | | Shape | Round | | Sport Type | Diving, Swimming | | Strap Type | rubber strap | | Style Name | Diver | | Theme | Dive/Military | | UPC | 791126044961 | | Unit Count | 1.00 Count | | Warranty Type | Limited | | Watch Movement Type | Japanese Automatic | | Water Resistance Depth | 1000 Meters | | Water Resistance Level | Water Resistant | ## Images ![RATIO FreeDiver Helium-Safe Dive Watch Sapphire Crystal Automatic Diver Watch 1000M Water Resistant Diving Watch for Men - Image 1](https://m.media-amazon.com/images/I/613GJPM1kWL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Remarkable watch *by K***R on March 8, 2024* I found it impossible to not fall in love with this watch.

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. ### ⭐⭐⭐⭐ Really a 4.5 rating *by N***R on January 27, 2026* 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. ## Frequently Bought Together - RATIO FreeDiver Helium-Safe Dive Watch Sapphire Crystal Automatic Diver Watch 1000M Water Resistant Diving Watch for Men - VVAY Petrol Lighter, Vintage Trench Leather Lighter for Man (Sold without Petrol) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/428182036-ratio-freediver-helium-safe-dive-watch-sapphire-crystal-automatic-diver](https://www.desertcart.hr/products/428182036-ratio-freediver-helium-safe-dive-watch-sapphire-crystal-automatic-diver) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-06*
